I created two tables in google appengine datastore using JPA.

Table1:

*groupname pk

*groupid

*groupdesc

*emailper

Table2:

*groupname

*memberid

*membername

My constraint is if i enter data into table2 it check whether group already exists or not in table.If exists than only it store the data into table .How to solve this?
