MAINTENANCE

Once the software is delivered and developed, it enters the maintenance phase. After implementation systems need maintenance. Beyond monkey testing during Software development some errors may not appear. During its usage by the end-user with actual data certain errors may disclose.

Therefore some residual errors or bugs remain in the system that must be removed as they are discovered. Many of these surfaces only after the system have been in operation sometimes for a long time. These errors once discovered need to be removed on an urgent basis for the smooth running of the system, leading to the software getting changed. Though Maintenance is not a part of software development, it is an extremely important activity in the life of a software product.

Maintenance involves understanding the existing software (code and related documents), understanding the effects of change, making the changes-to both the code and documents-testing the new parts and retesting the old part. For successful and smooth running of the system, maintenance is the prominent part of the project.

Any error, which hinders the functioning of any part of the project, may lead to bad impression of the developer.

There are majorly two types of errors: Compilation error and Runtime errors.

Compilation errors are errors during coding and are to be taken care by the developer during development process.

Runtime errors are those which occurs during running of the program. Whenever there is an occurrence of error an ‘Error Window’ opens in the middle of the screen displaying the type of error, Error Number and the Nearest Possible reason as to why the error has occurred. With the occurrence of this Error Window the operator (End-user) should note the type of error, the error number and the description of the error and should immediately report to the concerned Developer or Administrator.

Now comes the role of the Maintenance Personals. After knowing the entire details from the end-user like where or at which screen does this error occurred or what type of data was feeded by the user or the point of malfunctioning. Considering this error as the main reason for the malfunctioning the programmer now re-examines all the possible factors, which act behind the particular screen where error has occurred.

After debugging the required error the programmer itself tests the same screen or process with dummy data. Only after getting completely satisfied with problem rectification the programmer compiles and runs the program.
