Question: Why Bi, statistics and analysis of massive data through BI solutions, compared with pure tsql statistics, can improve query and analysis performance, in addition, multidimensional analysis can help customers better understand data. Recently, I have been asked a few similar questions, so I have summarized some of them and gradually gained an unformed accumulation, which is roughly recorded as follo

few similar questions, so I have summarized some of them and gradually gained an unformed accumulation, which is roughly recorded as follows. Microsoft may be subject to some restrictions, so the support of many products in China is not very powerful, and there are fewer people engaged in related development. Based on my experience over the years, this article provides some reference projects for your evaluation. According to different situations, th

Two days ago, ziliang (DAI ziliang) sent me a text message, today, the Microsoft Bi pioneer conference and two technical lectures on business intelligence and data mining will be held in the yongyu le conference hall of Kingsoft on the 20 th Floor of baiyan building, my former colleagues, Jin Ligang and Wang rutao, are both senior lecturers and practitioners in the field of business intelligence in China, I

Microsoft (Microsoft) In the simplest terms, business intelligence is an effort to acquire and analyze enterprise data to better understand the market and customers, improve business processes, and more effectively participate in competition. Provide the right information to the right decision makers at the right time. business intelligence enables enterprises to make better decisions at a better time than

To find out how complex it is, look at the SQL Server Books Online description of the algorithm: "This algorithm establishes a classification and regression mining model by establishing a multi-layered perceptual neuron net

Introduction to the outsetFrom Tian Shan College A student's question, how to import data from an ACCESS datasheet in SSIS.Import ACCESS database data in SSISAccess is actually a lightweight desktop database that is stored directly in the form of files. There is not much use of access as a BI data source in the country, but it is more used abroad, especially in the United States, because their IT base starts early. In my first American health insuranc

Original: "Bi Thing" Microsoft cluster analysis algorithm--three-person identity divisionWhat is cluster analysis?Cluster analysis is an exploratory method of data analysis. In general, we use clustering to group and categorize seemingly unordered objects to better understand the object of study. Clustering results require that the similarity of objects in group is higher, and the similarity between groups

the relationship between two contiguous columns. For example, you can use linear regression to calculate trend lines based on production or sales data. You can also use linear regression as a basis for developing more complex data mining models to evaluate the relationships between columns of data.Although there are many ways to calculate linear regression, and these methods do not require data mining tools, the advantage of using the Microsoft linea
