【摘要】 数据在信息系统中的使用面临着这样一个困难,即数据存储是以关系模型为基础,而软件开发以对象模型来进行,造成了软件开发中数据访问技术的不和谐。在软件实现上陷入两种模式的转换工作,破坏面向对象语言的面向对象性,造成开发效率低下,代码重用率变低。提出并建立了一个软件框架,利用它提供的处于关系数据库和客户端之间的API来进行基于对象的数据库访问,充分发挥两种不同模式的优点,以提高软件开发的效率。更多还原

【Abstract】 The using of data in information system is confronted with such a difficulty that data storage is based on relational model while software development is under object model.It makes a disharmony between software development and data access.It causes software realization change from one model to the other,destroys object-oriented character of the object-oriented language,and brings about the poor efficiency and code reusing.Here brings up a software framework,in which API between relational database and client can access relational database based on object model.The framework elaborates the merits of two models fully and improves efficiency of software development.更多还原
