Datastream allows access to several databases of Thomson. The following data is available:
- Stock prices
- Accounting data
- Bond prices
- Option prices
- Interest rates
- Exchange rates
- Macroeconomic data
The access to Datastream is restricted to four terminals in the basement of the "Bibliothek für Betriebswirtschaft". The data can be loaded with the program "Datastream Advance" or with a plug-in for Microsoft Excel.
Please note that certain data cannot be loaded, because there is not a subscription for all databases of Thomson (Worldscope, IBES etc.). IBES data are available via the Wharton Interface.
Some important points for the use of equity data can be found in Ince und Porter (2004).
Unfortunately, it is not possible for us to offer an introduction in the use of Datastream. However a tutorial can be found in the menu of the program under Help/Online Manuals/Getting Started.
