What is the difference between OLAP and OLTP and what is data warehouse?OLAP is usually called a data warehouse. However, data warehouses are only part of

propose analysis requirements on the first day and wait until the second day to obtain the calculation results. This analysis method is "offline analysis ", low efficiency.To improve data analysis efficiency, OLAP completely breaks the record-based data browsing mode, and separates data into dimensions and measures )":>DimensionIs to observe the data angle, such as the above example of "sales time", "sales

be divided into ROLAP, MOLAP, HOLAP. ROLAP represents an OLAP implementation based on relational databases (relational OLAP). The relational database is the core of the multidimensional data representation and storage. ROLAP divides the multidimensional structure of multidimensional databases into two types of tables: a fact table for storing data and dimension

multi-dimensional data as the core, that is, molap uses multi-dimensional arrays to store data. Multi-dimensional data will be stored"CubeBlock (cube) structure. In molap, "Rotate", "cut", and "slice" of "cube" are the main technologies used to generate multidimensional data reports. Holap indicates the OLAP impleme

One of the previous articles-the Data warehouse multidimensional data model already provides a brief description of the definition and structure of an overly-dimensional model, as well as the concept of the fact table and the dimension table (Dimension table). Multidimensional data model, as a new logical model, gives the new organization and storage form of data, and the advantage of the analysis is the effective operation and processing based on the

cube:Dimension is equivalent to coordinate system on axis, such as time, department;--dimension tableMetrics are data that can be reflected in a report, such as sales;--Fact sheetSo what do OLAP do with these dimensions and metrics? In fact, it's easy to use different dimensions for different business needs .For example, to show the company's sales in the first

The topic of today's blog is: parameter linkage solution. Environment: Data Warehouse + OLAP (cube) + Reporting Service. Effect: multiple parameters (1, 2 ,......) Achieve interaction. First, let's talk about the principle. A data warehouse consists of fact tables and dimensions. I understand that fact tables are actually a table composed of multiple dimensions r

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

IOS games, A newIos gamesThere are also many friends who want to know how to play the cube. xiaobian also read a lot of related information about CubeMaster on the Internet. However, the common Rubik's Cube is 3D. What would happen if I put it on a smartphone or tablet? The free 2D

Suddenly there is an idea, if you can put some of the different knowledge points on the same interface, and put in a box, so that I want to see what can be very direct display, and this box must be able to open. I use HT to realize my idea, code more than 100 lines, so little code can achieve this effect I think it is cattle.Let's take a look:The most basic of th

the data that has occurred in the transaction system to a data warehouse with a specific topic using the ETL Tool. OLAP generates cubes or reports and presents them to users through the portal, you can use the classification, tertering, description, and visualization data to support business decision-making. Note:Bi cannot produce decisions, but uses the data processed by the Bi process to support decisions. What
