Why Do We Need Software Engineering?

To understand the necessity for software engineering, we must pause briefly to look back at the recent history of computing. This history will help us to understand the problems that started to become obvious in the late sixties and early seventies, and the solutions that have led to the creation of the field of software engineering. These problems were referred to by some as “The software Crisis,” so named for the symptoms of the problem. The situation might also been called “The Complexity Barrier,” so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is far from over, but thanks to the development of many new techniques that are now included under the title of software engineering, we have made and are continuing to make progress.

In the early days of computing the primary concern was with building or acquiring the hardware. Software was almost expected to take care of itself. The consensus held that “hardware” is “hard” to change, while “software” is “soft,” or easy to change. According, most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software didn’t work, they believed, it would be easy enough to change it until it did work. In that case, why make the effort to plan?

The cost of software amounted to such a small fraction of the cost of the hardware that no one considered it very important to manage its development. Everyone, however, saw the importance of producing programs that were efficient and ran fast because this saved time on the expensive hardware. People time was assumed to save machine time. Making the people process efficient received little priority.

This approach proved satisfactory in the early days of computing, when the software was simple. However, as computing matured, programs became more complex and projects grew larger whereas programs had since been routinely specified, written, operated, and maintained all by the same person, programs began to be developed by teams of programmers to meet someone else’s expectations.

Individual effort gave way to team effort. Communication and coordination which once went on within the head of one person had to occur between the heads of many persons, making the whole process very much more complicated. As a result, communication, management, planning and documentation became critical.

Consider this analogy: a carpenter might work alone to build a simple house for himself or herself without more than a general concept of a plan. He or she could work things out or make adjustments as the work progressed. That’s how early programs were written. But if the home is more elaborate, or if it is built for someone else, the carpenter has to plan more carefully how the house is to be built. Plans need to be reviewed with the future owner before construction starts. And if the house is to be built by many carpenters, the whole project certainly has to be planned before work starts so that as one carpenter builds one part of the house, another is not building the other side of a different house. Scheduling becomes a key element so that cement contractors pour the basement walls before the carpenters start the framing. As the house becomes more complex and more people’s work has to be coordinated, blueprints and management plans are required.

As programs became more complex, the early methods used to make blueprints (flowcharts) were no longer satisfactory to represent this greater complexity. And thus it became difficult for one person who needed a program written to convey to another person, the programmer, just what was wanted, or for programmers to convey to each other what they were doing. In fact, without better methods of representation it became difficult for even one programmer to keep track of what he or she is doing.

The times required to write programs and their costs began to exceed to all estimates. It was not unusual for systems to cost more than twice what had been estimated and to take weeks, months or years longer than expected to complete. The systems turned over to the client frequently did not work correctly because the money or time had run out before the programs could be made to work as originally intended. Or the program was so complex that every attempt to fix a problem produced more problems than it fixed. As clients finally saw what they were getting, they often changed their minds about what they wanted. At least one very large military software systems project costing several hundred million dollars was abandoned because it could never be made to work properly.

The quality of programs also became a big concern. As computers and their programs were used for more vital tasks, like monitoring life support equipment, program quality took on new meaning. Since we had increased our dependency on computers and in many cases could no longer get along without them, we discovered how important it is that they work correctly.

Making a change within a complex program turned out to be very expensive. Often even to get the program to do something slightly different was so hard that it was easier to throw out the old program and start over. This, of course, was costly. Part of the evolution in the software engineering approach was learning to develop systems that are built well enough the first time so that simple changes can be made easily.

At the same time, hardware was growing ever less expensive. Tubes were replaced by transistors and transistors were replaced by integrated circuits until micro computers costing less than three thousand dollars have become several million dollars. As an indication of how fast change was occurring, the cost of a given amount of computing decreases by one half every two years. Given this realignment, the times and costs to develop the software were no longer so small, compared to the hardware, that they could be ignored.

As the cost of hardware plummeted, software continued to be written by humans, whose wages were rising. The savings from productivity improvements in software development from the use of assemblers, compilers, and data base management systems did not proceed as rapidly as the savings in hardware costs. Indeed, today software costs not only can no longer be ignored, they have become larger than the hardware costs. Some current developments, such as nonprocedural (fourth generation) languages and the use of artificial intelligence (fifth generation), show promise of increasing software development productivity, but we are only beginning to see their potential.

Another problem was that in the past programs were often before it was fully understood what the program needed to do. Once the program had been written, the client began to express dissatisfaction. And if the client is dissatisfied, ultimately the producer, too, was unhappy. As time went by software developers learned to lay out with paper and pencil exactly what they intended to do before starting. Then they could review the plans with the client to see if they met the client’s expectations. It is simpler and less expensive to make changes to this paper-and-pencil version than to make them after the system has been built. Using good planning makes it less likely that changes will have to be made once the program is finished.

