Answer 3

Visit http://code.google.com/p/persiphi/ if your are addicted to Delphi 2010 or upper.

Edit: Dead link as the owner likely has renounced to opensource it. Nevertheless, his master thesis work in portugese (pt-br) is still available here. A good source of inspiration for those in search of sample using latest bleeding edge features of Delphi (Annotation, Rtti...) in the realm of object persistence.

UPDATE 1:

DevArt has released EntityDAC - An ORM for Delphi with LINQ support!

It works even with D11 (Delphi 2007).

UPDATE 2:

Marshmallow ORM framework by Linas Naginionis.

It has joined join the outstanding Spring4D project as a feature branch as announced here.

Dubbed MM ORM Framework by its author, it's a promising one.

Answer 4

Another ORM for Delphi, which seems to be in active development, is hcOPF

The project is open source licensed under LGPL/MPL and hosted on SourceForge at http://sourceforge.net/projects/larryhengensopf/.

dorm, “The Delphi ORM” by Daniele Teti, was officially published at ITDevCon, there is an introduction here. It works with PODOs which have no knowledge of the ORM.

Answer 5

Another Open Source ORM for Delphi 6-XE2, which is JSON based and Client/Server.

Can use its own in memory database layer or embedded SQLite3 database engine: http://blog.synopse.info/category/Open-Source-Projects/SQLite3-Framework

Edit: A lot of improvements to this active framework, since this question was answered. It is able now to connect to any third-party database, and is changing its name: it is now called the mORMot framework.
