DataSource Processor

The DataSource processor forms the input to the designer environment. This processor, provides a diagrammatic representation of the different types of data sources available in the data designer.

The data from another DataSource (it could be a primitive data source like JDBC or XML, or another Composite) can be extracted using this processor. It can be created in one of two ways:

The editable properties are shown in Figure 4.3, “DataSource Wizard”.

The data sources in the repository are listed in the DataSource window from which a data source can be selected.

The name of the fields and the corresponding data type of the selected data source are displayed in the schema tab. The unwanted fields can be discarded by selecting the appropriate check box present in the Discard column. Discarding fields reduces the amount of memory needed to process the data.

Click the Next button to see any editable property values. Property values can be assigned here for any dynamic parameters in the selected data source. Refer to Appendix A, Dynamic Parameters for a detailed explanation on passing parameter values.

Note

Right-clicking on the Datasource processor shows the options available, one of which is to open the datasource. User will then be able to open the datasource directly instead of searching for it in the repository.
