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

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

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. Modeling tools and key processes The purpose of the modeling of

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

Tags: style blog http OS Io strong data Dimension optimization In the process of SSAs development and design, dimension optimization is very important because it plays a very important role in the process of SSAs analysis service performance optimization. Generally, the first step to optimize the performance of a cube is to view the dimension and observe the design of the attribute relationship in the dim

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

, you can perform the MDX query. We will discuss the usage of the MDX statement in detail in later sections. Here we only show a few simple examples. First, you need to know several keywords, such as select XXX from XXX Where xxx, which has the same meaning as SQL. The new concept is "row" and "column. Query statement where the date is column and the IP address is row Query statement where the date is a row and the IP is a column Query statement with Filter Mdx is not difficult, but it

1. Local multi-dimensional dataset The local multi-dimensional dataset and local mining model allow you to analyze the workstation when the client workstation is disconnected from the network. When interacting with a local cube, admod. NET and analysis management objects (AMO) will also load the local cube engine. Only one process can access the local cube file, because the local cube engine will exclusively lock the local cube file when establishing a connection to the local cube.A process can

Introduction to RolesBefore discussing how the newly created role affects the XMLA code of the Oalp database, we start with a brief description of role in SSAS. Here is one of the character editing interfaces, although it has 7 options to configure the interface (not to discuss the mining structure interface), but in fact all can be categorized into 3 categories:1. Read the defined PermissionsSomeone with that permission can connect to the OLAP databa
