java - Why drivers are required for JDBC-ODBC? -


i having little confusion of have studied. have studied drivers software programs required interact external hardware devices printers,mouse,mobiles etc. when connect odbc or jdbc in java,it requires specify drivers.

so why need specify drivers since our database( oracle dbc ) software , not hardware.

your understanding of driver not correct. driver not hardware external but driver needed special cases of software interaction. in case driver used access filesystem system alone wouldn't able understand. driver used connect database , able interact it.

the exact definition is: java database connectivity (jdbc) application programming interface (api) programming language java, defines how client may access database. (taken wikipedia)
