DB2 graphic QMF Version 8

Purpose

Select File -->New --> Map to visualize query results in the map form using a map application.

The Map option enables you to view data from DB2 in a map rather than through conventional means such as in a chart, report, or browser. Only tables having a column with type of GEO can be rendered as a map in QMF for Windows.

The maps, composed of layers of spatial data, enable you to visualize connections between tables, such as the geographic distribution of customers for a branch of a bank. Rather than submitting a query and creating a report, you can specify the layers (for example, a branch layer and a customer layer) and view the clustering.

Two things happen when you select the Map option:

  1. Information will be gathered for the location, shape of, and relationships among business data and geographic data, including map data.
  2. This information will be stored in industry standard files known as shape files (.spm).

With shape files, spatial data can be interchanged with other applications or databases that recognize this format.

An error message will be sent if the Map option is selected for a table that does not contain Geo data.
