The product dimension, time dimension, and location dimension are different coordinate axes, and the intersection of coordinate axes is a specific fact. That is to say, a fact table is an intersection of multiple dimension tables. A dimension table is a window for analyzing facts. First, we wi

Microsoft integration services is a platform that can generate high-performance data integration solutions, including extracting, transforming, and loading (ETL) packages for data warehouses. Integration Services includes graphical tools and wizard used to generate and adjust packages; tasks used to execute workflow functions (such as FTP operations), execute SQL statements, and send emails; the data sources and targets used to extract and load data. They are used to clear, aggregate, merge, and

mining. In business intelligence, data mining is the highest level. Nowadays, the value of popular big data is often reflected by data mining. If we say that the Bi process can be seen as the data yesterday, today and tomorrow, and the data yesterday, we can use reports to tell you what happened before the business, the data today, multi-dimensional analysis and other tools tell you why this happened. The data tomorrow is to use data mining algorith

The company has been involved in the development of Bi projects for a period of time, but it is only developed as needed. This afternoon, the company will train you on the knowledge of data warehouses, let's hear about the two to three hours, what latitude, theme, and almost stunned. Finally, we demonstrated the Bi-based cost analysis system, which feels complicated, it is complicated for medical project se

Conversely, the value and necessity of the existence of a report that is unrelated to any of the indicators needs to be elaborated.The sixth step: after the establishment of the index system and reporting system, how to show more can explain the problem? On the other hand, how to show the source data of the indicator and

first, what is it? SSAS is a component used for SQL Server databases for BI, which enables you to create multidimensional databases and perform data mining operations on top of them. In this article, we mainly introduce some knowledge about SSAS data analysis. Next, let's get to know each other. Business Intelligence provides solutions that capture data from a variety of data sources and can transform all kinds of data into the same format for stor

You can use this algorithm to study data that contains events that can be linked by the following path or "order". The algorithm finds the most common order by grouping or classifying the same order. Here are some examples of the order:

In power query, you can not only search online data, but also publish your own data to a line for other people to retrieve. Power query provides this built-in sharing capability through the Power BI site. In Excel, Anna opens the workbook she wants to share, which contains the 2009 Nasdaq data she previously downloaded in power query. She then decided to publish the data of her own organization to the Power BI
