摘要: 组成作战系统的各设备所需数据种类繁多,数据访问各自为政、效率低、耦合紧密。为此,提出一种基于通信中间件的数据访问机制,设计该机制的体系结构,基于订阅/发布模式实现快速、无连接的数据访问,采用规则转换自动产生SQL语句,从而达到数据访问的最大松耦合,同时阐述机制的数据访问流程,并在某作战仿真系统中验证该机制的有效性。

Abstract: The equipments of the combat system need many types of data, and the traditional tight coupling data access are not efficienct enough. A new data access mechanism based on communication middleware is proposed. The architecture of the mechanism is designed. Fast and non-connected data access is achieved by using subscribe/publish schema. A set of conversion rules is adopted to generate SQL statements to achieve the loosely coupling data access. The access flow of the mechanism is expatiated. The mechanism is implemented and certificated in a combat simulation environment.
