I am a beginner in odoo (formerly openerp), and trying to create (not change a few words) new reports. For a couple of days searching I couldnt find resource for version 8 because many people are talking about 7 with some add ons for openoffice etc...

Is there any flow diagram how to create reports? or where to put files, which tags for XML or etc.. 

I am ready to buy a book and read in a night to understand the basics since I am lost at this moment with actions, views, QWEB, XML, reports, ir.actions.report.xml and many more concepts which is related with each other but very complicated if there is no source to read the relations. 

Any help will be appreciated. 

Regards,
