Every month (except in July, August and September) the EDSC provides workshops that explain the use of our financial databases. These workshops are organized by topic. This makes it possible to compare ways to collect the same data from different databases in a single workshop. We make an exception for Bloomberg: we notice that for a lot of users this is the most difficult database to use. Collecting data from this system differs greatly depending on your topic.  That's why we will still offer a workshop specifically aimed at this database.

The EDSC offers the following workshops:

  • Introduction workshop
  • Mergers & acquisitions, IPO
  • Stocks, indices & index constituents
  • Annual report data
  • CEO & Board
  • Identifiers & merging your data (Excel/Stata)
  • Bloomberg
