What are basic steps in writing a Java program using JDBC ?


Steps in Java application to access database :

1. Load JDBC driver
    This 
RDBMS specific driver actually communicates with the database.
    Not applicable for JDBC 4.0 as driver is automatically loaded.

2. Open Connection
    Connection is used to send SQL statements and get results back.

3. Create Statement
    JDBC Statement object contains SQL query.

4. Execute statement
    Executes statement which returns resultset(s)
    ResultSet contains the tuples of database table as a result of SQL query.

5. Process ResultSet

6. Close the connection
