Java Database Connectivity 

Java Database Connectivity (JDBC) is a specification to access a relational database in a common and consistent way. Using JDBC, you can execute SQL statements and get results on different databases using common APIs. A database-specific driver sits between the JDBC call and the database, and it translates JDBC calls to database-vendor-specific API calls. JDBC can be used in both the presentation and business layers directly, but it is recommended to separate the database calls from both the UI and the business code. Typically, this is done by creating Data Access Objects (DAOs) that encapsulate the logic to access the database. JDBC is actually a part of Java Standard Edition. Java SE 8 contains JDBC 4.2.
