Background documentation Data Access and Method Execution  Locate the document in its SAP Library structure

In addition to metadata retrieval, the connector framework provides additional features for data access and method execution.

The connector allows data access with following functions:

Feature

Description

Provided by

Native queries

(INativeQuery)

The connector accepts commands and queries stated in the application language, for example, SQL and MDX. The returned data type is Java.lang.Object and the connector passes it on to the user application as it is, without parsing or interpretation.

Connector Framework

Function or interaction

(IInteraction)

The connector invokes a given function, that exists in the application as follows:

Every parameter supports data type, owner, valid values, in/out direction, default value (if optional), and so on. See section Interface ConnectionSpec for more details.

JCA

Native API Access

(INative)

The native module wraps the interface visible to the application. The connector returns a reference to a requested native interface and from this point on, the user of the connector interacts with the EIS directly through that interface.

The Java Connector client (JCO) service is an example of this. The JCO client service implements the connectivity to SAP back-end systems. The JCO client service gets an SAP back-end system connection from of the connector framework first and then calls for the JCO interface to get a native function.

An example of this for a relational database management system would be java.sql.Connection.
