project description one

这是我在javaeetutorial5 中看到的有关资料。分析一下。那些我们可能经常用到。嘿嘿

Duke’s Bank has two clients:

an application client used by administrators to manage customers and accounts,

and a web client used by customers to access account histories and perform transactions.

The web client is built using JavaServer Faces technology.

The clients access the customer, account, and transaction information maintained in a database through enterprise beans.

The Duke’s Bank application demonstrates the way that many of the component technologies presented in this tutorial (enterprise beans, application clients, and web components) are applied to provide a simple but functional application.

 

Let’s take a closer look at the access paths between the clients, enterprise beans, and database tables.

The end-user clients (web and application clients) access only the session beans.

Within the enterprise bean tier, the session beans use Java Persistence entities.

On the back end of the application, the entities access the database tables that store the entity states.
