A fact table that stores sales and sales by state, product, and month has 5 columns that are conceptually similar to the following example. Sate Product Mouth Units

This series is used to document the experience of using SSAS and Excel for data analysis in the work, in the Days of Goodness (SSAS Excel BI Tips), which is now intended to share small skills in the form of blogs, which is not enough to be explained as a separate course, but a lot of BA, Bu unfamiliar but very useful skills, dedicated to the needs of friends.This article is about the what-if hypothesis analysis of Excel, and the what-if writeback of

trends, the business anomalies to make a rapid and accurate response.Third, Insufficient data collection:Many information systems even product attribute characteristics can not be collected into the storage, resulting in the corresponding analysis of consumption tendency.The POWER-BI can help the retail chain industry achieve:1, according to channel and regional combination of best sales and best profit products, adjust the best shelf products;2, acc

partial caching Note that the size allocation of the buffer is as large as possible, 25MB in size. Reasonable use does not match the buffer, when the mismatch degree is high, the ratio of mismatched buffers is increased. No cache is not cachedNo cache mode, each match query will go to the database to check once. In this cache mode, the amount of data is small and the memory is very tight, it will be used, of course, its memory consumption is relatively minimal, but the lowest

About Silverlight for Bi This project mainly talk about the method to implement Bi using Silverlight.Now that I can find the way to render KPI and cube, It is not a control Or something, because of Silverlight, it is just tell a way to implement.

is the temporary storage area of interface data. It prepares for the next step of data processing. Generally, the data on the ODS layer is homogeneous with that on the source system. The main purpose is to simplify subsequent data processing. In terms of data granularity, the data granularity of the ODS layer is the finest. Tables on the ODS layer generally have two types: one for storing the data to be loaded and the other for storing the processed historical data. Historical data must be clea

It then captures the changed data and saves it to the specially created change table. It also enables the subscriber to control access to changed data. The subscriber needs to know what changes he is interested in. A subscriber may not be interested in all the data published by the publisher. The subscriber needs to create a subscriber view to access the changed data authorized by

For example, the lines in the following

Source: "Bi thing" data stream conversion--sortThe sort transformation allows you to sort data in a data flow by a column. This is one of the five commonly used conversions. Connect to the data source to open the editing interface and edit this task. Do not select a field that you do not want to set as a list, and all columns are selected by default. , sort by totalsugar_cnt, and output all columns.In the table at the bottom, you can set the alias of

Today we start another important part of SQL SERVER bi--reporting service, relative to integration service and analysis service,reporing Service in the domestic users should be a lot more. On the one hand, because the reporing service cost is lower, directly attached to SQL Server, on the other hand, in fact, SSRS to a large extent, or to meet the needs of our report. In SQL Server 2008, SSRS has stepped up in a number of ways, "if Microsoft invests 1

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 is low. In the Three Kingdoms data analysis,
