摘要
当前软件开发中数据库建表和数据录入界面不能有效适应变化的需求。所建的表和所设计的界面只能适应特定的需求,很少考虑到同一领域内需求的相似性及系统对需求变化的适应性等,从而造成了大量的重复劳动和资源耗费,而且可靠性差、难以维护。文中在数据库设计理论和软件复用理论的指导下,针对以上问题提出了表结构的复用和界面设计的思想。表结构的复用和自动界面设计让本构件在广度和深度上都有了长足拓展,具有对变化需求的包容性和自适应性。而数据维护和界面设计构件正是其功能实现的内部支持,它不仅为开发人员提供了良好的编程接口,而且高级用户可在此构件上动态地改变表结构和数据录入界面,从而在用户需求变更时,系统有快速响应的能力,且使数据库在作微小改动的情况下能应用于不同的信息系统中。
Among the current software developments,create tables and data input forms can＇t validate to adapt to the need of the variety. The created tables and designed forms only can adapt to the particular need, and few in consideration of the adaptability of the alike in the same realm,system the variety＇s adaptability of right need and etc. So it makes a large quantity＇ s repetition labor and wastes resources, and depend badly,difficult to support under the guide of datebase design theories. This thesis puts forward the concepts of reusability of table structure and design of frame. The reusability of table structure and design frame automatically make ~his component more flexible in the extent and depth, possessing the capability of comprehensive and adaptive sustained by the data maintenance and frame design component which provides friendly program interface for developer and super users can change the tables＇ structure and data input frame on it, that makes the component respond rapidly to the changes of requirement and be adaptive to different systems with a little of modification.
