tableau olap

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

Powerful companies such as IBM,Oracle, Sybase, CA, NCR, Informix, Microsoft, and SAS have launched their own data warehousing solutions (through acquisitions or research and development). Professional software companies such as Bo and Brio also have a place in the front-end online analytical processing tools market. The following is an analysis and comparison of the performance and characteristics of these data warehousing solutions. IBM offers a suite of business intelligence (BI) solutions ba

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

server| Concept | data 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 dimensions and measures.2. Dimensions: is a structural feature of a cube. They are organized hierarchies (
