ssas tutorial

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 al

Problem: In some scenarios, data centers are divided into different server farms: Database farms and Applications Problem: In some scenarios, data centers are divided into different server farms: Database farms and Applications Problem: In some scenarios, data centers are divided into different server farms: Database farms and application farms. There is strict firewall control between server farms, where the database farm can only be built from the application farm firewall, that is, no clie

After the SSAS multidimensional model is built, in addition to the Excel client directly linked to the SSAS source drag pivot Analysis use, you can also tell the result set to be displayed through the MDX statement query, embedded in the program, run the program to run out the complete report. ：MDX for OLAP datasets is like Transact-SQL for Microsoft SQL Server relational databases. In SQL MdxQuery Query wi

Named sets in SSAs are frequently used in projects. Common functions such as topcount, filter, and exists can be set as static namespaces, some do not work. For example, if topcount is set to static set, it doesn't make much sense. It is related to the performance problem of accessing SSAs in Excel today, in the support phase, it took nearly 20 seconds for a project to access

When we create dimensions in SSAs, it is sometimes possible that one dimension needs to use multiple table fields as dimension attributes, so there is bound to be an association between the multiple tables, but remember that the correlation between the dimension tables and only one cannot have multiple, let's look at an example.Now we have created a dimension customer, because the attributes in that dimension use the fields of the geography table in a

Analysis Management Objects (AMO) is the object model library of SQL Server SSAS. It allows you to conveniently access and control Objects in SSAS, including Cube, DataSource, performanceview, Partition, Measure, dimension, Assembly, Role, and DataMining objects. To use it, you must find the SSAS installation path \ MicrosoftSQL Server \ 90 \ SDK \ Assemblies on

IIS7 Configuring SSAS to install the environment over HTTP remote connectionOperating system: Windows7, Windows Server2008IIS version: 7.5IIS7 configuring SSAS for remote connections over HTTP is detailed in the following steps:1. First find the following directories and files in the SQL Server installation directory of the Analysis servers, with the following path: D:\Program Files\Microsoft SQL Server\msa

change history as SCD and hope to realize self-service BI in the way of the UDM, is there any good idea to solve the efficiency problem of this kind of analysis in SSAS? My answer may not be right for everyone, but it's very meaningful to have a little bit of inspiration for you, or you might want to discuss it with a better plan.Let's take a look at how traditional bi write SQL does this kind of analysis, first of all, make it clear that the OLTP li

Analysis Management Objects (AMO) is the object Model Library of SQL Server SSAS, which allows easy access to and control over objects in SSAS, including Cube,datasource, DataSourceView, Partition, Measure, Dimension, Assembly, role, and DataMining objects. To use it, you must locate the SSAS installation path MicrosoftSQL server90sdkassemblies on the machine, Th

Generally, SSRS is used to create reports based on relational data sources. This is basically the end of various technical books. Few reports based on SSAs data sources are introduced. As a result of the project's needs, I have come into contact with this content. Here I will introduce how to establish SSAs-based reports in reporting services based on some of my experiences in the project, and how to use pa

Original: SSAS Series-"05" Multidimensional data (programming architecture)1. What is AMO?Translation: Amo is a complete collection of management classes in SSAS, which we can find in "\100\sdk\assemblies\analysisservices.dll" under the Microsoft.analysisservices namespace. With Amo we can delete and modify cube, dimensions, Mining structure,analysis Service Database,amo not be able to retrieve data, we mus

Original: SSAS Series--"03" Multidimensional data (Cube object)1. What is cube?A simple Cube object consists of basic information, dimensions, and measure groups. Basic information includes the name of the cube, the default measure for the cube, the data source and storage mode, and so on. Dimensions are the actual dimension groups used in the cube. All dimensions must be defined in the dimension collection of the database before they can be reference

1. create a data source (required) and set the connection to the Data Warehouse that may be used in the project. Generally, the Data Warehouse is configured with identity simulation. If the warehouse and SSAS are a server, you can directly use the service account. Otherwise, you can specify a specific user name and password. 2. create a data source view (required) which includes some dimension tables and 1. create a data source (required) and set the

SSRS and SSAS are supported by VB, and custom code is actually only supported by VB, or other languages can be encoded into DLLs and then use. The following is the official VB function library, basically can be used, preserved and duly completed.Https://msdn.microsoft.com/en-us/library/ms157328.aspxHttps://msdn.microsoft.com/library/c157t28f.aspxIn fact, we generally use in SSRS and SSAS are more than a few

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 ana

Original: SSAS Series--"02" Multidimensional Data (Dimension object)1. What is dimension? In mathematics, it is called a parameter, which is the number of independent space-time coordinates in physics. 0-Dimensional is a point, 1-dimensional is a line, 2-dimensional is a long and wide (or curved) area, 3-dimensional is 2-dimensional plus the height to form the volume surface. In physics, Time is the fourth dimension, unlike three spatial dimensions, i

I. Analysis Services　　 Analysis Services is a data engine used for decision support and BI solutions. It provides analysis data used in reports and clients. It allows you to create a high-performance query structure, business logic, and KPIs (Key Performance Indicators of an enterprise) in a multi-purpose data model. This data model can be accessed by any client program that supports analysis services as a data source. Create a multi-purpose data model: use SQL server data tools and select a tab

Roles Before discussing how the newly created role affects the xmla code of the oalkaline database, let's briefly describe the role in SSAs. The following is a role editing interface. Although it has seven option configuration interfaces (not discussed about the mining structure Interface), all of them can be classified into three categories: 1.Read defined Permissions A person with this permission can connect to the OLAP database, and then it wi
