Development Studio, you can create an Analysis Services project that contains the definitions of Analysis Services objects (cubes, dimensions, and so on). There are four key steps to using business Intelligence Development Studio Modeling: (1) Define an analysis Services project. (2) Configure the Analysis Services project properties. (3) to generate an analysis Services project. (4) Deploying an Analysis Services project. Scalability of the SSAS database, including: Data mining, permissi

Overview This article discusses the role of data partitioning in data warehouses. Relational data warehouses and Analysis Services cubes support data partitioning. The logical concept of partitioning is the same in the two engines of Microsoft®sql Server™: Horizontal partitioning of data through keys, such as dates. In a relational database, partitions are implemented by creating separate physical tables,

) SELECT (9) DISTINCT (one) (1) from (3) (2) on (4) WHERE (5) GROUP by (6) with {CUBE | ROLLUP} (7) Having (a) Order by In the SQL Server 2008 version, the description of the logical phase extends to all logical statements, not just join processing, such as apply, pivot, and so on. In this way, the logical steps are divided into 6 parts, and some

, generating VT6. has: has a having filter applied to VT6. Only groups that make Select: processes the select list, producing VT8. DISTINCT: removes duplicate rows from VT8, resulting in VT9. ORDER BY: generates a cursor (VC10) by sorting the rows in VT9 by the list of columns in the ORDER by clause. TOP: selects the specified number or scale of rows from the beginning of the VC10, generates the table VT11, and returns the caller. Note: Step 10, this

dimension table is critical to the fact relationship and is especially prudent.What is the difference between a fact relationship and a regular (regular) relationshipBefore we say that the fact dimension relationship is a cube calculation using the Keycolmuns column and the primary key column of the fact table in the dimension table key property, we can actually change the fact relationship to the regular (regular) dimension relationship. Because the

the aggregation of a certain hierarchy of values in the selected column. After reading the above passage, what have you realized? If not, then ...... Hey, your understanding is not enough. It's still early to go to the "Three flowers" Summit :). Next let's take a look (note that the answer will be announced soon ): -- The key is the following WITH ROLLUP -- Of course, you can also use with cube, but the results will be slightly different. After readi

In fact, this is also a forced choice, but the algorithm has its adaptation to the scene, especially in the OLAP data Warehouse, in a relatively adequate system resources environment, the algorithm has been the scene of its play.Of course, the two algorithms described above are not useless, in the business of the OLTP system library, the t
