Deploying a DataSource object consists of three tasks: The system administrator needs to deploy DataSource objects so that The Coffee Break's programming team can start using them. Client computers making requests are the first tier. The owner now has a three-tier architecture, with a new EJB application server and JDBC driver in the middle tier and the two DBMS servers as the third tier.

Many JDBC drivers are available that are compatible with the recently purchased EJB server. The owner has purchased the most recent JDBC driver and an EJB application server that works with it to be able to use distributed transactions and get the increased performance that comes with connection pooling. The chain owner has reconfigured the computer system to serve the new, larger customer base. This means that the owner will want to be able to write distributed transactions that use both the old DBMS server and the new one. In addition, the owner now has a second DBMS that contains data for the recently acquired coffee roasting company. With connection pooling, a pool of connections can be used over and over again, avoiding the expense of creating a new connection for every database access. Opening and closing connections involves a great deal of overhead, and the owner anticipates that this online ordering system will necessitate a sizable number of queries and updates. With the large amount of online business expected, the owner will definitely need connection pooling. Suppose that the owner of the thriving chain of The Coffee Break shops, from the previous examples, has decided to expand further by selling coffee over the Internet. For example, a DataSource class provided by an EJB vendor almost always supports both connection pooling and distributed transactions. The sample for this tutorial requires compact profile 3 or greater.ДЄ DataSource class that supports distributed transactions typically also implements support for connection pooling. If your client runs on Java 8 compact profile 2, then the Java DB JDBC driver is .BasicClientDataSource40. For example, the Java DB JDBC driver includes the implementation .ClientDataSource and for MySQL, 2.optional.MysqlDataSource.

A DataSource implementation that supports distributed transactions produces Connection objects that can be used in a distributed transaction, that is, a transaction that accesses two or more DBMS servers.ДЄ JDBC driver should include at least a basic DataSource implementation.

A DataSource implementation that supports connection pooling produces Connection objects that participate in connection pooling, that is, connections that can be recycled.

A basic DataSource implementation produces standard Connection objects that are not pooled or used in a distributed transaction.

It can be implemented in three different ways: The DataSource interface is implemented by a driver vendor. If a company uses more than one data source, it will deploy a separate DataSource object for each of them. A DataSource object represents a particular DBMS or some other data source, such as a file. Objects instantiated by classes that implement the DataSource represent a particular DBMS or some other data source, such as a file.

This section shows you how to use a DataSource object to get a connection to your data source, which is the preferred way. In Establishing a Connection, you learned how to get a connection using the DriverManager class. Using DataSource Objects to Get a Connection Using Connections for Distributed Transactions.Deploying Other DataSource Implementations.Using DataSource Objects to Get Connections.As a result, most of this section is devoted to showing how a system administrator sets up the environment so that programmers can use a DataSource object to get connections.

The work performed to deploy the classes that make these operations possible, which a system administrator usually does with a tool (such as Apache Tomcat or Oracle WebLogic Server), varies with the type of DataSource object that is being deployed.

Both of these involve very few code changes in your JDBC application. This section shows you how to get a connection using the DataSource interface and how to use distributed transactions and connection pooling. In particular, it is integral to Enterprise JavaBeans (EJB) technology. This functionality is essential for enterprise database computing. In addition to their other advantages, which will be explained later, DataSource objects can provide connection pooling and distributed transactions. This section covers DataSource objects, which are the preferred means of getting a connection to a data source.
