The goal of the pattern is to keep the in-memory representation and the persistent data store independent of each other and the data mapper itself.
Since SQL is declarative, there are typically many alternative ways to execute a given query, with widely varying performance.

Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between a relational database and the memory (usually the heap) of an object-oriented programming language. This creates, in effect, a virtual object database that can be used from within the programming language.
