Cube Cell

Cell positions in the cube are defined by the intersection of dimension members, and the measure values are aggregated to provide the values in the cells.

Interacting With Analysis ServicesThere are three ways to interact with Analysis Services: SQL Server Management Studio, Business Intelligence (BI) Development Studio in project mode, and BI Development Studio in directly connected mode.

Data source viewsThe data source view is an abstraction layer that is used to extend the objects (relational tables and views) that are exposed by the data source to a collection of objects from which Analysis Services objects are created.

Designing Cube A cube is a multidimensional structure that contains dimensions and measures. Dimensions define the structure of the cube, while measures provide the numerical values of interest to the end user. Cell positions in the cube are defined by the intersection of dimension members, and the measure values are aggregated to provide the values in the cells.

Cube

Designing DimensionsDimensions are a structural attribute of cubes. They are organized hierarchies of categories and (levels) that describe data in the fact table. These categories and levels describe similar sets of members upon which the user wants to base an analysis.Dimensions can also be based on OLAP data mining models. They can be used to store the results of a mining model analysis and can be browsed within the context of a virtual cube.

HierarchiesSQL Server Analysis Services lets you create user-defined hierarchies. A hierarchy is a collection of levels based on attributes. For example, a time hierarchy might contain the Year, Quarter, Month, Week, and Day levels. In some hierarchies, each member attribute uniquely implies the member attribute above it.

HierarchiesA hierarchy is a collection of logically structured levels based on attributes. In some hierarchies, each member attribute uniquely implies the member attribute above it.

Deploying and Processing CubeAfter making structural changes to a cube, you must process the cube before attempting to browse its data. When you process a cube, the aggregations designed for the cube are calculated and the cube is loaded with the calculated aggregations and data. Processing a cube involves reading the dimension tables to populate the levels with members from the actual data, reading the fact table, calculating specified aggregations, and storing the results in the cube. After a cube is processed, users can query it.

Cube objects

CalculationsA calculation is a Multidimensional Expressions (MDX) expression or script that is used to define a calculated member, a named set, or a scoped assignment in a cube Key Performance Indicators

ActionsAction is a client command that is defined and stored on the server

PerspectivesA perspective is a read-only view of the cube

Translations, Custom assemblies, user-defined functions, and MDX scripts

Besides the dimension usage, measure groups, and partitions, the cube has other objects in it.
