开放式数据访问实现模式的探讨

Discussion about Realizing Pattern of Opening Data

本文对开放式数据访问模式进行了探讨,详细比较了本地数据与远程数据访问的实现模式,阐述了本地数据访问主要是利用驱动程序接口对数据库进行连接实现的,并对其主要连接方式ODBC方式、DAO方式、ADO方式等进行了分析与比较;远程网络数据访问的关键技术是"中间件"的解决方案,本文对当前几种流行的"中间件",即通用网关技术方案、ASP技术方案、应用编程接口AP工技术、JDBC技术等进行了分析与比较,最后总结出本地和远程数据访问的一般技术线路.

The paper researches access pattern of opening data, comparaing realizing pattern between local and distant data in detail, explaining local data access mainly using driver interface to carry out the connection of data bank. Moreover the paper analyzes and compares main connection models ： such as ODBC, DAO, and ADO. The key technology of internet data access is a solution design about ＂media wares＂. The paper analyzes and compares several ＂media wares＂ which are frequently used at the present. These ＂media wares＂ are as follows：interact technology design, ASP technology design, application program interface API technology, JDBC technology etc. Finally the paper summerizes general technological circuit about access between local and distant data.
