Label:Brief introduction JDBC (Java Data Base Connectivity,java database connection), an API consisting of some interfaces and classes. Enables programmers to connect to the database through this API interface and use Structured Query language (i.e. SQL) to complete the lookup and update of the database. (SQL is often pronounced as "sequel", which is the industry standard for database access.) JDBC