Unfortunately, until several years ago no good method of representation existed to describe satisfactorily systems as complex as those that are being developed today. The only good representation of what the product will look like was the finished product itself. Developers could not show clients what they were planning. And clients could not see whether what the software was what they wanted until it was finally built. Then it was too expensive to change.

Again, consider the analogy of building construction. An architect can draw a floor plan. The client can usually gain some understanding of what the architect has planned and give feed back as to whether it is appropriate. Floor plans are reasonably easy for the layperson to understand because most people are familiar with the drawings representing geometrical objects. The architect and the client share common concepts about space and geometry. But the software engineer must represent for the client a system involving logic and information processing. Since they do not already have a language of common concepts, the software engineer must teach a new language to the client before they can communicate.

Moreover, it is important that this language be simple so it can be learned quickly.

What is the Purpose of ERP Software?

Enterprise Resource Planning (ERP) software can be described as a complete business software solution. It is aimed at the integration of all business processes and sub-processes into a single unified system. This system is formulated and implemented in an organization to effectively and efficiently achieve the business goals of the organization.

ERP packages are implemented to manage the existing and prospective business plans and policies in an efficient manner under strict deadlines. It can be referred to as the ultimate business solution package that is predominantly concerned with making sure that the available resources of the organization are utilized in the best possible manner and coordinated with the business objectives of the organization.

It is crucial that modern day business organizations have a single unified system, which aims at harmonizing its business efforts. This can prove to be a crucial determinant in deciding the scope, area and net results of the organization as a whole, rather than running many different systems that don’t work well together. What makes ERP different from any other business solution package is the presence of a single and unified database system.

ERP software is as essential to the needs of a business today as food is for living. Businesses cannot run competitively in the absence of properly drafted and formulated ERP software. The more effective implementation and follow-up, the better are the results. ERP software is needed by all modern-day organizations, irrespective of the size, area of operations and business objectives.

Nowadays there are many ERP packages available in the global market, including SAP, PeopleSoft, Oracle, J D Edwards, and BAAN.

The selection of an ERP software package is dependent on many factors: previous software implementation, nature and size of operations, recommendations of consultants, and management decisions.

Before installing specialized software, a detailed study must be made and reviewed to match the business requirements with the available packages. This must be taken as a serious study as any mistake in selection or its effective implementation can prove disastrous to the organizational objectives and prospects. The ERP software must be installed by an ERP vendor or third-party consulting organization, which are expert service providers when it comes to providing Consulting, customization and support.

Some of the benefits of ERP Software:

* All processes and sub-processes are linked and unified into a single system.

* There are enhancements in the field of productivity, efficiency and achievement of business objectives.

* ERP tends to considerably reduce the response time by effectively transferring crucial information.

* ERP helps in streamlining the numerous functions performed by the organization as a whole.

* It helps the management to make vital decisions with unparalleled accuracy and in-depth study.

Thus, ERP software can effectively change the outlook of any business organization that exists in today’s cutthroat business world. Proper implementation of the ERP software is the key factor, which can benefit the growth prospects of any organization.

Strengths and Weaknesses of Waterfall Approach for Software Development

One of the most famous and widely used approaches for software development is the waterfall model. Waterfall approach is an old technique that has been in use for quite some time, but in modern times agile approach is gaining prominence.

Waterfall approach, as is evident from the name, refers to a systematic approach where one step comes after the other. It cannot go the other way round. The process works like the waterfall effect that flows in one direction, which is from up to down.

In this process the life cycle of the development process is predetermined. All the steps are defined before the start of the project. The approach is predictive, where the team is well aware of the order of each step and therefore works accordingly. It starts from the requirement analysis, the design phase and then proceeds on to the implementation, testing and the maintenance phases.

The waterfall approach can be quite beneficial for those who are quite clear on their requirements. A planned approach works for them because they want fixed processes and budget. Where fixed processes are beneficial, at the same time they can be inconvenient at times. In cases where the client is not clear on the requirements and finds in the middle of the project that he/she wants to change course, this approach can prove to be quite problematic.

Another point of the waterfall approach is that the requirement analysis and design of architectural structure can consume a lot of time. Extensive research is done initially as the next phases depend completely on the planning strategy. However, the good thing is that everything is thoroughly worked out and each aspect is studied beforehand. The developers in such cases know what is expected of them.

A waterfall approach works in a systematic order, with one step following the other and the testing phase comes in the end. If there are any big problems encountered in the testing phase, it means a long process to make the amends. The process can consume extra time and money.

