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

In addition, sun's ODBC-JDBC bridge is not multi-threaded, that is, it is not suitable for enterprise applications that require concurrent

To describe JNDI, for example, when obtaining a data source, the JNDI address can be written in either of the following ways:A: Java: COMP/ENV/jdbc/testdsB: JDBC/testds The configuration methods are also different. The first method is a method that facilitates program transplantation or migration. Its implementation is
