Smalltalk binding to db4o?

Hi Stewart.
What about the Java Native Interface from Smalltalk?

Hi Steward

You could give it a try using the DotNETConnect utility shipped since
VisualWorks 7.4. It allows you to integrate .NET functionality into
VisualWorks.

And it was developed by some of my collegues ...

there is no need for end users to install the database separately. On
the other hand, DB4O does not seem have any built-in security or
garbage collection.

If you are looking for a similar database implemented in Smalltalk,
you might want to look at Magma (http://wiki.squeak.org/squeak/2665).
Magma is free, implemented in Smalltalk, but is only available for
Squeak. There is no VisualWorks port, but from what I have heard it
should not be that hard to move. I really think VisualWorks also needs
a database like Magma / DB4O!

There is of course GemStone/S, but it is too expensive for many projects.

Thanks Roland,

Unfortunately .NET would kill cross platform portability I belive, so
it's a no go.

Cheers,

Stewart

Yes, it looks good. Got some heavy weights backing it too...

Thanks for the pointer to Magma - it looks promising.

I couldn't agree with you more. I've implemented a rudimentary, coarse
grained pessimistic locking one using BOSS, but something like
db4o/Magma would make a great add on. For a shrink wrapped product, the
database management has to be seamless.

Mine included!

Cheers,

besides those you can also look at Tideland SOS: http://wiki.tideland.biz/wiki/TidelandSmalltalkObjectStore
