One Star

The way from OLTP to OLAP

Hi@all,

 

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 :-)

 

Thank you for ya help.

Re: The way from OLTP to OLAP

Hello,

Do you want to transfer data from your OLTP db to OLAP db? Talend supports ETL from input source to output source. 

Best regards

Sabrina
