Good Article on Database Abstraction

Found this article through planet MySQL. In it he goes over 4 different “types” of abstraction layers that typically are collectively called a “database abstraction layer” - though they are very different from one another. I found it an interesting read.

His 4 types:

1. A software library to connect to a database server and issue queries, fetch results etc.
2. A software library to present a common API to different database servers.
3. A software library to automatically generate portable SQL queries.
4. A software library to map Object-Oriented Programming to a relational database (Object-Relational Mapping, or ORM)
