Components of the Unload Job

Before you can unload data, you must first define the following components of the unload job:

• The device array that receives the unloaded data

  See Defining Device Arrays.

• The format that describes the organization of the data file into which you are unloading data

  See Defining Formats.

• The query that extracts the desired records from the database

  See Defining Queries.

• The unload map that describes the relationship between the columns of a database table and the fields of the data-file record

  The map also specifies any necessary data translations, such as case conversion and justification. See Defining Maps.

You can define these components in the following ways:

• Define each component from the Unload Job window.
• Define each component individually from the Components menu.
• Use the Generate Job option from the Components menu.
• Use the Generate button in the Unload Job window.

For information about how to use the generate options, see Generate Options.
