DEVELOPMENT OF SOFTWARE
Software developers may install purchased software or they may write new, custom-designed programs. The choice depends on the cost of each option, the time available to write software, and the available to write software, ands the availability of programmers. Typically, in large organizations computer programmers are part of the permanent professional staff. In smaller firms, without programmers, outside programming service may be retained on a contractual basis. Programmers are also responsible for documenting the program, providing an explanation of how and why certain procedures are coded in specific ways. Documentation is essential to test the program and carry on maintenance once the application has been installed.
The standards enforced were in conformance with development statement manual of KRISHNA MEDICAL CENTRE. Before starting any coding of any subsystem we were required to carefully study the information and requirements regarding that application. Once the problem was well though off, ands ideas were shared/ discussed among other team members about, how exactly the user interface should be and what is the best way to deduce the logic of the application, we are required to write down the flow of logic and other parameters being used or getting affected on a document of KRISHNA MEDICAL CENTRE called program specifications document (P S D). This P S D has to get approved from, our manager and users to get further suggestions; also this P S D’s are used to prepare the documentation of the final system at later stages and help to keep trace of the changes subsequently made in logic. The whole application is maintained in the menu from so that it remains user friendly and easy to use and less complex. The system security is maintained by means of the starting form, which takes the required user name and the password.
