JDBC (Java Data Base Connectivity,java database connection) is a Java API for executing SQL statements that provides unified access to a variety of relational databases, consisting of a set of classes and interfaces written in the Java language.

I. overview 1.1JDBC concept JDBC (JavaDatabaseConnectivity) is a user interface for connecting to the database provided by Java to support SQL functions. JDBC includes a set of APIS (Java) language-written interfaces and classes are independent of
