众所周知,软件开发离不开对数据的访问。数据访问在整个软件开发的三层构架中属于数据层,是其它两层的基础。没有了它,存储的数据变的毫无意义。与此同时,数据访问的效率将直接影响到软件的质量。一个数据访问缓慢的系统是客户无法容忍的。一个好的系统必然有一个高效的数据访问方法。由此可见,数据访问在软件开发过程中是非常重要的。如果能统一对数据的访问方法,那么一切有关数据访问方面的问题都可以得到解决。我的系统将可以面向所有的数据源,甚至是未来将会出现的数据源。 预期结果 实现对SQLServer,ODBC,OLEDB数据源以及工业中的Citect,IFix监控软件数据源的统一访问。 开发环境: Microsoft Windows2000开发平台 开发工具: Microsoft Visual C++.NET 数据源: Microsoft SQLServer2000,Citect,Ifix,ODBC 文件说明: DAServer2.dll是一个统一数据访问平台。提供OLEDB标准接口。用户可对其进行访问。 SQLServerProvider.dll是针对SQLServer数据源的提供程序。 config.ini是系统配置文件。- Data access in the entire software development fr a mework is a three-tier data layer, the other is a two-tier basis. Without it, the data storage change meaningless. Meanwhile, the efficiency of data access will directly affect the quality of the software. A slow data access system is the customer can not be tolerated. A good system will be an efficient data access methods. This shows that access to data in the software development process is very important. If reunification of data access methods, all aspects of the data access problems can be resolved. My system will be open to all sources of data, or even the future there will be data sources. To achieve the expected results of SQLServer, ODBC, OLEDB data sources and the industrial Citect, Ifix monitoring software data sources unified a
