WAM
provides a WAMmodel administration utility,
built with WAM itself:
WAMAdmin
is a WAM-based (hence browser based) front-end to all WAMmodel tables, and
is installed together with the WAMLibrary; it is invoked with the URL ApplicationRoot/WamLibrary/Admin.
In production environments the Admin directory should have access limited
to administrators/developers.
By
setting the “WAMmodel edit mode” to ON (bottom left of screen), the
whole application transmutes into “edit mode”, displaying an “under
construction sign” and showing orange
links to relevant WAMmodel records, and allowing interactive picking of
lookup columns. This mode is turned on by default when the WAMAdmin entry
page is displayed the first time, and can be turned off by toggling
“WAMmodel edit mode”,
For
example the following is a Northwind “Order” record shown in WAMAdmin
edit mode while the developer is choosing additional related columns to
add to WAM_LOOKUP_COLUMN:
Following
the orange links opens the WAMmodel tuple for edition with WAMAdmin; for
example, to change the “Freight” caption the developer would follow
the “WP” link and change the (meta) data in the following page:
The
following WAMmodel edition links are made available in edit mode:

Edit
(possibly creating) WAM_ROW_COLUMN record

Edit
WAM_LOOKUP_COLUMN record.

Add Lookup Column
|
Add
a new WAM_LOOKUP_COLUMN defining a lookup on the present row, using
a hierarchical menu similar to that appearing during end user list
join building

Edit
WAM_LIST record
|
|
Set default
|
Make
the current list configuration for the current user define what the
‘dbo’ user list should look like (and hence what all users will
get), in terms of WAM_LIST_COLUMNs and WAM_CRITERION. The rationale
is for the developer to configure the list as an end user would, and
then click this link.

In addition to WAMmodel editing, WAMAdmin also provides some utility
functions:
- Storing/restoring WAMmodels as a text file, as PROLOG relations; in
addition to providing a persistence mechanism external do the database,
it allows experimentation with WAMmodel transformations using AI
techniques.
- Checking consistency between the WAMmodel and the application
database, as this may be edited with another tool without WAM knowing
about it
- Report all database dependencies in custom ASPs
- Developer documentation generation
- Global WAM cache turn-off/on, so WAMmodel or database structure
changes can be seen immediately by all users
