                    Notes          10.4 Summary

                                       A cube may contain multiple viewpoints. Generally each viewpoint displays a subset of
                                       the cube that is related to a widespread subject area or that is needed by a group of users.
                                       For models that contain many subject areas, for example, Sales, Manufacturing, and Supply
                                       data, it might be helpful to Report Builder users if you create perspectives of the model.

                                       An MDX query is different from an MDX expression. An expression is a formula that
                                       calculates a single value. A query is a command that can get numerous values from a cube,
                                       generally to create a report.
                                       You can use Analysis Services as a data source for the Office Excel 2007 PivotTable and
                                       PivotChart characteristics.
                                       Analysis Services provides dimensional data that is well-suited for data exploration in
                                       PivotTables and Power View reports.
                                       From within Excel, select the Analysis Services drop down from the Data tab -> From
                                       Other Sources drop down, and then walk through the data connection wizard to identify
                                       location, cube, and credentials.

                                       Select Trusted Data Providers from the Excel Services Settings of the Shared Services
                                       Administration page. Add MSOLAP.4 to the trusted list in order for the connection to
                                       work in Excel Services.

                                   MDX SELECT: The MDX SELECT statement supports optional syntax, such as the WITH keyword,
                                   the use of MDX functions and the ability to return the values of specific cell properties as part of
                                   the query.
                                   Multidimensional Expressions (MDX) query: Multidimensional Expressions (MDX) is a query
                                   language for OLAP databases, much like SQL is a query language for relational databases. It is
                                   also a calculation language, with syntax similar to spreadsheet formulas.

                                   Multidimensional Expressions (MDX): Multidimensional Expressions is the query language
                                   that you use to work with and retrieve multidimensional data in Microsoft SQL Server 2005
                                   Analysis Services (SSAS).

                                   Perspective: A perspective is a sub-set of a model.
