<p>Various enterprise information systems use different methods for storing data. These back end data stores may be relational databases, procedural transaction programs, or object-oriented databases. WebSphere Application Server - Express provides several options for accessing an information system's back end data store:</p>
|
|
|
|
<ul>
|
|
<li>Program directly to the database through the JDBC 2.0 Optional Package API.</li>
|
|
<li>Program to the procedural back end transaction through various J2EE Connector Architecture (JCA) 1.0 compliant connectors.</li>
|
|
<li>Program servlets to indirectly access the back end store through either the JDBC API or JCA compliant connectors.</li>
|
|
<li>Use IBM data access beans, which also use the JDBC API, but give you additional ability to manipulate result sets.</li>
|
|
</ul>
