I have just created a db with 8 tables that each have over 1000000 rows(data collected for every second over the summer :S) I am planning on creating views so that a week can be selected at a time. I was wondering does it go against any unwritten db rules to create several databases that just contain views (one for each week of the summer) or is there a better way of doing this? The reason I would like to create these views is that it would make things easier for the customer of the data.

    Sounds like you want to create DATABASES containing views. Sounds like they’d be reading, cross-database, into the source database’s tables. That likely would lead to a performance problem down the road. In other words, non-optimal.

    Suggest that the views really should belong in the source database. If your strategy is to have a view represent a week, that’s perfectly reasonable.

    CREATE VIEW InvoicesWeek30 AS
    SELECT foo, bar, CustomerID
    FROM  Invoices
    WHERE InvoiceDate BETWEEN Date1 AND Date2

 ...
 SELECT * FROM InvoicesWeek30 WHERE CustomerID = 99
