The three types of information views are:
1. Attribute view
Attribute view uses attributes, or the non-measurable, non-quantifiable data to design views and models according to the business logic.
Thus, the data used in attribute view is referred to as ‘Master data’ as it is used as reference information in other views (analytic and calculation). The tables in attribute view do not contain any facts or measure.
2. Analytic view
In an analytic view, we can create star schemas, having a central transaction or fact table and multiple dimension tables linked to it via primary keys. The measures are contained only in the central transaction table which can be grouped or joined with multiple dimension tables.
3. Calculation view
Calculation view is an advanced model which uses both attribute and analytic view elements in it to make a complex data model following complex business logic.
It gives us the freedom to combine and create from a range of options like tables, column views, analytic views, attribute view, etc. It enables us to do multidimensional reporting using measures and dimensions from different sources.
