Tabular Model Databases (SSAS Tabular)
A tabular model database is an Analysis Services database that you create in SQL Server Data Tools (SSDT) using the Analysis Services Tabular model project template, where tables and relationships are the primary structures for representing data.
Tabular model databases are easier to build than multidimensional databases, particularly if you have a relational database background. Otherwise, administrative tasks are similar if not identical to database administration of a multidimensional database. The same tools and approaches apply.
