While we're on the subject, will one of you framework experts clear something up for me?
I work on an Intranet application that leverages data from a few huge databases, some of the tables contain millions of records. The queries we need to write to gather data can be very complex, often times in the hundreds of lines. Something I've often heard in the framework discussions is that you guys use these DAO thingies to simplify access to your data. I have always doubted that a DAO would be useful for my scenario, because our data queries are often very complex. Here are the two big reasons I've heard people cite for using a DAO: 1. Abstraction of your database 2. Caches the data Sure, we /could/ use a DAO, but it would be very specific to the one report it is used for. What's the point of using an object if you only need it one page? Also, I really don't want the millions of records that would be filtered sitting in memory on my server. The whole reason databases were created in the first place was so that you don't /have/ to carry data around in your applications, you just grab the pieces you need, when you need them. Caching makes sense if you have a user table with a couple hundred records, but when you are querying a financial ledger that contains millions of rows, I'm not sure I'd want to pre-cache the data. I realize I may be butchering things here, as I've never used a framework. So please don't take this as an attack, but rather as an attempt to understand the benefits of frameworks, and how they could help me.
