摘要
为提高水调系统数据访问效率,设计和实现了一种数据库中间件,以此屏蔽了水调应用软件复杂的数据访问过程。文中介绍了该中间件的体系结构,阐述了实现过程中应用的关键技术(数据库连接池、多线程、ODBC/UNIX ODBC、存储顺序转换),并给出了此软件在三峡水库调度系统中的应用实例。
To improve the efficiency of data access in hydrological systems, a cross-platform database middleware system is designed and realized which hides the process of database access for automatic hydrological applications. The architecture of the middleware is discussed. Some details about critical technologies are offered, including database connection pool, multithreading, ODBC/UNIX ODBC, storages order change. An example of application of the middleware to the Three Gorges reservoir dispatching automation system is also provided.
