An application’s value is not measured in SQL object count. Centralizing logic can help consolidate an application into smaller, more manageable chunks.
For example, several “Customer” based pages select records from the Customer table. The table has an “Active” bit, and can be modified so that only “Active” customers show up on these pages. Many of these existing “webCustomer*Hor” views may already have complex WHERE clauses. Appending “[Active] = 1” to every WHERE clause adds complexity to the WHERE clause, and makes it less readable and cumbersome to maintain. Instead, create a supplemental active view such as “webCustomer_ActiveSel” and replace all of the “FROM [Customer]” sections with FROM [webCustomer_ActiveSel]. This way, if the definition of “Active” changes, it’s an easy change in one view, instead of many.
Procedures are another common place to consolidate logic. SQL stored procedures can be considered object oriented code in the eyes of the developer. Consolidate any logic that is more complex than a single SQL statement into a procedure. This greatly reduces the chance of bugs occurring, and centralizes the logic so that a developer doesn’t have to remember where everything is.
For example, place logic such as “When I see an update to set a field to 1, I also now need to go set this other field to 2” into a stored procedure. Updates to this logic can then be added in a single place.
