面向对象工程数据库管理系统中“方法”的一种实现机制

Realized Mechanism of Method in ObjectOriented Engineering Database Management Systems

采用系统和“方法体”之间的参数传递及结果返回直接借助于操作系统的方式来解决“方法”的实现机制。以动态连接库的方式实现了“方法”的动态联编 ,对内存的需求量小 ,提供了相应的“方法”调用机制 ,容易实现 ,解决了 OODBMS中的一个棘手问题。

Realizing mechanism of method is solved by adopted the parameter delivery of the system and the method body and the result return with the direct help of the operation system.Method dynamic binding is realized by using dynamic link library. Less memory is required in this mechanism. Method call mechanism that is easy to be realized is provided in this paper. A difficult problem is solved in OODBMS field.
