關聯式資源配接器和 JCA
資源配接器是一個系統層次的軟體驅動程式,Java™ 應用程式利用它來連接企業資訊系統 (EIS)。 資源配接器插入應用程式伺服器,並在 EIS、應用程式伺服器和企業應用程式之間提供網路功能。JDBC providers
Installed applications use JDBC providers to interact with relational databases.Data sources
Installed applications use a data source to obtain connections to a relational database. A data source is analogous to the Java Platform, Enterprise Edition (Java EE) Connector Architecture (JCA) connection factory, which provides connectivity to other types of enterprise information systems (EIS).Data access beans
Data access beans provide a rich set of features and function, while hiding much of the complexity associated with accessing relational databases.Connection management architecture
The connection management architecture for both relational and procedural access to enterprise information systems (EIS) is based on the Java Platform, Enterprise Edition (Java EE) Connector Architecture (JCA) specification. The Connection Manager (CM), which pools and manages connections within an application server, is capable of managing connections obtained through both resource adapters (RAs) defined by the JCA specification, and data sources defined by the Java Database Connectivity (JDBC) 2.0 (and later) Extensions specification.Service Data Objects: Resources for learning
Use the following links to find relevant supplemental information about the service data object and various other functions that can be used with it. The information resides on IBM® and non-IBM Internet sites, whose sponsors control the technical accuracy of the information.
