ssas表格模型权限控制_创建第一个SSAS表格模型数据库

ssas表格模型权限控制

Considering BI environment, when comparing Multidimensional Vs Tabular model databases, both of them have their own advantages and purpose in data analytics and business intelligence.

考虑到BI环境，在比较多维VS表格模型数据库时，它们在数据分析和商业智能方面都有各自的优势和目的。

The best way to learn about SSAS Tabular model databases is to perform research, experiment a bit and build one, yourself. In this article, we’ll do just that and I’ll provide detailed information on building simple and modestly populated Tabular database for testing/personal usage.

了解SSAS表格模型数据库的最好方法是自己进行研究，进行一些试验并构建一个数据库。在本文中，我们将这样做，并且将提供有关构建简单且数量适中的表格数据库以供测试/个人使用的详细信息。

1. Requirements

1. 要求

SQL Server 2012 or higher, with installed Analysis Services instance in Tabular mode
SQL Server 2012或更高版本，以表格模式安装了Analysis Services实例

Quick note: In SQL Server 20xx installation, Analysis Services instance deploys Multidimensional mode by default.

快速说明 ：在SQL Server 20xx安装中，Analysis Services实例默认情况下部署多维模式。

SQL Server Data Tools (SSDT) 2013 or higher
SQL Server数据工具（SSDT）2013或更高版本
Deployed AdventureWorksDW sample database 2012 version or higher (this article regards the 2014 version) as data source
将已部署的AdventureWorksDW示例数据库2012版本或更高版本（本文视为2014版本）作为数据源
SQL Server Management Studio (SSMS) 2014 or higher;
SQL Server Management Studio（SSMS）2014或更高版本；

2. Creating a blank project in SSDT

2. 在SSDT中创建一个空白项目

To start building a Tabular model database, the first step is to create a project file (Analysis Services Tabular Project), giving the name to the project (in this article, it is MyFirstTabularDatabase), define the custom location or leave the default, and the Solution name will be the same as the name of the project, by default.

要开始构建表格模型数据库，第一步是创建一个项目文件（ Analysis Services Tabular Project ），为该项目指定名称（在本文中为MyFirstTabularDatabase ），定义自定义位置或保留默认位置，然后默认情况下，解决方案名称将与项目名称相同。

Note: The solution name can be defined independently from the project name.

注意：可以独立于项目名称定义解决方案名称。

After that, this dialog will appear:

之后，将出现以下对话框：

The exact name of the SSAS Tabular instance must be input into the Workspace server text field, otherwise, it won’t be possible to create a project. To make sure the connection is valid, press ‘Test Connection’ button. After validation, if successful, message states:

必须将SSAS Tabular实例的确切名称输入到Workspace服务器文本字段中，否则，将无法创建项目。为了确保连接有效，请按“测试连接”按钮。验证后，如果成功，则消息指出：

Also, the Compatibility level must comply with installed version of Analysis Services instance.

另外，兼容性级别必须符合Analysis Services实例的安装版本。

When a blank project file is made, the environment looks like this:

制作空白项目文件时，环境如下所示：

The most important part of this project is Model.bim, which is the skeleton of the future SSAS Tabular model database. In further steps, this file will be populated with necessary elements and, in the end, deployed into Analysis Services instance.

该项目最重要的部分是Model.bim ，它是未来SSAS表格模型数据库的框架。在进一步的步骤中，将使用必要的元素填充此文件，最后将其部署到Analysis Services实例中。

Note: Because of certain number of steps and actions, every change performed should be saved with Save All (instead of Save)

注意：由于某些步骤和操作的数量，执行的每个更改都应使用“ 全部保存” （而不是“保存”）保存

3. Importing data into the SSAS Tabular model database

3. 将数据导入SSAS表格模型数据库

To begin, populate the Tabular model; importing data into the project is the next step. That means selecting the data source (mentioned in Requirements), as a preparation, rename and filter objects (tables) within data source and import prepared tables into the model.

首先，填充表格模型；下一步是将数据导入项目。这意味着选择数据源（在需求中提到）作为准备，重命名和过滤数据源内的对象（表），并将准备好的表导入模型中。

Select the option ‘Import from Data Source’, placed in Model menu, and Table Import Wizard shows. In this article, the source connection will be Microsoft SQL Server.

选择位于“模型”菜单中的“从数据源导入”选项，然后将显示“ 表导入向导” 。在本文中，源连接将是Microsoft SQL Server 。

Info: There are numerous internal and external sources besides mentioned (Oracle, Teradata databases etc.), and that is one of the advantages of deploying and using SSAS Tabular databases, compared with only-internal OLE DB sources support for Multidimensional model databases.

