Registering Data Sources

Preparing to Create ODDs

Before you create an ODD Group and its associated ODDs, you must first do some preparation, which is summarized next:

Hierarchy of objects	The Data Warehouse Environment that will contain the ODD Group and its ODDs must exist.
Global metadata	Create at least some of the appropriate host definitions, SAS library definitions, and other global metadata items that your ODDs require, as described in the Maintaining Global Metadata.
Input source(s)	Determine which input sources(s) to use for each ODD. Identify the host and physical path for each input source.
Output target	Determine how many ODDs you need. Your Process Flows might be easier to understand and manage if you have one ODD for each of the main data sources identified in your project plan.
