Database access
It is very likely that the Call Center Desktop will have to access data residing in a relational database, such as IBM DB2 Universal Database™.
Java SE 6.0 includes several integration technologies:
| JDBC is the Java standard technology for accessing data stores.
|
|
| Java Remote Method Invocation (RMI) is the standard way of enabling remote access to objects within Java.
|
|
| Java Naming and Directory Interface (JNDI) is the standard Java interface for naming and directory services.
|
|
| Java IDL is the Java implementation of the Interface Definition Language (IDL) for the Common Object Request Broker Architecture (CORBA), allowing Java programs to access objects hosted on CORBA servers.

We focus on the Java DataBase Connectivity (JDBC) technology in this section.
