Network Deployment (Distributed operating systems), v8.0 > Migration and coexistence
Migrate Data access resources
Enterprise information systems (EIS) use backend data stores such as...
- relational databases
- procedural transaction programs
- object-oriented databases
Data is accessed using...
- Program directly to the database through the JDBC v2, v3, or v4 4.0 API.
- Program procedural backend transaction through various J2EE JCA 1.0 or 1.5 compliant connectors.
- Program bean-managed persistence that accesses the backend store through either JDBC API or JCA-compliant connectors.
- Use container-managed persistence (CMP) beans.
- Use IBM data access beans, which use the JDBC API and hide complexity.
Service Data Objects (SDO) offer universal abstraction for messages and data, allowing manipulation in terms of XML documents or Java objects. For programmers, SDOs eliminate the complexity of the underlying data access technology such as, JDBC, RMI/IIOP, JAX-RPC, and JMS, and message transport technology such as, java.io.Serializable, DOM Objects, SOAP, and JMS.
