IBM InfoSphere Information Server vs. Stata

Information Server is extremely useful to replace manual developments that require a lot of coding effort. It significantly increases the productivity of the initial development and the future maintenance of the processes since it has a visual development environment with self-documentation.

Although Stata is a powerful tool, it is not a very flexible one. Even if it is able to create tables and figures close to what I need, they are never exactly what I want so that I need to modify things manually afterwards. The coding itself is somewhat intuitive but the error codes are not

• IIS best for ETL ,not ELT , and many and diffrent source systems.
• It also can process big data , unstuctured data
• It is not only DWH , you can use infosphere for analys and see the bigger architecture of your OLTP systems

• I would be nice to have a new web development environment for DataStage.
• Connectivity Packs such as Pack for SAP Application are a little pricey.
• It is confusing for new developers the possibility of developing jobs using different execution engines such as Parallel or Server.

Some of the commands are quirky and appear to be duplicates of one another. The fact that Stata is so feature rich also makes the visual interface quite full.

DataStage is more robust and stable than ODI The ability to perform complex transformations or implement business rules is much more developed in DS

I think R is way more flexible but requires more built up cost. Stata is easier to learn but not flexible.
