Datamodels and questionnaires

Datamodel and questions The Blaise language is suitable for creating a computer assisted survey. The questions can be described in a data model. The data model contains information comparable to a code book, describing a fixed structure of the survey data. The data model can also contain rules, where you for example can specify the question order and conditional routes and checks. In many cases a Blaise datamodel describes a Blaise questionnaire, but this is not necessarily the case. A datamodel can also describe the data structure of a coding table, or a readily available database.
