call to a specific database(2) An ODBC-based application's operations on the database do not depend on any DBMS (Database manager System) that does not work directly with the DBMS. All of the databases operations are done by the corresponding DBMS's ODBC driver. This means that either FoxPro, Access, MySQL, or Oracle databases are accessible using the ODBC API. This shows that the biggest advantage of ODBC is the ability to handle all databases in a

The drivers provided by the database vendors, such as MySQL and Oracle, can be identified and work properly if they meet the requirements of the driver manager. Therefore, JDBC is not restricted by database vendors.JDBC APIs can be used as links to connect Java applications to various relational databases, which brings convenience and negat
