摘要: 针对Epicentre数据模型没有提供对自行构筑应用数据模型投影支持的问题,在充分研究Epicentre数据模型和POSC投影理论的基础上,结合中石化数据模型SPDM1.0的自身特点,开发了一套投影辅助工具,完成了SPDM1.0逻辑模型与物理模型之间的数据转换。

Abstract: Aiming at the problem that Epicenter data model doesn’t provide a projection support for their own application data model, in the full of studying Epicenter data model and the theory of projection of POSC, based on combining characteristics of Sinopec’s SPDM1.0, this paper develops a projection tool to complete data conversion between SPDM1.0 logical model and physical model.

Key words: POSC, Epicentre, SPDM 1.0, projection tool, logical data model
