Connection Established
The JDBC API is a Java API that can access any kind of tabular data, especially data stored in a relational database.
Tabular Data : A tabular database, as the name implies is a database that is structured in a tabular form. It arranges data elements in vertical columns and horizontal rows. Each cell is formed by the intersection of a column and row.
JDBC helps you to write Java applications that manage these three programming activities:
1.Connect to a data source, like a database
2.Send queries and update statements to the database
3.Retrieve and process the results received from the database in answer to your query
Connection Interface:
A Connection is a session between a Java application and a database. The Connection interface is a factory of Statement, PreparedStatement, and DatabaseMetaData i.e. object of Connection can be used to get the object of Statement and DatabaseMetaData. The Connection interface provides many methods for transaction management like commit(), rollback(), etc.
