1. 跨语言db api兼容性。。
方便源码移植。。需要实现常用的 jdbc odbc c_api接口。。总共约好几百个个方法函数（预估，因为jdbc方法数量与属性暂时未统计）
2. 目前访问数据库的接口很多。比较常用的jdbc odbc 以及c api （php用此接口），共约101个类+128个c函数

2.2. Odbc api数量：：约78个，odbc是个非oo的api
2.3. C api （mysql ）： 约50个。。
这些开发包支持两种模式的数据库开发：预编译的嵌入模式（例如Oracle的ProC，SQL Server的ESQL）和API调用（例如Oracle的OCI）。

3. ADO、OLEDB、ODBC之间的关系图
Oracle的OCI是一个非常优秀的C语言开发包，在ODBC中就在很多地方参照了OCI的设计。
下面是微软提出的所有连接方式:
ODBC（Open DataBase Connectivity）开放数据库互联。是由微软主导的数据库链接标准，只支持关系型数据库。
DAO（Data Access Object）数据访问对象。不提供远程访问功能。
RDO（Remote Data Object）远程数据对象。速度快，支持SQL Server存储过程。
OLEDB（Object Linking and Embedding DataBase）对象链接和嵌入数据库。
ADO（ActiveX Data Object）ActiveX数据对象。
使用中，我们一般用OLE-DB和ADO替代DAO和RDO,DAO和RDO我也没用过，所以下面主要记录下ADO、OLEDB、ODBC之间的关系。

接口）。这些API利用 SQL来完成其大部
4. Jdbc Package java.sql Jdbc api数量 约60个类..java.sql包下面的。。
