Steps for connecting to the database using JDBC:-

#1 Using Driver Manager:-
a.Load the driver class using class.forName(driverclass) and class.forName() loads the driver class and passes the control to DriverManager class
b.DriverManager.getConnection() creates the connection to the databse


#2 Using DataSource:-
DataSource is used instead of DriverManager in Distributed Environment with the help of JNDI.
a) Use JNDI to lookup the DataSource from Naming service server.
b) DataSource.getConnection method will return Connection object to the database

JDBC providers:it is the actual implementation of driver class to access the different database types.
Data source: It is associated with JDBC provider to get connected with the database.It is normally use for connection purpose.
