基于Unix电网集成数据管理环境设计和实现

面向电网数据一体化管理的需求，设计并实现了基于Unix平台的电网数据集成管理环境，它是可视化、面向对象及开放的。将SQL数据库与实时数据库的访问接口封装成开放式数据对象的中间件；根据电网数据的逻辑限制和相互依赖关系定义数据模板，通过模板访问数据库时审核数据有效性；设计并实现树、表单等高级控件以实现图形化管理数据；资源文件与数据库模板对应实现无编程的设备参数管理界面；分解用户指令为语素的引导型查询模型。它不依赖于电网特性，可在更广泛的领域中应用。

Integrated Data Management Environment on Unix

In order to meet the requirement of power network data management,an integrated data management environment on Unix is presented,which is visualized, object oriented and open. The APIs of SQL database and real time database are encapsulated into an agency called open data object and the data templates are defined according to the logic limitation and interrelation of power network data.The data are validated when the database is accessed through template and the advanced widgets,such as list,table,tree,etc.,are developed to realize the visual data management.The source files are corresponding to database templates to realize the parameter management without programming.The guiding query mode is used to dissolve the user instruction into semantic elements.Because it does not depend on power network property,it can be applied in other domains.
