Define maps
This section describes how to define maps with the High-Performance Loader (HPL). It also describes the options that are available for defining maps.
- Load and unload maps
You can use the ipload utility to build a map. A map specifies the relationship between the fields of a data file and the columns of a database. - Unload maps
An unload map associates columns extracted from a database by a query with the fields in a data-file record. You can create an unload map from the Load Job window or from the Components menu of the HPL main window. After you define an unload map, you use it with the Unload Job window or the onpload utility. - Mapping options
The mapping options define conversions that onpload applies to the data before it inserts the data into the database (for a load job) or into the data file (for an unload job). These conversions can include case conversion, text justification, data masking through picture strings, default values, and fill characters. The mapping options also allow you to replace imported data with data from other database tables. - Editing options
This section discusses specialized options in the Map-Definition window. - Map Views window
You can display a list of the components that are associated with a database in a specific project from the Map Views window. You can also create or edit a map.
