Hi,
just had a quick browse for what's going on in .net persistence for C#
and would like to see whether there is more?

what I saw was basically
* Pragmatier for VB.NET.net and C#
* FastObjects for C#
* ObjectSpaces
* a db4o port announced ...

Are there any more serious persistence products than that in the .NET
arena or is that it?

Thanks, Wolfgang

PS: I'm not counting JDBC similar stuff like ADO.NET but I'm interested
in
stuff that looks more similar to transparent persistence suites from the
Java side
like JDO, Hibernate and the like
PS2: Please no discussion that JDO is not transparent :-) ...

Take a look at the Tools List at http://groups.msn.com/DotNetPersistence

There are generators on the list as well as frameworks, but you should be
able to get an idea of what's out there.

Hi Wolfgang,

db4o for .NET has been released in the meanwhile.

It comes with exactly the same functionality as our Java version:

- No enhancer, no byte-code-engineering, simply store objects as
they are, with one line of code:
ObjectContainer#set(yourOwnComplexObjectHere);

- Support for all types available on the .NET platform, including
structs and Collections.

- Classes are analysed with reflection during runtime. Changes
to the class scheme are detected automatically and you can continue
to work with the same database file, without a reorganisation run.

- Query-By-Example and S.O.D.A. object query interface.

- Client/Server functionality, ACID transactions.


db4o for .NET comes as a 225 kB DLL and can be used from all
..NET languages.

It can also be run on the CompactFramework (PocketPC, Windows CE,
Windows Mobile 2003).

A trial version is available for download on our website:
http://www.db4o.com


Kind regards,
Carl

For those of us, who read french there's also another interesting
one, which is http://dotnetguru.org/ who have sections on persistence
and also ObjectSpaces
Cheers, Wolfgang

Hello Wolfgang,

Matisse ( http://www.matisse.com ) has been supporting C# and VB.NET
for more than a year and a half.

- Provide both object based interface, and SQL interface with
ADO.NET

- ADO.NET is extended so that SQL queries can directly return
objects without o/r mapping

- Support server-side method execution

- ACID transactions, client/server, object caching both in client
and server, and more

That's an interesting .sig line. How do you justify it? How is Matisse's
logical data model is as simple and as powerful as the relational model?
