1.5 Columns
Designed like the 'Tables' tab but this one allows you to search for a character string in the column names in the model that you have selected.  That is all thousands of the columns in the data model.  In this example, I used the index and went to the bottom of the list to see what columns are in the data model.

And you can select to search for columns by typing in the word (or portion there of) to zero in on what you are looking for.  As in this example:

Okay, so I was looking for 'loo' and it came up with columns with 'fLOOr'.  So, once you have found the column(s) you want, select one and a search will done of the database to find all tables with that column in it.  A screen like this will show up:

This screen shows that there are three tables with 'DERRICK_FLOOR_ELEV' as a column.  I have to admit, that two tables did not surprise me, but WELL_SUPPORT_FACILITY.  That's new.  I guess I should check it out and on it goes.
