I first started looking at ORM tools in 2002 when we announced a preview of ObjectSpaces at the PDC. I thought it would be fun to find a list from those early days and see how many of the tools survived the test of time.
From I found a pretty decent list (although I remember a few more were around at the time!). I have no doubt got some of this wrong as these things “move around” – just drop me a line if you spot any of these are still alive.
Lets see how they faired:
- .NET Persistence – Domain for sale
- – No such site
- – No such page
- – LIVE. V4.0 is the most recent.
- Data Tier Modeler for.NET – Appears to no longer be a product
- DotNorm – No such site
- Eldorado.NET – Died 2004
- – Still part of Borland?
- – Now only a consultancy
- – LIVE. DevExpress XPO
- Genome – LIVE
- JC Persistent Framework – Died 2005
- LLBLGen Pro - LIVE
- ModelWorks – No such site
- Nhibernate - LIVE
-
- LIVE
- Norm – LIVE (I think) as
- – Domain for sale
- ObjectBroker – Died 2003
- ObjectPersistor.NET – No such site
- – Never shipped
- ObjectSpark – might be part of EdgeNode
- Objectz.NET – broken site
-
- Died
- OPF.Net (Object Persistent Framework) – LIVE at
- ORM.NET – Died 2007
- Pragmatier Data Tier Builder – No site
- – No site
- Sisyphus Persistence Framework – Died 2002
- TierDeveloper – Mothballed but still available for download.
- Versant Open Access – LIVE. Became Telerik OpenAccess http://www.telerik.com/products/orm.aspx
Final score card:
Out of 31 ORMs, 9(ish!) ORMs lasted the 5 years since the list was originally compiled.
