Refactoring SQL Applications

My past as a DBA probably makes me a bit biased, but the reaction I’ve seen the most when a database application isn’t performing as well as would be liked seems to focus on the database side of things. The search for a solution usually seems to center around tuning db parameters, the building (or removal) of indexes and if the budget allows, throwing hardware at the problem. In their new work, Refactoring SQL Applications, Faroult and L’Hermite bring a much wider range of options to the table. There is a lot in this little book for the developer charged with fixing an existing application and I think a lot of good information that could save one from making a number of head-ache inducing mistakes on a new application.
