Business functions rely a great deal on computerization. Basic office operations are usually facilitated by off the shelf software, however core processes are not serviced via these. The highly specific nature of how business works demand special software to fulfill its needs. Custom software development is an extremely important part of the computer sector.
The dominant products in this sector can be considered to be database applications. There is a specific need for applications of this type of safety because of the unique requirements that each business needs in order to manage their informations efficiently and effectively. Commercial programs cannot answer such demands of the enterprise. Various languages are used to develop these programs such as Java and C#.
Applications are used in this environment by being deployed by the client server model. Although the majority of these are desktop solution, many of them are being migrated to the web. Java and PHP have allowed web based deployment to become a lot easier due to their powerful scripting. CMS (Content Management Systems) have become popular and made it easy to setup database driven web applications.
They have increased in popularity due to the advantages they have over running applications on your desktop. This is because there is only one version of the app to be maintained, which is the one on the server. Because the application will be running inside web browsers there is no need to install program files on client computers. One of the biggest advantages is, once they have been uploaded to the web they are essentially accessible to anyone at anytime. This means that people can work anywhere, be it in their homes or out in the field. Due to this development important business transactions are no longer confined to the office.
Several customised applications are still running on desktops because there is no reason for them to be ported as web based programs. An example is software that is used for engineering control systems for machinery, electrical systems, and industrial processes. The programs combined with the hardware they control are contained within the enterprise, and therefore do not need to be accessed from the outside.
Wrappers to legacy database applications are one type of application. Perfectly functioning mainframe computers are still a regular occurance. To have additional features and a modern interface to the system customised software is usually used.
The need for custom software development is caused by the highly specific nature of business processes. Commercial off the shelf are unable to fulfil this need. This is how hundreds of programmers have been able to make a living creating and maintaining these solutions.
