before i had a big database more than 90GB and it's growing very sharp so what i did is to create a summary database that gonna hold some aggregation and i create also three tables that gonna hold the data, on will hold the data for the last three months (very detailed information) one between 3 months and a year(less detailed) and the last one older than a year(less less detailed) these are the company requirement i'm working with.
then i transfer the data to the new tables with stored procedures.
now my question is: do i need to create a view for these three tables? and if yes how should i do it?!! cus i do not have the same columns in the three tables.
