I made my first steps with talend this week and like it very well! The last years I did all my reporting stuff by using OLTP databases. I just updated an "analyzing-database" every night and then I got my business answers with sql code. Now I wanna level up by using OLAP with its star schema. I know how it's work, but I really don't know WHEN I have to made the changes from classical relational structure to multidimensional structure. I've loaded different kind of sources and mixed it on a tMap Element. Technically everything works fine, but stupidly mixing/joining tables seems not to be the solution 🙂