信息：除了提到的（Oracle，Teradata数据库等）之外，还有许多内部和外部资源，与仅内部OLE DB源对多维模型数据库的支持相比，这是部署和使用SSAS表格数据库的优势之一。

In the Server name text field, select the proper Database Engine instance, where data source is deployed. After selecting, the list of databases will appear in Database name drop-down menu. This connection must be also validated.

在服务器名称文本字段中，选择适当的数据库引擎实例 ，在该实例中部署数据源。选择后，数据库列表将出现在“ 数据库名称”下拉菜单中。此连接也必须经过验证。

Note: This article will use Windows authentication, although there is option to select Service Account. This method is Impersonation.

注意：尽管可以选择服务帐户，但本文将使用Windows身份验证。此方法是模拟。

In picture above, there are two methods of importing data, through querying the tables (intermediate knowledge of T-SQL is required) or selecting from the tables list (easier and used in this article).

在上图中，有两种导入数据的方法，即通过查询表 （需要T-SQL的中级知识）或从表列表中进行选择 （本文中较为轻松和使用）。

3.1. Filtering and renaming the tables

3.1。 过滤和重命名表

Next step is filtering and renaming the necessary tables from the data source, and finalizing the process of data importing:

下一步是从数据源过滤并重命名必要的表，并完成数据导入过程：

Check the tables as shown in the picture (tables are selected for illustrating reasons). Renaming tables performs by double-clicking particular cells in Friendly Name column; in the other words, simplifying the table names, de-normalizing, in sense of CamelCase or pascalCase normalization.

如图所示检查表（选择表是为了说明原因）。重命名表的方法是双击“ 友好名称”列中的特定单元格；换句话说，就CamelCase或pascalCase规范化而言，简化表名，取消规范化。

All of the selected tables must check with Preview & Filter function:

所有选定的表都必须使用“ 预览和过滤器”功能进行检查：

As shown in this picture above, the table DimCustomer needs filtering (the friendly name for this table will be applied later), by unchecking the redundant columns. In this case, the redundant columns are related to translated columns that resembles the column e.g. EnglishEducation (like SpanishEducation, HebrewDescription etc.). This applies for all of the tables, separately. The purpose of filtering is reducing the size of the future Tabular database, which will improve its performance.

如上图所示，表DimCustomer需要过滤（通过取消选中冗余列来过滤此表的友好名称）。在这种情况下，冗余列涉及类似于柱例如EnglishEducation（如SpanishEducation，HebrewDescription等）翻译列。这分别适用于所有表。过滤的目的是减小将来的表格数据库的大小，这将提高其性能。

Table FactInternetSales (with Friendly Name Internet Sales) needs removal of particular columns: OrderDateKey, DueDateKey, ShipDateKey.

表FactInternetSales度 （与友好名称互联网销售 ）需要去除特定的列：OrderDateKey，DueDateKey，ShipDateKey。

Important notice: Until the tables are reviewed, properly renamed and filtered, ‘Finish’ button should not be pressed, because there will be a lot of redundant data, and the Tabular model database itself may be larger than expected.

重要说明：在检查表，正确重命名和过滤表之前，不应按下“完成”按钮，因为将有很多冗余数据，并且表格模型数据库本身可能比预期的大。

After clicking ‘Finish’, and importing process is done, this information should appear:

单击“完成”并完成导入过程后，此信息应显示：

Troubleshoot: if error occurs, check the Impersonation option again, and make sure that Windows authentication credentials are valid, or provide the necessary Login object within AW2014 database.

疑难解答 ：如果发生错误，请再次检查“ 模拟”选项，并确保Windows身份验证凭据有效，或在AW2014数据库中提供必要的Login对象。

3.2. Renaming the columns and verifying a Date dimension table

3.2。 重命名列并验证“日期”维表

After renaming and importing the tables into Model.bim, the columns in these tables also must get the Friendly Names. Imported tables are placed in tabs, as shown in the picture.

