The ISOE 2 Database is composed of ISOE 2 Static and ISOE 2 Dynamic questionnaires.
The ISOE 2 questionnaire data were collected for the first time in 2003.  

However, due to the small number of questionnaires available in the database, the ISOE Management Board decided in 2011 to stop data collection and to keep existing questionnaires as pdf files on the RP library of ISOE Network.
