6.14 Specifying Alias in Connector

Alias refers to an assumed name or alternative name assigned to an EDD as you define connectors, much like table aliases used in SQL statements. Aliases allow an EDD to be referred in multiple joins, lookups, or both, within the same connector definition, each in a distinct context.

Aliases are automatically initiated by Data Services as and when required while defining connectors.

The following scenario explains the mechanism:

1. Drag and drop an EDD more than once, for use in separate joins or looks-up, on the New Connector canvas. Data Services initiates the specification of an alias by displaying the Specify Alias dialog box.
2. Enter a name of your choice under Alias Name and click OK.
   Note that the Alias Names must be unique within a connector.
