SummaryAt this point, we have introduced the preliminary use of the SSAS-related tools.You need to familiarize yourself with the development interface of SSDT and familiarize yourself with the commonly used MDX syntax (about MDX now you need to do a preliminary understanding, and
have successfully created a cube with SSDT and refined the dimensions. The follow-up will continue to expand around this example.Finally, we summarize the content of this article:1. You need to understand the order in which the wizard creates the cube:Select Creation Meathod (use existing tables)-->select Measure Group Tables-->select Measures-->select New Dimensions-->completing the Wizard2. Structure of the Cube Designer:Contains multiple tabs, each tab containing multiple panes, familiar wit
There was an error deploying an SSAS project to the local server in SSDT You cannot deploy the model because the localhost deployment server isn't running in multidimensional mode. The reason for the error is that I only chose to install tabular mode when I installed SQL Server 2012 locally, and this demo project is a cube project, which is called multidimensional mode in SQL Server 2012. Sometimes the projects we deploy are not necessarily on th
This is a creation in Article, where the information may have evolved or changed. SSA Overview The SSA was introduced in Go1.7, which greatly improved the performance of the compiler, but it also caused some slowdown in the compilation process. Here is a brief description of the SSA and SSA applications, combined with online food and books. The SSA stands for the static single-assignment, which is an IR (middle representation Code), to ensure that each variable is assigned only once. This can he
BI business intelligence training series-(3) Introduction to SSAS and business intelligence ssasIntroduction: A client tool provides the ability to design, create, and manage multidimensional datasets from a data warehouse, and access the OLAP data client. The solution is as follows: Related Concepts: dimensions: Dimensions can be understood as the basis for Division. Simply put, dimensions are the data perspective. A dimension is linked to a databas
SQL Server 2008 R2 created Business Intelligence project projects, and an error occurred while deploying the data cube: OLE DB error: OLE DB or ODBC error: User ' NT authority\network SERVICE ' login failed.; 28000; Unable to open the requested database "AdventureWorksDW" for login. Login failed.; 42000. As shown in the figure: Later, click the Browser tab in the cube, and the error is as follows: After a lot of tutorials, it turns out that the problem is that
There are many ways to operate SSAS databases. Is there a way to perform these tasks automatically through scripts, such as processing partitions, creating backups, and monitoring the running status of SSAS.

The first section briefly introduces powershell, including some basic commands, and how to open powershell and navigate to the SSAS object. The second article explains how to use variables to create SSAs backups based on the current date and how to run the MDX and xmla scripts.

This article describes several solutions of the SSAS database, and briefly introduces the application scenarios of various solutions. Environment conventions: SQL Server 2008 Example Library: Adventure works DW Method 1: process directly in the project This method is often used in the development and testing stages. This method is usually the first full processing. If the SSAS library is sti
How to implement proactive caching in SQL Server Analysis Services (SSAs) 2005Written by: Ray Barley ProblemWe have chosen molap storage in order to maximize the query performance of our cubes. since we have a number of cubes we are now focused on coming up with a strategy for keeping the cubes up to date as the data in our warehouse changes frequently. can you give us the details on how we go about implementing the proactive caching feature in SQL S
1. What is it? SSAS is a component used for SQL Server databases for BI. With SSAS, you can create multidimensional databases and perform data mining on them. This document describes how to analyze SSAS data. Next let's take a look at it. The solutions provided by business intelligence can obtain data from multiple data sources and 1. What is it?
The SSAs dimension attribute (Attribute) has the following three properties: KeyColumn, NameColumn, ValueColumn, as shown in the date dimension of the AW setting for these three column properties, And we use the wizard to generate the dimension by default only KeyColumn settings, if not manually set NameColumn, its value is equal to KeyColumn, if not manually set ValueColumn, its value is the default equals NameColumn. In general, there is no problem
ProblemWhat exactly is SQL Server analysis Services (SSAS) aggregations and how exactly can I review and use them?SolutionAggregations in SSAS offer a wonderful opportunity to improve query performance and calculation times by "pre aggregating" Sets of data. These aggregations allow a cube query to ask for a specific value or set of values for a specific group of dimension Attri Butes (a set), and has the c
There are many ways to deploy the SSAS library. You can select different methods based on different environments. This article lists several of the most common deployment methods and describes their application environments. Environment conventions: SQL Server 2008 Example Library: Adventure works DW Method 1: Visual Studio direct deploy This method is the most direct and simple method. Most of us deploy it locally using this method. If you need to
In the SSAS Data Source view, namecomputation is an SQL expression represented as a computing column. Using name calculation, you can extend the relational architecture of tables or views in the data source view without modifying the tables or views in the basic data source. Some beginners see that named computing is generally defined in DEVStudio of SSAS, which is easy to misunderstand. In the
In many analysis models that do not require real-time data but have massive data volumes or require sufficient flexibility, SSAs has great advantages over traditional SQL, such as performance and user customization. The performance advantage is reflected in the fact that MDX statements are more customizable than SQL Aggregate functions with larger data volumes. In this case, developing a display tool suitable for various users to freely analyze statis
The structure of the cube in SSAS When building the cube and writing MDX in SSAS (SQL Server Analysis Services), it is easy to get confused by some nouns, such as Dimension (dimensions), Measures Dimension (metric dimensions), Measure (Metric), hierarchy (hierarchy), Attribute hierarchy (property hierarchy), Level (rank), cell (unit), member (members), member properties (Members property), Set (set), Turp
The SSAS modeling tools available in the SQL Server 2008 R2 database include the SQL Servers Management Studio and business Intelligence Studio, so what is the modeling process? Here's what we're going to introduce, and let's take a look at the SQL Server 2008 R2 database modeling tools and key processes, as well as data mining, permissions, and access interfaces.

Today, another friend has encountered slow processing speed of the SSAS database, mainly because the data aggregation volume is indeed large and it takes more than thirty minutes to process each time, is there any way to reduce the processing time? I have been engaged in Bi for seven years, so similar questions can definitely be listed in the top 10 FAQ in the career circle. These problems are often a little complicated.
