OpenDBX -> it is a database abstraction written in C. It was developed outside the community, though we contribute if necessary. There is also a driver in Pharo providing bindings against this opendbx library.

Garage -> a database abstraction in Pharo. It provides a common interface to talk with several drivers (e.g., opendbx, native postgres, native mysql...)

Glorp -> an object relational mapping framework that connects to a database (therefore it needs some database driver) and converts relational data into objects.

DBXTalk -> the umbrella project of all the above (and their connections)
