Establish relation between Parameter in one table with parameter in another table.
e.g
TABLE ABC (param,val)
insert ABC (paramA, 30)
TABLE BCD (param,val)
insert BCD (paramB,50)
Now there should be mechanism to create relation between two parameters with links so that when I modify paramA, paramB also get modified with values predefined/formula.
It should also enable us to create cascade affect across multiple tables when parameter of one table is modified
