Advanced Java Interview Question:

Why use a datasource when you can directly specify a connection details? (in a J2EE application)?

Submitted by: Administrator

Because, it would be really difficult to specify the connection details in every method that access the database. Instead, if we create a data source, it can be used to connect to the database in every method we want.

The Datasource objects handles connection pooling which is a much more efficient way to access the database than using the same connection/getting a new one.
