I need help with develop the database structure for the categorize system called eCl@ss.

I have the all the raw data in XML and CSV format.

When the project is ready it should look like this: [url removed, login to view]

One extra feature: should be able to add custom entries stored in a separate tables, if I feel one item is missing (see global custom list).

Raw files in CSV format: [url removed, login to view]

If you recommend to build this in for example MongoDB please give me arguments why we should do this.

In a later stage we will link the each unique 8 digits eCl@ss code with other standards such as [url removed, login to view] and I have also these raw files.

The developer I choose I would continue to work with to further do the above steps and much more.
