Hi All,
I have the following tables.
tablename : versions tablename :
applicationmanager tablename : applications
versionnumber-string versionnumber -
string applicationnumber - integer
applicationnumber - integer other details
tablename : profilemanager tablename : profiles
versionnumber : string versionnumber : string
profilename : string profilename : string
applicationnumber : integer
otherdetails
Primary key :
---------------
(1) versions : versionnumber
(2) applicationmanager : versionnumber, applicationnumber
(3) applications : applicationnumber
(4) profilemanager : veriosnnumber, profilename, applicationnumber
(5) profiles : versionnumber, profilename
Relations :
-----------
(1) versionnumber of 'applicationmanager' referes to versionnumber of
'versions' table.
(2) applicationnumber of 'applicationmanager' referes to
applicationnumber of 'applications' table.
(3) versionnumber and applicationnumber of 'profilemanager' referes
to versionnumber and applicationnumber of 'applicationmanager'.
(4) versionnumber and profilename of 'profilemanager' referes ot
versionnumber and profilename of 'profiles'.
(5) versionnumber of 'profiles' referes to versionnumber of
'versions'.
In the above design I can able to see duplication of data in all the
tables. If I take out a id out of all these tables to make reference, is
that problem will solve. Is that is
a correct approach.
Can any one help me.
regards,
Deepa K