We cannot conclude that one approach is better than the other, as every method would have its own strengths and weaknesses. The determination of success for each method depends on how it is being used and whether the approach suits the scope of work being undertaken. While one approach may be suitable for a particular project, it might become totally useless under different circumstances. For example, some believe that agile methods are not well suited for offshore development, as they require a closer contact and communication that is not possible in an offshore project.

Advantages and Disadvantages of Professional Shopping Cart Software

Advantages & Disadvantages of professional shopping cart software As e-Commerce is becoming a regular technique in the business industry it appears that more and more software development firms are developing professional shopping cart software to be released in the market. There is currently a huge range of free shopping cart software that has been released, and it seems that most e-Commerce website owners prefer these free systems over paid for professional shopping cart software. In this article we are going to look at the advantages and disadvantages of professional shopping cart software.

Advantages

• Even though you will have to pay for the solution, you get a cart package that has been fully developed, tested and used in the real working world by other e-Commerce websites. If the solution is used by a popular website service then the chances are it has been under more than enough testing to be deemed ready for use.

• Professional shopping cart software will be supported by the people who developed it. A lot of free solutions out there are simply developed and then discontinued as the freelance developers move onto their next project. Support is essential if you are going to want upgrades as mentioned in our next point.

• As the system is supported, the development team are likely to fix any bugs that may occur and provide patches and security fixes. This means the shopping cart software will only get better as time goes on and furthermore improve your e-Commerce website.

• Your site is likely to be more secure when using a professional software solution as in most cases the it developed house private content management systems. This improves security as public content management systems such as WordPress are constantly under threat from hackers as they try to compromise the free source code.

• Another huge advantage of using professionally developed software in e-Commerce is that they will already support a huge range of different payment options for your customers. There are various carts – that only offer PayPal for payment by standard, and it can take a very long time to find plug-ins or figure out how to add other methods yourself. With professional software you can save time and possibly money as it is all included.

Disadvantages

• Your e-Commerce venture might be a small time project and professional cart does cost money which you may not have. In this case you may have to make do with a free shopping cart solution. The good part of conducting business online is that after you have made profit with the free system you can reinvest your money to buy a professional package.

• You trust the developers to do everything they promise to ensure the best experience. It might be slightly difficult to use at first and you might have to spend some time getting used to the bespoke system. You also have to understand that you are vulnerable until patches are made if a security flaw is found.

How to Retrieve Deleted Text Messages & Not Go Crazy in the Process

It’s happened to all of us. We’ve deleted a text message only to realize a short while later that we either deleted the wrong message, or we need to retrieve information off one of the deleted text messages. We then frantically search out ways online how to retrieve deleted text messages hoping to find an easy solution. We pour through websites pulling our hair out because we can’t find an easy solution.

Ultimately we walk away dismayed because either we were not able to find any solutions on how to retrieve deleted text messages, or the solutions we found seemed to require so much “detective” work, that the solution itself should be on a an episode of CSI.

Are there really any “easy” ways to retrieve deleted messages?

The good news is that YES, there are a couple options that do exist which enable anyone to easily recover deleted texts, and both are not only very affordable, but both work exactly as advertised.

Before we dig into the solutions, there is one solution that is often discussed, which does not work, although many people do still talk about it.

What does NOT work?

Going to your own phone carrier is not going to be a viable option. Yes, they are required by law to keep records of your communication (SMS, call, etc.), but they are not required to turn over their logs to you, unless requested by a court of law. You cannot call up AT&T, Verizon or Sprint and tell them you want to retrieve a deleted text message from last week because there is something really important within the contents of the message. It just wont work.

The only information AT&T, Verizon, Sprint, or any other cell phone carrier is going to provide you is the number, date, and time of a call or message. You can plead all you want, but they will not be able to do anything, so it’s not worth your time to attempt this approach.

What DOES work?

There are actually two options available for anyone who is looking for information on how to retrieve deleted text messages. These options rank from the “quick and easy” to the more difficult, but also the most effective.

1) Quick & easy method.

The ‘quick & easy method’ is to buy a SIM card reader, often referred to as a SIM card spy device. This device looks like a USB reader, and the way it works is you remove the SIM card out of your phone, and then place the SIM card into the SIM card reader, and then plug the reader into your computer. Using the included software (of the SIM card reader), you’ll be able to immediately retrieve and read deleted text messages. The time frame will vary, based on what new information is overwritten on the SIM card, but you’ll at least be able to retrieve and read the last 15-20 messages and scan through your call history and contacts, even if they were all deleted.

