Configure a New Custom Data Source
When you open a custom data source, the display on the right of the Studio window includes several tabs:
Configuration—The contents of this tab are different from the Configuration tab for built-in data sources.
Overrides—This tab is not present in the display for built-in data sources.
Cardinality Statistics—The contents of this tab are the same as for a built-in data source.
Re-Introspection—The contents of this tab are the same as for a built-in data source.
Introspection Report—The contents of this tab are the same as for a built-in data source.
Relationship Discovery—The contents of this tab are the same as for a built-in data source.
Info—The contents of this tab are the same as for a built-in data source, except the tab has no Cluster Health Monitoring or Resource Capabilities section.
For a description of the tabs for built-in data sources, refer to the three Configuring Data Sources chapters in the TDV User Guide.
Info Tab
The Info tab is where you specify the properties for which the adapter requires values from the data source, such as connection information. It has two subtabs, Basic and Advanced.
This is sometimes called the main data source UI or simply the data source UI.
Overrides Tab
The Overrides tab appears whenever an adapter is enabled.
NOTE: Under certain rare circumstances a property might display different values on the Info and Overrides tabs. The value displayed on the Overrides tab is the one that will be used.
In the Search for properties to override section, you can search in one of two ways:
Begin typing the name of a property. Once you have typed at least two characters, a drop-down list displays all properties with names that contain the string you typed.
Type * (an asterisk) for the full list of available properties.
When you see the property you want to override, you can select it from the drop-down list; it then appears on the subtab for the group to which it belongs, and disappears from the main list.
After adding a property, you can redisplay the list of properties still available by again placing the cursor in the search field next to the asterisk.
The Overrides tab contains several subtabs, each with content that varies with the way the extension adapter was configured:
Simple Properties Tabs
Data Type Mappings Tab
Clauses Tab
Operators Tab
Functions Tab
Adapter configuration defines which properties are available for selection on the Overrides tab, as explained in these five sections.
