The last weekend I discussed in a forum what my thesis is about. I spent some time in the answer, so why not posting it in my blog to give people a better idea what I'm working on:
When users first see Palo and Pentaho, they don't really know there is such a big difference, both claim to be a BI suite. It was the same for me, when I first started my thesis.
In my thesis I'm working with Palo OLAP Server, Palo Worksheet Server and also with Palo ETL Server compared to the Pentaho BI Suite (without Weka), otherwise it wouldn't be a good comparison. I created a test scenario, and try to provide a solution with both Palo and Pentaho.
The focus of my thesis is not to say, Palo is good, Pentaho isn't or the other way around. the result might be "if you focus on planning, you better use Palo, if you do lots of reporting, Pentaho provides more options,...
The scenario is more the practical side of an implementation: How to get data into the system (ETL), how can you design your data (Modeller, Schema Workbench, Metadata Editor,...), how can you create reports, especially parameterized and time related ones, how can you manage users and groups and their rights, do the tools provide planning posibilities. Are there special features? Since there is so much stuff to look at I can't always go into all the details of course.
