as per me the best way is to create the exact table in your database and then write a job in your server to sink up this table with the original table residing at other server and schedule it on the basis as how frequently the source (main) table is updated.

I've followed the same approach in one of our databases and it's working fine.

If your DA / DBA do a good job documenting the relationships, they would for sure use DRI in the database itself AND document the external relationship in the comment of the column !!

Not only in erwin or whatever da-document tool they use !

Any programmer studying the datamodel will benifit from that.

On the other hand .... do programmers still study the DM ?? :ermm:

Does it mean there's no tool to show that in diagram?:(

Actually no programmer is willing to review data model; unless they have to 😉 I think I'll refer to that more than anyone else :laugh:

AFAIK you dan define logical relationships in ERwin in the logical model.

But I think that will be about the only place one can do it.

That's why I suggest at least to put it in the FK-column's comment !
