Hi all,



I am looking for an open source in-memory database for data mining
purpose. I have tried to look into /usr/portage/dev-db/ and have not
found any in-memory package. Any suggestion?

*

Thanks in advance

Hung

What kind of database are you looking for? There is several ways of in-memory
db: Berkley DB, native languages hash tables and etc

Hi Alexander,*

Thanks a lot for your quick reply. I just start my project then I might
have to try some in-memory dbs and see which one is suitable for my
application.



Thanks

Hung

You might use dev-db/sqlite and put its files on a tmpfs directory.

Or, even, just use SQLite's support for in-memory databases... a
little about that's here:

SQLITE supports holding a database in memory. I never did it in python,
but in PHP if you put "memory" in the connect string rather than a
filename, the database will reside solely in RAM.


As this is a sqlite feature rather than a PHP feature, it should work
under python as well (but I've never done it, so I don't know the syntax).

mysql has a `memory' table engine.
