DAL / Persistence Layer Comparisons
I was curious yesterday about which databases were supported by which ColdFusion Data Access Layers (DALs). I went to check on that and before I knew it, I had compiled quite a few comparisons on each.
Perhaps I should back up at this point and explain what I mean by a DAL. I DAL is any application that manages access to data (usually a database). These are often referred to as an ORM. An ORM, however, is one type of DAL (one that maps objects to a database). An ORM is a DAL, but a DAL need not be an ORM.
