Skills | Connecting to a database Java database connection (JDBC) consists of a set of classes and interfaces written in the Java programming language. JDBC provides tools/database developers with a standard API that enables them to write database applications with a pure Java API. However, each developer's interface is not exactly the same, so the development en
