Describe how the JDBC application works

A JDBC application may be divided into two layers:

• Driver layer

• Application layer

• The Driver layer consists of DriverManager class & the JDBC drivers.

• The Application layer begins after putting a request to the DriverManager for the connection.

• An appropriate driver is chosen and used for establishing the connection. 

• This connection is linked to the application layer.

• The application needs the connection for creating the Statement kind of objects by which the results are obtained.
