摘　　要：中标麒麟操作系统是基于Linux内核开发出来的具有较高安全性的国产化操作系统,需要一套独立的数据访问机制支持对达梦数据库的访问,并能够保证数据应用的安全可靠。基于系统底层Unix ODBC驱动封装的ODBC数据访问接口提供了对达梦数据库最全面的访问应用,支持Blob类型数据存储和操作,并保证数据读取和操作响应时间较短,从而满足指挥信息系统应用中对大对象数据的实时访问要求。该接口实现了数据库服务器端与客户端之间的数据共享与同步功能,满足了应用端对达梦数据库实时存储、增加、修改、删除和查询等要求,减轻了软件开发人员跨平台远程访问数据库的复杂度和工作量,实现了国产化平台访问数据库的最优、最科学应用,保证试验人员快速获取实时可靠的应用数据。The NeOKylin is an operating system of domestic production based on the Kylin Linux kernel development with high security and requires a set of independent data access mechanism to reach the access of Dream Database, and to ensure the safe and reliable data applications. The ODBC data access interface based on the underlying UnixODBC driver encapsulation provides the most comprehensive access to Dream Database, supports data storage and operation of Blob, and ensures data reading and shorter operational response time, thereby meeting the real-time access requirements of large object in command information system applications. The interface realizes the data sharing and synchronization between the database server and client, meets the requirements such as real-time storage, addition ,modi- fication,deletion and query of the database by the application end,reduces the complexity and workload of database accessing in cross- platform for software development staffs, and achieves the best and most scientific applications of database accessing with platform of do- mestic production,so as to ensure that test personnel can quickly access to real-time and reliable application data.
