Analysis Services is an online analytical data engine used in decision support and business analytics, providing the analytical data for business reports and client applications such as Excel, Reporting Services reports, and other third-party data visualization tools. A typical workflow for Analysis Services includes building an OLAP or tabular data model, deploy the model as a database to an Analysis Services instance, process the database to load it with data or metadata, and then assign permissions to allow data access. When it's ready to go, this multi-purpose semantic data model can be accessed by any client application supporting Analysis Services as a data source.
To create a model, use SQL Server Data Tools (see Tools and applications used in Analysis Services), choosing either a Tabular or Multidimensional and Data Mining project template. The project template contains folders for all of the objects needed in a model. You can use wizards to create all of the basic elements, such as data sources, data source views, dimensions, cubes, and roles.
Models are populated with data from external data systems, usually data warehouses hosted on a SQL Server or Oracle relational database engine (Tabular models support additional data source types). Models specify query objects, such as cubes, but also specify dimensions that can be used in multiple cubes, calculations and KPIs that encapsulate business logic, and interactions such as navigation and drill-through behaviors.
To use a model, deploy it to an Analysis Services instance that runs databases in a particular server mode, making the data available to authorized users over network connections:
As a Tabular instance, running Tabular models.
Tabular models can be created at compatibility level 1200 to use the newest functionality, or at the older 1103 compatibility level. There are major differences between the compatibility levels in this release. See Compatibility Level for Tabular models in Analysis Servicesfor information on how the levels compare. See What's New in Analysis Services for details about new features.
As a Multidimensional and Data Mining instance, running OLAP cubes and data mining models (this is the default).
As Power Pivot for SharePoint, running Power Pivot and Excel data models in SharePoint (Power Pivot for SharePoint is a middle-tier data engine that loads, queries, and refreshes data models hosted in SharePoint).
Same data engine; three different ways to use it. Note that server modes are set during installation and cannot be changed later. You should install a new instance if you require a different mode.

Analysis Services features vary by edition. Multidimensional and data mining models are available in standard edition, but with fewer features than higher editions. Tabular models and Power Pivot for SharePoint are premium features and are not available in a standard edition license. For more information, see Features Supported by the Editions of SQL Server 2016.
