Thorsten,

Thanks for the feedback. My comments inline.

No, I think it's way more easy to "create a postgresql view" rather than 1/
extract 2/ load in data warehouse 3/ design olap cube 4/ design reports.

Not sure I understand what you mean here. But we have a task to extract to
Excel.

But we will have a tool extract to excel (or you can put the code in the
postgresql view).

Not sure about that.

The main CON I see with our approach is that it does not allow to report on
others sources than OpenERP (others BI tools are designed to consolidate
data from multiple sources/software).

Spreadsheet integration.
And, yes, having an ethercalc integration would be even more powerful. (but
not yet in our plans)



In my opinion, BI tools are bloated and complex because in the past, 10
years ago, it was tricky to compute on millions of records. So, they needed
to design cube structure to organize data based on the way the user will
report, separate data warehouses to not impact production servers, ... But
now, since the hardware computation power has been multiplied by 200 in 10
years, since servers have multiple cores, and since PostgreSQL performance
evolved a lot, we don't need such a complex architecture to compute on
hundreds of millions of records.

This is why I think we have an opportunity to do something different than
the traditional, bloated, BI tools. Our solution is only pre-v1, so it does
not have tons of features. But, since it has only 1000 lines of code, it's
super fast to add new features on top of it. So, even if a feature is
missing, it's not even an issue as the cost of developping the feature will
most probably be lower than the cost of trying to integrate a BI tool.


But the most important is that integration is a so big value that it
counter-balance every missing feature you may have. Would you consider
deploying OpenERP account, sales, mrp but use another software for stock?
For sure no, it looks like a very bad idea!

For me, it's the same for BI; using OpenERP for accounts, sales, stock but
another software for reports is a very bad idea. (even more important than
stock as reporting is linked to ALL applications of OpenERP whereas stock
is mostly linked to sales and accounting only) (*)
