SDAI的C++联编及其基于VERSANT的实现

C++ BINDING TO SDAI AND ITS IMPLEMENTATION BASED ON VERSANT

ＳＤＡＩ是ＳＴＥＰ的标准数据访问接口，Ｃ＋＋作为一种面向对象语言，可以全面包容ＳＴＥＰ信息建模语言ＥＸ－ＰＲＥＳＳ的语义功能．本文论述了ＳＤＡＩ的Ｃ＋＋早、晚联编的有关概念，从ＳＤＡＩ的原始数据类型／实体数据类型／聚集数据类型的Ｃ＋＋联编、父／子类关系等方面对Ｃ＋＋晚联编展开讨论，并介绍了基于面向对象数据库ＶＥＲＳＡＮＴ进行ＳＤＡＩ／Ｃ＋＋联编实现的工作．

C++ is an object oriented language which can captures the semantics of the EXPRESS data modeling language. This paper discusses the concept and implementation of the C++ binding to SDAI, including primitives, entities, aggregates and inheritance. We give the report of its implementation based on OODBMS VERSANT as well.
