	Analytic Vision
		Multidimensional OLAP databases are very good at handling a large variety of aggregated hierarchies.
		While this sounds similar to a relational star schema database, the difference is that the multidimensional database pre-aggregates many levels of the combinations of hierarchies for the many intersections across all of the dimensions.
		Multidimensional data is organized hierarchically, allowing users to "drill down" for more detailed information, "drill up" to see a broader, more summarized view, and "slice and dice" to dynamically change the combinations of dimensions that are being viewed.

	Multi-Dimensional Meditation
		As multidimensional beings, we are multidimensional expressions of Being.
		As all of them are expressions of One Presence, the unity of our life comes from all of them being permeable and open to Presence, and to each other.
		The heart is a good holistic symbol, for it variously means the physical organ so central to our living, the emotional center that we feel in the chest, the sense of the innermost meaning or "heart" of the matter, and the intuitive or spiritual essence.

	Multidimensional Expressions (MDX) Reference
		Multidimensional Expressions (MDX) is the query language that you use to work with and retrieve multidimensional data in Microsoft SQL Server 2005 Analysis Services (SSAS).
		MDX utilizes expressions composed of identifiers, values, statements, functions, and operators that Analysis Services can evaluate to retrieve an object (for example a set or a member), or a scalar value (for example, a string or a number).
		In order to create MDX expressions used to design or secure cubes, or to create MDX queries to return and format multidimensional data, you need to understand basic concepts in MDX and dimensional modeling, MDX syntax elements, MDX operators, MDX statements, and MDX functions.

	Using Sets in MDX Queries
		An expression can be used within various applications, among them Excel PivotTable Reports or an Office PivotTable List, to retrieve values from an OLAP data source.
		We often juxtapose numerous expressions, and the values they retrieve, to obtain a multidimensional value for analysis.
		Recall from previous lessons that a cube is a conceptually multidimensional structure; the intersect points / intersections of the dimensions are where data reside, in single or multiple elements called measures.

	An introduction to the benefits of online analytical processing (OLAP)
		It uses a multidimensional database which directly stores the information contained in the various cubes.
		The primary disadvantage to this solution is that it does not, generally speaking, perform as well as a MOLAP database.
		This is the balance between the data efficiency of the ROLAP model and the performance of the MOLAP model.
