Martin McClure is giving a general overview of GemStone/S - the fact that we have an audience that needs a general overview of GemStone is a good sign all by itself (lots of new people).

If you're interested in getting started with GemStone, you can head over to their site and grab their non-commercial download.

Here's an interesting observation: How big can GS go?

• Not limited by memory (it's a database)
• Billions of Objects
• Hundreds of Gigabytes
• Collection sizes in the millions
• indexes
• queries

"GemStone isn't an object database, it's a Smalltalk implementation that includes an object database". Another interesting thing - you can work with different versions of objects (not everything needs to be migrated up at once).

In general, this is a great introduction to GemStone/S - the video will be worth watching.
