一体化仿真训练系统数据访问中间件关键技术研究

为了支持一体化训练仿真系统的数据访问和维护,提出了面向对象的分布式数据访问中间件,设计了数据访问中间件的体系结构,使用数据字典实现各分系统语义领域的统一,基于元数据描述数据对象关系模型和数据分布,阐明了中间件的数据访问流程,解决了远程数据访问过程、对异构数据模型的支持和分布式事务处理方法等关键技术,说明了中间件维护控制过程和对数据集的处理方法。

Key Technology Research on Data Middleware of Integrated Simulation Exercises System

In order to sustain the integration exercise simulation system, an Object-Oriented distributing data middleware was put forward, the architecture of the data middleware was designed, the data criterion the consistency of semantic of the sub-systems was implemented by data dictionary, the object-relation data model and data-distributing were described using metadata, the access flow of the data middleware was expatiated, and the remote data access course, isomerous data model, distributed data transaction were introduced, the control and maintain process and the managing method of data collection were showed.
