Q:  

I work in a big data warehouse and we are using ETI*EXTRACT as ETL tool. This is a code generator, but we are thinking about trying an ETL tool from Informatica. What is the run of the market? Code generators or database engines? What is the most extended tool in the world? What is the most extended in telecommunications industry? I know EXTRACT very well, but I'd like to get an independent opinion about Informatica. We manage a large amount of data with huge text files. Would it be a good idea to change to Informatica?