Positives of this approach?

  • Very easy.
  • Enables you to quickly recover deleted messages.
  • Does not require software to be installed prior to the message being deleted.

Negatives of this approach?

  • A bit costly.
  • Limited cell phone support.
  • Does not work on CDMA networks.

2) More difficult, but most effective method.

The more difficult, but most effective method’ is to purchase a cell phone monitoring app that is often used to spy on cheating spouses, monitor teen cell phone use, track cell phone location, and locate missing or stolen cell phones. These apps (often called spy apps or spy phone software) are often used by people who want an easy and convenient way to back up and store all their own personal cell phone data. The reason why this method is fast becoming a popular way to back up their own personal cell phone data is because everything happens automatically. There is no “syncing” required, or any buttons or settings to worry about. Your cell phone data (text messages, call history, etc.) are automatically backed up every single day. This means if you ever delete a text message, and then need to quickly recover it, all you have to do is log onto your account and then in just a few clicks, you’ll have full contents of every message that was either sent or received from your phone. In addition, you’ll get access to all your call logs and contacts.

The reason why this is a more difficult method, is because it requires that you download the software from your cell phone’s web browser and install the application on your phone. Not everyone is comfortable downloading cell phone apps from the internet using their phone’s web browser. However, once you do complete the download, the actual installation is similar to installing an app on your computer. If you are willing to roll the dice and go with this method, you’ll be very happy with the results. It’s essentially a real time person back up solution that requires absolutely ZERO work on your part. Everything is done for you. The only drawback with this approach is that it does require you to install the software BEFORE you delete the text message that you want to retrieve. This means you need to be proactive and install the software ahead of time.

Positives of this approach?

  • Extremely effective.
  • Affordable.
  • Full contents of text messages are retrieved.
  • Large amount of cell phones are supported, including the popular models such as Android, BlackBerry, iPhone, Nokia, and more.

Negatives of this approach?

  • Can be difficult if not familiar with installing cell phone apps.
  • Software must be installed prior to message being deleted.
  • Requires a data connection such as 3G or Edge
  • May increase data fees if a large amount of text messages are sent on a daily basis.

There you go. Now you know how to retrieve deleted text messages using a couple different approaches. The next time someone asks you how to retrieve deleted text messages, you’ll know what options exist, and which one is the best for that particular situation.

Good luck!

How Has Technology Changed Art?

We all are witnessing the changes being made in the art these days. Technology has the power to change anything. It is changing the traditional art into digital art.

Amazing digital art has taken place of traditional art. Digital art is exploring itself in many different ways that one can imagine. Different software is developed to increase the presence of digital art.

Photoshop Artists are one of the most common digital artists who give an amazing look to a picture with the help of imaging software and different applications.

These applications are developed with the help of technology. Anyone can be a digital artist having knowledge and proficiency in Photoshop.

Difference between traditional artists and digital artists is that traditional artists use paint and cement for their art and digital artists use imaging software and applications in their art. Some of the applications have the power to create 3D art work.

Technology has taken art into a new level of creativity. Let us talk about how technology has changed traditional art into digital art. We know that internet is ruling the world with its power. So, artists decided to present their art online with the help of internet. This is possible with use of technology.

You must have seen art galleries and attended painting exhibitions in your life. These doesn’t work well these days so artists find a way where they can get more attention and more praise for their work. Most of the artistic stuff is now seen online and is circulated to the art lovers.

There are some places where exhibitions are held and we do respect them. But presenting paintings, sculptures and art work online is in trend. Some of the artists are also showing their art on the basis of card swipe panel or coins.

How this work – when you enter coins or swipe card in the panel, the panel shows you some of the art work for a few minutes and then gets closed and if you want to see it again or explore more, further you need to swipe your card or add coins into it. This is how artists are using technology.

How digital artists are using technology for their art work

Digital artists already in touch with technology are aware of the systems that are in trend and use them to create their art work and sell them online.

Some of the professional digital artists are earning a lot of bucks by selling their art work. They can also design the ones that you want and are also ready to make any modifications you need.

They use different software to explore their skills and made it more impressive. They are using technologies that offer new ways to express their art work in a realistic way for much more time.

They are using different types of media and mix them to provide a more creative art work. Their 3D art work looks as real as it is present live in front of you.

Technology not only brings changes in education, medical field, industry and business but also brings a huge change in the art work and the artists as well.

Technology opens different paths for the artists to enter into for a good earning. They made their profession more powerful along with their art work.

In our busy lives we hardly get time to meet each other and our loved ones. How can it be possible to see exhibitions and galleries? So technology has brought this change in the art workers to show their skills and talent to people from anywhere in the world.

