Data WarehouseThe middle of the 80 century, "the father of the Data Warehouse Mr. William H.inmon defined the concept of data warehousing in his book" Building Data Warehouses, "and then gave a more precise definition: The Data Warehouse is a topic-oriented, integrated, time-related, and relevant in business management and decision making, A collection of data that cannot be modified. Unlike other database applications, a data warehouse is more like a process for the integration, processing, and

server|sqlserver| data The construction and analysis of SQL Server Data Warehouse (i) Basic concepts: 1. Cubes: Cubes are the primary object in online analytical processing (OLAP) and are a technology that allows fast access to data in a data warehouse. A cube is a collection of data, typically constructed from a subset of the Data Warehouse, and organized and summarized into a multidimensional structure defined by a set of dimension

In OLAP technical documents, there are two main types that are often mentioned: multidimen1_olap (molap) and Relational OLAP (ROLAP). In order to combine the advantages, based on the two, a new type of Hybrid OLAP (holap) is proposed, that is, Hybrid OLAP technology. From a technical point of view, ROLAP (microstrategy

I. Measures, indicators, indicatorsMetrics and dimensions constitute the main concepts of OLAP , and are measures for numerical, continuous fields stored in a fact table or a multidimensional cube. This conforms to the above meaning, there is a standard, a measure field is definitely a unified unit, for example, the number of yuan, households. If a measure field, where the measure may be the euro and possibly the dollar, then this metric cannot be agg

intelligence can assist business decision-making, which can be either operational or tactical or strategic. To turn data into knowledge, you need to leverage technologies such as data warehousing, online analytical processing (OLAP) tools, and data mining. Therefore, from the technical level, business intelligence is not a new technology, it is only data warehousing, OLAP and data mining technology, such a
