研究面向对象可视化建模及支持建模的 CASE环境 ,为了保证存入信息资源的一致性、完整性和方便灵活的共享性 ,研究 CASE环境的数据存储机制 ,讨论了中心库的组成和组织模式 ,提出了文件方式、数据库方式和综合方式 3种可行的中心库方案 .在对 3种方案论证、比较的基础上 ,进行了数据结构的设计和实现 ,并应用于所研制的 UML-

Studies visual object oriented modeling and the CASE environment that supports it. In order to guarantee the conformity, integrity and flexible sharing of the information in storage, the paper also studies the data storage mechanism of the CASE environment. Accordingly, it discusses the composing and managing pattern, and then brings forward three feasible repository schemes viz. the file method, database method and the integrated method. On the basis of discussion and comparison of the three schemes, it performs the specific design and implementation of the data structure. In addition, they are applied to the CASE UML platform developed.