Technology is getting advanced and making more useful for the common man as well as artists. Technology has provided us with several things that we should be thankful. One of them is digital art work.

Visualwize Chess Training Software: A Review

Chess enthusiasts of all levels are always seeking ways to improve their chess skills, so that they can win at chess games, whether they play professionally or socially.

One of the most effective ways to improve your chess skills is to use a chess visualization software, which enables you to practice and improve your visualization skills. Visualization is one of the most important skills you need to succeed in chess.

A program that is apparently gaining a lot of popularity and is helping many people to improve their chess is Visualwize Chess Training Software.

Let’s address the basic questions on this software.

What is it?

Visualwize is a chess training software that trains your ability to have a clear mental picture of chess moves before you make these moves on the board. This enables you to assess the implications of your moves before you make the actual moves. This therefore enables you to play better at chess, as you will be able to make the right decisions and avoid making some mistakes that would make you lost a game.

This program has 240 visualization training exercises which are designed to develop your visualization skills. It has and more than 1200 moves to visualize. These moves are real moves made by a master player in real chess games. With the software, you can train to visualize up to 8 moves ahead.

The program consists of 4 levels, level 1 being rather easy and level 4 being hard. You can order the level that suits your needs. For those who really want to significantly improve their skills, level 4, the complete program, is recommended.

How does it work – what does the program actually do?

In simple terms, the program shows a chess position from a game between two chess masters, and then, with arrows, it shows the next few moves that have been made in that position by the renowned chess masters. The arrows stop in a position where a tactic, i.e., a combination that wins the game exists.

Unlike other programs and books that use written annotations for the moves, this program uses arrows on the board. This means it reflects a realistic playing scenario, and you don’t have to take your attention and eyes from the board to read written annotations.

This is one major factor that separates this program from others that are available on the Internet today. Rather than building up the skill of moving your eyes between notation and the board, Visualwize trains you in the art of seeing unfolding moves without actually affecting the board.

On the website where the program is offered, there are many informative and short videos that you can watch, which describe how the program works.

Why is it important – what benefits can you get from this program?

It is recommended that chess players wanting to take their chess to the next level use this program because it offers several benefits:

  • You will be able to see more chess moves ahead, before you actually make any move on the board, giving you an opportunity to assess the consequences of every move before you make it.
  • You will avoid making mistakes which can make you lose a game in an instant.
  • You will make the most of your training time since you will be able to easily visualize the notation below chess diagrams.
  • You become an efficient and effective chess player – you won’t need to calculate variations several times over because you will be able to clearly the consequences of your move in your mind, saving you a lot of time.
  • You will make a wise investment that will help you significantly improve your chess – the program is favourably priced at only $30. If you were to hire a chess coach, you would pay a very high fee per hour of the coach’s time to train you.
  • It is convenient – once you purchase the program, you can train at any time of the day or night, as much as you want.

With several books and programs on how to improve chess, available today, Visualwize is considered to be a cut above the rest among many chess enthusiasts.

How to Change the MPI Node Address For a Siemens S7-300 PLC

I have seven Siemens S7-300 PLCs connected together using the MPI (Multi Point Interface) interface. The Siemens MPI protocol is used by Siemens PLCs to communicate with external devices. I want to rename each of the seven PLCs. Here are the steps to accomplish that task.

First, connect your MPI cable to the first PLC. I will be connecting my laptop to each PLC individually. Power up the PLC and open Simatic Manager. The "New Project" Wizard window will open. Just click Cancel to close the window. Now click the Accessible Nodes icon on the toolbar. A window will open showing the identification of the PLC you are connected to. My window is showing MPI = 2 (directly). Make a note of this address and close the window.

Next we need to download a hardware configuration to the PLC. This is where we will rename the PLC node address. There are probably a couple of different ways to do this – following is how I accomplish this. All seven of my PLCs are the same model; Therefore, I am using the same hardware configuration. For the obvious reasons, I want to give each a different MPI node address. I have a project file that contains all seven of my PLC programs and one hardware configuration file. I open the one hardware configuration file, and then double click Hardware in the right hand window. This will open the HW Configuration window. In this window you should see your PLC with its MPI address given.

Remember when we clicked the Accessible Nodes icon and saw MPI = 2 (directly)? My Hardware Configuration Window is showing a MPI address of 7. Place your mouse cursor on the 7 and double click. Your CPU Properties window will open. It should open to the General tab. Look down and you will see Interface Type MPI with an address of 7. Click Properties and the MPI interface Properties window will open. Using the pull down menu, choose your MPI node address and make sure the MPI (1) 187.5kbps is highlighted and click OK.
