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

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

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?

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

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

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

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. Here we will list some of our

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

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
