基于ATML标准的测试系统数据模型设计

Automatic Test System DataModel Design Based on ATML

为实现TPS与测试系统硬件的隔离,提高TPS的通用性与可扩展性,建立了以硬件设备属性为基础的测试系统数据模型;该测试系统数据模型根据ATML标准进行设计,描述测试系统的硬件信息及在测试过程中记录的数据,实现了测试系统内部各组件之间、各测试程序之间数据信息的无缝连接与共享;通过C#编写了转换方法,可以实现数据由传统的关系型数据库形式转化为XML格式,提高了数据模型的通用性;经检验表明,该数据模型可有效提高TPS的可扩展性,降低开发成本。

For improving the interchangeability and extensibility of TPS,ATS data model is presented.The data model describes ATS hardware information and records all kinds of data in test process.And it is designed according to ATML standard and realizes data shares in ATS.At the same time,a public method programmed by C# is introduced,which can translate traditional relationship data into XML format.The evaluation results proved that it is effective,which reduces TPS development cycle and improves TPS extensibility.
