Jukka, Thank you for your suggestion. It looks like there is some excitement among other programmers about the ability to use SQLLite, H2, or a similar database to support writable large datasets in OpenJUMP. I agree with the comment in your post, PostgreSQL can be a pretty big elephant for a lot of users.
I have done some work on feature caching for large datasets using binary files accessed directly from Java. However, this work isn't currrently complete. It would be another option. I personally prefer this solution, as it doesn't require the complexity or overhead of JDBC and/or network communications with a separate software package. This would be a good project for a Google Summer-of-Code student. :] SS On Fri, Jan 9, 2009 at 5:09 AM, Rahkonen Jukka <jukka.rahko...@mmmtike.fi> wrote: > Hi, > > Sooner or later all data do not fit in the memory and OpenJUMP user has > troubles.
