摘要：

依据网络化自动测试系统(NATS)存储和查询功能对数据模型的要求，比较扩展关系数据模型、语义数据模型和面向对象数据模型等多媒体数据模型实现方式的优缺点，提出数据库设计的基本框架为静态数据信息采用关系型数据模型，非结构化的多媒体数据信息采用对象-关系模型与文件系统结合的方式，并完成NATS的总体设计。实验结果证明了该框架的有效性。

Abstract:

According to the require of data model based on the memory and query function of Networked Automatic Test System(NATS), this paper compares the merits and defects from different data models such as the extended relational model, semantic data model and object oriented data model, proposes the basic frame of the database which is that static data information adopts relational data model and unstructured multimedia data adopts a method combing object-relational model with file system, and implements the total design of NATS. Experimental result shows the validity of the frame.
