How to Navigate
The menu on the left is organized by modules. Each module contains a set of tables that comprises a portion of the PPDM37 data model. If you click on the module name the menu will expand to show the constituent tables and provide a description of the module.
If you click on table name on the left menu, you will get the table definition and other associated data. You can view column definitions and constraint information by mosing over the column name or constraint name. You can navigate between table definitions by selecting referenced table links.
If you dont know the module or simply want to view one specific table, there is a drop down box of all the tables that will display the table definition when selected.
Viewing Diagrams
There are 100 diagrams that help show relationships between tables within modules. You may view these by navigating to the bottom of the left hand menu and by expanding the Diagrams menu item. Alternatively, you can link to any diagram associated with a specific table by mousing over the "View Diagrams" link that is provided on each table definition page and selecting a diagram from the list.
When viewing the diagrams, there are three image formats to choose from. The following describes each format.
SVG
This is a relatively new XML based image technology viewable in Internet Explorer 6.0 with the Adobe plugin. This format provides an excellent image for viewing but may cause problems. Select this format omly if you are sure that you have Internet Explorer and the Adobe plugin set up properly.
HTML (PNG + image map)
This image format should be available to most browsers. The diagram should be viewed at full size for the best resolution. Each diagram has an associated image map that allows you to link back to table definitions based on the table identified in the diagram. Note that navigational capabilities (such as panning and zooming) are more limited in this format than SVG or PDF.
Most everyone is familiar with PDF. You will need the Adobe plug-in installed to view this format. PDF's provide an excellent source image to print from, but often take more time to load into the browser.
