The purpose of this tutorial is to use a separate layer written in Java to access the tables in the database, which is often called the data Access Layer (DAL) The biggest advantage of using the DAL is that it simplifies access to the database by using several methods like insert () and find (), rather than always doing a link first and then executing some queries. The layer handles all database-related calls and queries internally. Creating a Data

A simple record of how to use the Synchronized keyword in java.
