This module provides you with an introduction to Microsoft® SQL Server™

2000 Analysis Services

The objective of the module is to give you a comprehensive introduction to cube building fundamentals by using the Analysis Manager wizards, which include the Cube Wizard and the Dimension Wizard

After completing this module, you will be able to:

! Describe SQL Server 2000 Analysis Server components

! Navigate through the basic interfaces of Analysis Manager

! Prepare to create a cube by reviewing data sources and initiating the Cube Wizard

! Create an online analytical processing (OLAP) cube by using the Cube and Dimension Wizards

In this module, you will learn

about the fundamentals of

cube building within

Analysis Manager

The following are the product definitions for Analysis Services:

Microsoft OLAP and data mining product that ships with SQL Server 2000 and includes the server and client software

Server contains an OLAP engine and a data mining engine that runs as a service under Microsoft Windows® 2000, or Microsoft Windows NT® with Service Pack 5 or later The Analysis Server service is called

MSSQLServerOLAPService

Analysis Manager runs under Windows 2000 and Windows NT

referred to as PTS PTS runs under Windows 2000, Windows NT, Microsoft Windows 98, and Microsoft Windows 95 PTS is different from Microsoft Excel PivotTables®

Topic Objective

To define commonly used

terms

Lead-in

Before creating databases

and cubes by using the

Analysis Manager, you must

understand fundamental

terms applicable to Analysis

Services

Previewing Analysis Manager

Analysis Manager is the interface for designing and administering Analysis Server databases and cubes It is a snap-in application in Microsoft

Management Console (MMC), a common interface for hosting administrative tools Analysis Manager contains various panes and menus that assist you in administering Analysis Server objects

Console Tree View

The tree view in the left pane of MMC, also referred to as the console tree, is the primary means for navigating Analysis Manager

Each level of the tree contains folders, OLAP objects, or both The Analysis Servers folder displays a list of servers that are available to you Because only one server can run on a single computer at a time, each server displays the name

of the computer running it

The server name acts as a folder for OLAP databases on that server Each Analysis Server can contain one or more databases Databases can manage one

or many cubes Shared components such as dimensions, roles, and data sources are also stored at the database level

The following folders are found under each OLAP database folder:

Manager and to explain all

of the major interface

components

Lead-in

Analysis Manager is the

user interface for designing

and administering Analysis

Server databases and

cubes

Delivery Tips

Note that more than one

server may appear below

the Analysis Servers folder

When performing the

demonstration, ensure that

students log on to the

Analysis Server located on

their own computers

Deliver these materials

while performing an informal

demonstration of the

Analysis Manager

Stress the usefulness of

right-clicking In Analysis

Manager, when you want to

perform actions on server

objects, you usually do so

by right-clicking the object

Do not spend too much time

on the data pane at this

point Using the data pane

for browsing data is covered

more thoroughly later in the

module

Menu System

You have access to several menus in Analysis Manager and MMC MMC

snap-in applications such as Analysis Manager have two levels of menus

The top-level menusConsole, Window, and Helpbelong to MMC itself and do not apply to the current snap-in application

The second level of menus is actually a toolbar This toolbar contains the

Action, View, and Help menus, which are specific to the current MMC snap-in

applicationin this case, Analysis Manager

The Action menu, which contains most of the functionality, is

context-sensitive In other words, the commands that appear on the menu change depending on the object you select in the tree view The same commands that

appear on the Action menu also appear on a shortcut menu displayed by

right-clicking an item in the tree view

Metadata View

The details pane can display a metadata view, which is a convenient technique

to review statistics about databases, cubes, and dimensions

The metadata view is context-sensitive The information that is displayed is dependent on the folder that is selected in the Tree view For example, at a particular cube level, dimensions, measures, and cube size are among the elements available in the metadata view

Data Pane

The data pane enables you to browse the data of your cubes This view is accessible only at the cube level

The details pane displays the Getting Started, Metadata, and Data tabs

only when HTML mode is enabled To enable or disable HTML mode on the

toolbar, click View and then click HTML

Note

# Preparing to Create a Cube

! Reviewing the Data Source

! Setting up the OLAP Database

Before you develop a prototype cube, you review the data source that was used

to build the cube You must also understand how to create the OLAP database that contains the cube, as well as all of the related cube objects

Topic Objective

To introduce the topics that

this section covers

Lead-in

Before you develop a

prototype cube, review the

data source used to build

the cube

Delivery Tip

Use this slide simply to

introduce the bullets on this

slide Cover the two

sections when you arrive at

the next two slides

Reviewing the Data Source

You base the cube created in this module on a SQL Server database called

Module 02 The database is a scaled-down version of the Foodmart 2000

database that is included with Analysis Services

The Module 02 data warehouse is small and uncomplicated so that you can

easily describe its structure This database illustrates basic dimension types

For more information about different types of dimensions, see module 4,

“Setting up Dimensions”, in course 2074A, Designing and Implementing OLAP

Solutions with Microsoft SQL Server 2000

Module 02 Database Structure

The preceding diagram illustrates the structure of the Module 02 database, which consists of a single fact table: SalesFact

The SalesFact table has four dimension keys:

To introduce the Module 02

database, which is used as

the data source for the

cube

Lead-in

The cube that you will

create in the module is

based on a simple SQL

Server database

Delivery Tip

You can present the tables

and keys by using the slide,

or you can open SQL Server

Enterprise Manager directly,

connect to the Module 02

database, and open the

Module 02 Schema

Fact Table and Dimension Table Relationships

The following describes how the fact table and dimension tables are used to create the cube dimensions:

! The State_ID key is joined to a single dimension table, creating a star

schema dimension

! The Product_ID key is joined to a chain of dimension tables, creating a

snowflake schema dimension

! The Employee_ID key is joined to the Employee dimension table, creating

a parent-child dimension

! The Month key will create an entire hierarchy by using the Dimension

Wizard

Setting Up the OLAP Database

! Creating the New Database

! Starting the Cube Wizard

! Specifying a Data Source

You must set up an OLAP database before designing and building a cube An OLAP database in Analysis Services is a collection of cubes and related cube

objects After creating an OLAP database, you can begin creating the Module

02 database cube by starting the Cube Wizard

The first table to assign in the Cube Wizard is the fact table To assign a fact table for a cube, you must specify a data source for the database To do so, you

refer the Analysis Server Module 02 OLAP database to the SQL Server

Module 02 database

Topic Objective

To explain how to create a

new OLAP database and to

prepare for the creation of

the Module 02 database

cube

Lead-in

You must create an OLAP

database before designing

and building a cube

Demonstration: Preparing to Build the Sales Cube

In this demonstration, you will learn how to perform the tasks that are performed before building an OLAP cube You will connect to the Analysis Server, define an OLAP database, and specify the data source for the cube

! To verify that the Analysis Server is running on your computer

1 Log in to the NWTraders classroom domain by using the data in the

exists and is running in the right pane of the Computer Management window

The status of MSSQLServerOLAPService should indicate Started

6 If the service is not started, right-click MSSQLServerOLAPService, and then click Start

7 Close the Computer Management window

Topic Objective

To demonstrate how to

review the data source for

the cube and create the

OLAP database that

contains the cube
