When it comes to software engineering and dealing with software, there are various types of software maintenance in software engineering. Think of maintenance of software as you would of maintenance of machinery. In order to maintain machinery you need to oil it and such like so that you can keep it running, right? Similarly where software is concerned, you need to be able to maintain it to keep it running and for that there are so many types of software maintenance in software engineering- this is done so that the user of software can maintain the software without facing any glitches, bugs or such like.
Now maintenance of software does not always refer to fixing something that isn’t working- in some cases maintenance of software that works perfectly fine may be required and that is different and not at all similar to other types of software maintenance in software engineering. The first of these is adaptive software maintenance in which the software is modified to be able to deal with any changes that may be revealed or apparent in the environment of the software. This is done to keep the software running despite changes in the system itself. The software is modified so that it can adapt to the changed environment.
Another of the many types of software maintenance in software engineering is corrective maintenance. Any glitches and bugs discovered in the software are corrected so that users can use the software and so that it would operate and run smoothly as well. What happens is that in some cases users of the software may complain about certain glitches in certain software and so, the makers/manufacturers of the software will deal with it so that it can be fixed. You know how the iPhone 4 was released first and the iPhone 4S came right after? That was because certain bugs in the software of the iPhone 4 needed to be corrected and so, everything that was wrong in the 4 was then fixed in the iPhone 4S and that is how corrective types of software maintenance in software engineering takes place.
Then there are those types of software maintenance in software engineering where, though it may seem like the software is being ‘corrected’, the reason for maintenance is actually to improve the performance and, of course, the maintainability of the phone’s software. This is nothing like corrective maintenance- it has more to do with the overall performance of the phone itself.
These are just some of the many types of software maintenance in software engineering and there are so many others too. The thing is that software is used in so many devices and they all need to updated constantly and maintained just so that they can keep running. Software maintenance is like taking care of the wear and tear process of the software- it is done for numerous purposes but the main function is to keep the device and software running so that it can function for a longer time.
