Breaks

In 2006, a new data source was added and DBC ('diagnosis treatment combination') was introduced in hospitals. In 2008, GGZ-data (mental health care) was introduced and in 2012, DOT (trajectory for new declaration system) was introduced.

Strengths: The dataset is a multidimensional database.
