The Database is structured by international organisations, meetings (aka series) and meeting editions (aka events). An international organisation can be responsible for one (International Organisation A) or more than one (International Organisation B) different meeting.
Over the years a meeting consists of different meeting editions held in the past and scheduled for the future (e.g. 2014, 2015, 2016, 2017 etc.). This historical overview strongly contributes to the value of ICCA's Association Database as an information source.
An example: The International Congress and Convention Association (ICCA) is responsible for two series:
1. ICCA Congress & Exhibition incorporating the General Assembly
2. ICCA Association Meetings Programme
However, some meetings may not have an international organisation at all. In this case the past organising committee often decides where the next event will be held and who will be part of the next organising committee.
