A legacy system is a system that essentially belongs to a previous generation, in a manner of speaking. It is typically an old system that despite its age and lack of modern compatibility still exists and continues to be in use. This is not because the users have found no reason to change it though. The fact of the matter is that it meets their requirements and does not present any problems while doing so. However, the more practical reason is the fact that it would be too expensive to have it replaced or overhauled. On top of that, a legacy system usually commands an important project, and so it would be too difficult to temporarily put it offline or to replace it. However, as with everything, there is always need for change. A legacy system may present problems and limitations to the organization, and stubbornly holding on to it may result in major repercussions, not only for the organization, but also the users who interact with it. One of the limitations of many a legacy system is the fact that it runs on old hardware, which may be obsolete. This can result in a lack of efficiency in that the legacy system in question may be too slow with relation to processing speed demands. Even finding spare components to replace those that may have gotten spoilt may be extremely difficult. Furthermore, though said spare components are found, constantly maintaining a legacy system can be counterproductive in the fact that the profits generated would have to be ploughed back into a depreciating asset. However, should...

Software migration, also known as computer migration, data migration or Personal Computer (PC) migration is moving the data and applications from one computer to another. The reasons can be because the user has either purchased a new computer, or the computers at the workplace have been upgraded to new systems. Due to the importance, or difficulty of replacing the original files and programs, the user prefer to have everything go with them to the new machine or system. Usually software migration can be done manually using software tools specific for this operation, over a data transfer cable, the link between the two computers. More often than not, full transfer of all the data and software from the source to the destination machine is not entirely necessary. Software migration in the above mentioned fashion can be entirely avoided by making use of external storage devices that will manage to store all the necessary data. Other organizations provide an internet solution for software migration, in that they allow for internet storage. This means instead of using an external hard disk for example, the user will use the internet to keep all the necessary information, and then download it onto the new machine. This removes the need for a full software migration. However, these methods do not work in the business environment. This is because some software has its necessary files in sections of the hard disk that cannot be accessed by users for one reason or another. This would result in the application reverting to the default settings, or completely malfunctioning, resulting in the...

Power builder is an integrated development environment used to create applications. PowerBuilder to .Net is a combination of PowerBuilder and Microsoft’s .Net platform; the latest in software migration that has revolutionized the world of applications development. Though originally designed to compete with Microsoft developed IDE’s, the Power Builder to .Net integration was created to allow continuity for the PowerBuilder project and to take advantage of the .Net platform that many developers are now using to create business critical applications. The PowerBuilder to.Net IDE is preferred by many application developers as it is a fast, cost-effective and easy application development software. The typical PowerBuilder to .Net business application is high performance and data driven. Technology used in PowerBuilder to.Net is also unique in that it continuously evolves to accommodate the latest software advances and business needs. This ability to keep up with advances in VUI (Visual User Interface) advances as well as functionality creates valuable competitive advantage for businesses that use the PowerBuilder to .Net platform. One of the reasons the PowerBuilder to .Net platform is favoured as rapid application development software by developers is its speed and simplicity. This development speed is attributed to the original PowerBuilder to .Net ‘DataWindow’ technology. This function imported from the PowerBuilder Classic version allows developers to use minimal coding to create data rich applications. Thanks to DataWindow, developers using PowerBuilder to .Net only need to use five lines of coding script to apply custom business logic. The simplicity created by the PowerBuilder to .Net technology through its declarative programming environment, coupled with increased levels of abstraction...

SOA or in full, Service Oriented Architecture is a technology that shares resources on a network within the workplace, to be accessed when needed by the users. Unlike the other system architectures, SOA is more flexible and in that the resources that are being shared are connected and can be made use of at the same time. It is the best choice for a network of especially great numbers, in that there many users on the network. Also if there are users who will connect remotely, it is a good approach to use spread the resources. By using SOA, each of the services provided will make use of the software system individually, while making use of the same system. As much as it sounds wasteful and over bearing on the system, it is not. Given that the services on the SOA are making use of the system that they are on, they are only producing different outcomes to that of each user; however it is the same service or action. An example of SOA is the use of ATMs (Automated Teller Machines). The concept is that the individual (remote) users can each have access to the banking services, in a kind of unique way to them. Now when we apply the SOA approach, the users will make the use of the “Retrieve balance” on the system, however, the results will be the balance of their own bank accounts. This is the same if a company makes an internet based request. In the end the same system is being made us...

Software development is when a user desires to create new software or, usually, upgrade their already existing system for a more efficient one. The users can be as diverse and large as an entire corporation or organization, a team that relies heavily on said software or even a small group of individuals. Once they establish that they wish to create a new system or upgrade said existing system, they will be required to devise and implement a master plan which will lead to the creation of this new system. Several steps are required to complete this software development process. This includes, but is not limited to, working out what the system needs to accomplish, developing it accordingly, writing out the code, thorough testing and debugging, and finally launching, should everything work out. This development process can take as few as a motivated programmer to several or even hundreds of developers. To establish what is required from the system, in other words, the problem(s) that it must solve, there has to be research. Sometimes the problem can be a common one, requiring the creators of new software to make theirs to solve the problem in a way that puts their product ahead of their competitors. However the problem can be entirely new, requiring the team to come up with a method of resolving it. Finally, it can be a recent problem that has been discovered, making the previous software obsolete, requiring a new creation to resolve said problem. And so, at this point of software development, the goals that are meant to be attained are...
