A '''Domain''' in MINT is a view on data residing in a data source, e.g. in an IMSMA staging area. It presents the data in a certain context and allows end-users to access that data in a comprehensive way. A domain can be compared to a ''view'' on the database - it in fact implements a view functionality within MINT. This means that instead of having a view object directly on the database, a domain is a metadata layer residing inside MINT.
A domain has to be '''designed''' by a MINT administrator. It is based on database tables (and potentially views), derived tables, joins between all the specified tables and derived tables, calculated fields, display names, and certain properties that can be defined, such as security and localisation.
In short, a domain '''presents''' selected data field to an audience, i.e. to end-users running reports and designing dashboards.
