Hi, For how long ObjectDB will exist and will be actively maintained? Will it still be there in 10 years ? In 20 years ? Thanks. randomguy Anton Yes, ObjectDB is an active project and will probably be here in the next 10, 20 and 50 years . Your question is fair because the ODBMS market in general

Today, after years of hard work, ObjectDB 2.0 was released and is available for download. In addition, in order to make ObjectDB more affordable, the pricing model was changed: The prices of the Server, Site and OEM licenses were sharply reduced. ObjectDB 2.0 licenses will now include free updates

Hi, We're having our system with ObjectDB 2.4.5 in production since this year April and it works just fine. However, now we've discovered that suddenly partial Objects in some DBs in production do have a UUID String as their id instead of Long which is of course causing a lot of troubles. Note
