When first formulated in the early seventies, the laws of software evolution were, for a number of reasons, not widely accepted as relevant to software engineering practice. Over the years, however, they have gradually become recognised as providing useful inputs to understanding of the software process.

Software Evolution and Maintenance

Software maintenance is widely accepted part of SDLC now a days. It stands for all the modifications and updations done after the delivery of software product. There are number of reasons, why modifications are required, some of them are briefly mentioned below:. Market Conditions - Policies, which changes over the time, such as taxation and newly introduced constraints like, how to maintain bookkeeping, may trigger need for modification. Client Requirements - Over the time, customer may ask for new features or functions in the software.

Show all documents An evaluation of traceability approaches to support software evolution EB approach assumes that there are already available links between requirements and UML artifacts including test cases. Source code is excluded. The approach then runs its maintenance mechanism upon those artifacts and their links. The artifacts scope of EB approach includes all high- level and low-level artifacts UML design documents, i.

To change or not to change, that is the question? Or should we rather say change or perish!!!!! How many systems do the software engineers start building from scratch today? Well, not many. How many systems do the software engineers support today? The majority. Therefore, the success of many software organisations will strongly depend on how well they may support evolve and maintain these systems.

Partial Domain Comprehension in Software Evolution and Maintenance Abstract: Partial comprehension is a necessity in the evolution and maintenance of very large software systems. The programmers form not only partial comprehension of the code, but also partial comprehension of the application domain. To describe the comprehension process, we introduce ontology fragments and investigate how programmers form, use and extend them before and during concept location; concept location is a prerequisite of code changes.

Я люблю тебя, Сьюзан, - подумал.  - Помни это…. Ему казалось, что с него сорваны все внешние покровы. Не было ни страха, ни ощущения своей значимости - исчезло. Он остался нагим - лишь плоть и кости перед лицом Господа. Я человек, - подумал. И с ироничной усмешкой вспомнил: - Без воска.
