Wonder if that's why we continue to use PL/SQL to interact with Oracle. It's just fast and easy...

		The vast majority of software that people write inside a business talks to a database. Yet object orientated 
		programming does not gel well with databases. The code that looks clean and simple in a modern object 
		orientated program looks positively terrible when you look at the traffic that code causes at the database.

		It's called the <A href="http://en.wikipedia.org/wiki/Object-Relational_impedance_mismatch">object-relational impedence mismatch</A>. The often aired solution is to use some sort of persistence framework to map your classes 
		to a collection of database tables. There are a variety of packages that do this: NHibenate, Gentle.Net, 
		JPersist etc.

		Solving the impedance mismatch problem is the computer science equivalent of the perpetual motion machine. 
		You can't get it to work because it's impossible; they are simply incompatible ways of working.
