How to create interface where you can view metadata of several databases

Question

How to create interface where we can view metadata of several databases:
Oracle Apex should display metadata of this particular DB (later on we can include multiple DB’s)
          a. Report should first display DB name
          b. When clicked on DB name, should display 3 schemas
          c. When clicked on 1 schema, should display tables – when clicked on each table,
          should display various column names and its corresponding metadata.
          (similarly for other schema’s also)
          d. In short, it should be like a drill down report.
Help required for craeting like above.
Appreciate your help.

Answer 1

I did something similar a while back. I had an application reading from multiple schema's for reporting purposes..IN that case atleast we just would build the selects using a function reurning SQL select, so that we could have an application item with the selected schema they wanted to use to build into the select returned...
For forms, that would be an interesting idea, don't know how you can dynamically change the table owner name, since it is a drop down control in development..
