| 摘 要： | 文章提出了一种数据库访问柔性中间件的概念.它的主要作用在于,根据定义的语法规则库,对应用系统的数据库请求进行词法分析和语法分析,并在此基础上,把基于某种数据库管理系统所开发的应用系统要来访问其他数据库管理系统时,所有SQL请求、调用机制、存储过程调用、数据类型等的差异全部在柔性中间件解决,从而实现应用系统的平滑移植.

| Abstract: | With security needing of information and state database' mature, they will be applied in application. It is difficulty to develop state database' application under overseas database' monopolization, so it is important to replant applied system on state database. In order to settle the problem we bring forward a flexible middleware of accessing database. It main function is that it analyses accidence and grammar of applied system' database request, and resolves all problem of SQL?transfer mechanism?transfer producer?data type etc. at last the applied system can run on the other database successfully. |
