Обсуждение: Free OLAP software for Postgres databas
Hi, I'm looking for free software that provide OLAP functionality (or more general BI) for data that are stored in Postgres database. I've found Pentaho and Jasper but both sollution are configured for MySQL. Can you recomend something that works with postgres? Regards

I'm pretty sure jasper as well can work with pgsql.

We used the free version, and the docs that came with it covered jdbc connection. It's been a couple of years since I was part of that project, so the memories aren't real clear. Just remember hooking it up to pgsql was the easy part.

We also both the free and enterprise versions, and both work with PostgreSQL. Note that there are two different things you might be talking about, here: 1) PostgreSQL contains your data warehouse, or pieces thereof. 2) PostgreSQL contains the Pentaho repository The first is easy; simply configure data sources pointed at the PostgreSQL database. Note that the JDBC drivers that ship with Pentaho are, in my experience, of inconsistent version, and you might want to update them to the latest available for your PostgreSQL and Java versions. The second is more difficult, but also very possible. There are PostgreSQL scripts in Pentaho's biserver/data/postgresql directory. These create the necessary databases. Though they're poorly written, IMO, they'll give you a good idea what you really need to create. The hardest bit is editing all the configuration files for the various bits of the Java stack (spring, hibernate, acegi, pentaho...). It's best to find instructions for using MySQL as the repository, and substitute "PostgreSQL" for "MySQL".

If it is not the versions that they come with the chances are that things will not work. The JDBC driver might be upgradeable, I believe we downloaded that by ourselves. Also we had a much better experience with Jasper (free version) then Pentaho (free version).

We've not had problems upgrading the JDBC drivers (or indeed installing them, as IIRC, some components just haven't had a PostgreSQL driver in the default installation). Your Mileage May Vary. We haven't touched any other libraries that ship with Pentaho, which I tend to think is a wise decision on our part :) > Also we had a much better experience with Jasper (free version) then > Pentaho (free version). When we tried to decide between the two, we took both out for brief test drives. They seemed almost functionally equivalent, and there were no major advantages or deficiencies we found to indicate one over the other. But that's a decision made with regard only to those features we cared about. - Josh / eggyknap
