There are many systems currently in operation, however, which were developed before the need for change was understood. Such systems are commonly referred to as "legacy systems", and were developed with relatively short lifetimes in mind. Software engineering is a relatively young discipline which is continually improving to provide better support for the development of software systems. What were once state-of-the-art techniques, tools, and processes are now dated, and have resulted in systems which are not responsive to change. For historical reasons, dated development practice traded maintainability for other system attributes, such as cost and performance. A significant number of legacy systems remain in operation because they are critical to the business processes which they support. The combination of extended lifetimes and poor maintainability means that legacy systems are expensive to change, and in many cases they cannot accommodate emerging requirements. This is clearly an undesirable situation, which, until recently, has been tackled by replacing the system or attempting to maintain it | 出版日期 | Textbook 1999 | 关键词 | Factor; architecture; architectures; control; deployment; development; evolution; form; migration; modeling; m | 版次 | 1 | doi | https://doi.org/10.1007/978-1-4471-0817-7 | isbn_softcover | 978-1-85233-060-6 | isbn_ebook | 978-1-4471-0817-7Series ISSN 1439-9245 | issn_series | 1439-9245 | copyright | Springer-Verlag London Limited 1999 |