将表重命名并导入到Model.bim中之后，这些表中的列也必须获得友好名称。导入的表放置在选项卡中，如图所示。

Perform these steps in order to correctly rename all columns in every table:

执行这些步骤为了正确地重命名每个表中的所有列：

Renaming of the columns is performing by double-clicking the header of the particular column (as shown in the picture), or by change the Column Name field in Properties (column FirstName -> First Name e.g.).
列的重命名是通过双击该特定列的标题（如在图中所示），或通过改变列名称字段在属性进行（柱姓 - > 名字例如）。
Columns that contain “-Key” in title should be changed with “Id” (CustomerAlternateKey -> Customer Alternate Id, e.g.)
标题中包含“ -Key”的列应更改为“ Id”（例如， CustomerAlternateKey- > Customer Alternate Id ）
Some of the columns must get specific names:
一些列必须获得特定名称：

Note: FullDateAlternateKey column in Date table must get title “Date”, because if doesn’t, the structure of the Tabular model database will be compromised.

注意：Date表中的FullDateAlternateKey列必须具有标题“ Date”，因为如果没有，则将损害表格模型数据库的结构。

While renaming of the columns is in process, creation of the Date dimension table can also take place. Make sure that Data type of Date column (formerly FullDateAlternateKey) is like shows in Properties:

在重命名列的同时，还可以创建“ 日期”维表 。确保“日期”列的数据类型（以前为FullDateAlternateKey）类似于“属性”中的显示：

After that, select the Date column (if not checked) and click the option Mark as Date table (in Table menu). Make sure that column as a unique identifier is Date in following dialog:

之后，选择“日期”列（如果未选中），然后单击“ 标记为日期表 ”选项（在“ 表”菜单中）。在以下对话框中，确保该列作为唯一标识符为Date：

At this moment, there are now populated Tabular model databases with a verified Date dimension table.

现在，现在已经填充了带有经过验证的日期维度表的表格模型数据库。

Next steps are creating the particular elements of Tabular database: Relationships, Calculated column, Measures, KPIs, Perspective, Hierarchies, Partitions, administrative Role, and finally, deploy the SSAS Tabular model database.

下一步是创建表格数据库的特定元素：关系， 计算列 ，度量， KPI ， 透视图 ， 层次结构 ，分区， 管理角色，最后部署SSAS表格模型数据库。

4. Creating the specific elements of SSAS Tabular model database

4. 创建SSAS表格模型数据库的特定元素

For certain steps in process, it is necessary to switch to Diagram View (Model View option in Model menu), as shown in picture below:

对于正在进行的某些步骤，有必要切换到图视图 （“模型”菜单中的“模型视图”选项），如下图所示：

Note: there are two small icons in the right-down corner, for switching these two views

注意：右下角有两个小图标，用于切换这两个视图

4.1 Creating Relationships

4.1 建立关系

Notice that some relationships already exists in this table, and they must be checked through Manage Relationships option (in Table menu):

请注意，此表中已经存在一些关系，必须通过“ 管理关系”选项（在“表”菜单中）检查它们：

If some of these relationships are missing, add them within Manage Relationships modal dialog, clicking the Create button, where the related tables and columns define:

如果缺少其中一些关系，请在“管理关系”模态对话框中添加它们，单击“创建”按钮，其中相关的表和列定义：

or with drag-and-drop method, as shown:

或使用拖放方法，如下所示：

Note: the particular column must be selected at first, and then dragged to related column.

注意：必须首先选择特定的列，然后将其拖到相关的列。

With the chosen method, create three new relationships, in this particular order (tables are with bigger font, and columns are with smaller):

使用选择的方法，以这种特定顺序创建三个新的关系（表的字体较大，而列的字体较小）：

After creating these relationships, one full and two dotted line will appear (because of specified order):

创建这些关系后，将出现一条完整的虚线和两条虚线（由于指定的顺序）：

Verify that all of the relationships are here:

“计算列1”将出现在左侧，然后输入公式（本文中存在的所有公式都是简单的DAX公式），如下所示：

The populated column should appear when finished with input, and rename the column into Month Calendar.

输入完毕后，将出现填充的列，并将该列重命名为Month Calendar 。

After this, create Day of Week calculated column, with repeating previous steps on Day of Month column:

之后，创建“星期几”计算列，并在“月数”列重复前面的步骤：

In Product table, create two calculated columns, with corresponding formulas:

在“ 产品”表中，创建两个具有相应公式的计算列：

Product Subcategory Name:

产品子类别名称 ：

Product Category Name:

产品类别名称 ：

In Internet Sales table, create Margin calculated column, besides Tax Amt column:

在“ Internet销售”表中，除了“ 税额”列之外，创建“ 保证金计算”列：

Note: The reason for this particular placing of calculated columns is because of related data between the columns

注意：之所以要特别放置计算列，是因为列之间的相关数据

4.3. Adding Measures
