improve performance and ease of use, so as to help users achieve on-demand information utilization. You can use DWE to build a complete data warehouse solution, including highly scalable relational databases, data access functions, business intelligence analysis, and front-end analysis tools. DWE integrates Core Components for warehouse management, data mining, OLAP, and inline analysis and reporting. DB2

OLAP introduction (combined with personal work), olap introduction combined with personalOLTP and OLAPTraditional database systems are OLTP and can only provide raw data operations. Analysis is not supported. OLTP system: Performs online transaction and query processing. General supermarket invoicing system, functions: Registration, accounting, inventory and sales records, etc,

OLAP ClientFlexolapview User ManualOverview flexolapview component is a method for multidimensional analysis.FLASHcontrol, available through theXMLAstandard protocol connected toOLAPservers, such as: Microsoft'sSQL ServerAnalysis Server (MS ssas2005/2008) andPentahoAnalysis Services (Mondrianand so on, it can use the pivot table and a variety of charts to display multidimensional Analysis data for real-time business analysis. This article describes

user's requirements, and then develop applications and create databases for the user's purpose. What is an OLAP report tool? In the report market, there is a strange phenomenon: the technical staff of the IT department is the department staff most unfamiliar with the use of report tools in all departments of the enterprise, but the report data comes from the IT department. The IT department often uses th

(Factor Measure). The user uses OLAP tools to perform multidimensional analysis of data from multiple angles. OLAP is generally considered to include three basic analytical operations: roll Up (Rollup), Drill Down (drilldown), Slice cut (Slicingand dicing), and the original data is aggregated and organized into a view of one or more dimensions.ROLAP and MOLAPTra

environments. Its core technology is the concept of "dimension. "Dimension" is a high-level classification from the perspective of observing the objective world. Dimensions generally contain hierarchical relationships, which are sometimes quite complex. By defining multiple important attributes of an object into multiple dimensions, you can compare data in different dimensions. Therefore, OLAP is also a collection of multidimensional data analysis

complex. By defining several important attributes of an entity as multiple dimensions (dimension), the user can compare the data on different dimensions. Therefore, OLAP can also be said to be a collection of multidimensional data analysis tools. Basic Multidimensional Analysis operations for OLAP include drillthrough (roll up and drill down), slices (slice) an

Therefore, OLAP is also a collection of multidimensional data analysis tools. OLAP basic multidimensional analysis operations include drilling (roll up and drill down), slice, dice, rot

" structure. The attribute values for the dimension are mapped to the subscript or subscript range of the multidimensional array, and the summary data is stored as the value of the multidimensional array in the cell of the array. Because MOLAP uses a new storage structure, which is realized from the physical layer, it is also called physical OLAP (PHYSICALOLAP), while ROLAP is implemented mainly through some software

Outstanding Features Allows for rapid, direct analysis of comprehensive financial, mathematical and statistical functions and computational functions Combine the flexibility of relational databases with the high performance of multidimensional storage to provide a web-enabled platform, easy access to enterprise-wide information enabling rapid application development and data modeling enables multiple users to simultaneously read and write to "what if" applications to support third-party analys

. So why should we add such a "data warehouse" between operational databases and bi?First, the operational database is busy day and night. It aims to respond quickly to the business and has no energy to meet the data requirements of Bi. In addition, the data requirements of Bi are usually summarized, A select sum (XX) group by XX can make the operation-type database consume a lot of resources, and the business processing can't keep up with it. The trouble is huge. For example,

system. This involves operations such as data cleanup and aggregation. Loads data into a data warehouse or data mart. The process of fetching data from OLTP and legacy data sources and converting it to a warehouse server is known as the ETL process, which is usually run periodically, such as once a week or once a month. Once data is loaded into the data warehouse, an important function of OLAP systems is to provide decision makers with the conveni

combination of these dimension members uniquely determines the value of a variable. In this case, the data unit can be expressed as: (Dimension 1 dimension member, dimension 2-dimension members ,..., Dimension n-dimensional Member, variable value ).For example, the "toothpaste", "January 2004", "Shanghai", and "wholesale" members of products, regions, time and sales channels are used ", the only value that determines the variable "sales" (assuming 100000) can be expressed as: (toothpaste, Janua
