Reverse engineering a 10 year old datamodel with 600 tables results in a messy circuit diagram.

What I really need is to choose a source table central to the main themes such as ORDER_LINE_ITEM and then have the ERD tool pull in tables to the diagram that are 1,2,3 foreign key relations away.

I once used a tool that would let me 'throttle' the size of tables involved like this but it was for MS_SQL.

Does such a tool exist ?

ER/Studio seemed to have that 'LEVEL' facility for child or parent Fkey releated entities in a Subdatamodel but it never actually added them in automatically.

SQL Developer from Oracle is like the sqlplus command history with a depth of '1'. You can auto pull in children or parents but only one ring or level away from the table your working with.
