What is software maintenance?
Software maintenance is a process by which the computer program is changed or updated after release. While the term 'maintenance' can mean corrections and corrections of errors, only part of this process, referred to as "corrective", is intended for this purpose. Many software maintenance is used for "adaptive" work that ensures that the program continues to be efficient and usable for changing environment, as well as "perfect" procedures that improve the function. The “preventive” maintenance is used to facilitate the process in the future by providing additional documentation and tools that will be easier to update. These files are installed by a computer user and modify the functionality and design of the basic program in the system. This is done after the program has been released, although timely software development should be considered.
Software maintenance is a process of developing a program change that corrects errors or solves problems. This does not add any new features if they no longer exist but cannot be used because ofError in programming. Only about one quarter of all software maintenance is used for corrective problems, but it is often considered the most important element of program users.
A large part of the software maintenance is referred to as an "adaptive" that is used to edit the program to work in a new environment. Programs are usually designed and developed to function on certain operating systems (OS). While some software can work in newer versions, there are many programs that cannot do so. The adaptive patch of the program could change the code so that it can function properly on the new system and keep it up to date and usable.
Perfective software maintenance is used to add new features to the product and to make changes that can directly affect users. For example, the company could issue a text processing program that includes several spelling checks. If uA free repair that updates the dictionary in the program and creates additional options for correction of errors, would then be considered perfect maintenance. These upgrades are usually relatively small, because the main overhaul usually requires release of a new version or "client" software.
developers can also work on preventive software maintenance used to simplify future changes. After development, the company can realize that there is a potential for a mistake that has not yet developed. They can release the repair to solve this problem before it actually becomes a problem. Further documentation and cleaning of the code can also be made to make future maintenance easier or unnecessary.
