How to create Master database table in sqlserver 2008.

you can make relations between tables by the explorer window on the left of the screen by choosing the tables you want but you must take care of the logic relation between relative data in all tables to the master table by code and making a primary row on the master table and a secondry  row on the child table that is related by code to each other 

i hope i hit the right answer

two ways to solved this problem, you can break the relation with parent child or you add the following Cascade option enable in Tables, you removed it.
i think your problem will solved

Hello, the concept of inheritance from the object oriented programming does not apply in the SQL programming ...
I think this is the problem.
I am not aware to be possible in SQL to do the things you need automatically.
The only thing that I can suggest is that you have to use a trigger in order to propagate the changes that were made.

Create After Update, After Delete trigger in Master table and writer necessary SQL scripts in triggers to do changes in child tables.

You can use replication (Snapshot or Transaction Replication)

or you can use triggers (After insert / After update / After delete)
