Hands-On Exercise 2: Prepare for future exercises

Download the ORDERS_SRC dump file by opening a terminal and executing:

wget http://dl.dropbox.com/0/view/77gp8zjcqp5h0fl/Collaborate%2010/

orders_src.dmp

Create the ORDERS_SRC user:

sqlplus / as sysdbaSQL> create user orders_src identified by password;SQL> grant connect, resource to orders_src;

Import the ORDERS_SRC schema:

imp orders_src/password file=orders_src.dmp full=y

Prepare for the external table demonstration later:

Create a directory on your PC, and note its location. For this example, we will use adirectory called/home/oracle/Source_Data. Move into this directory and then pull downthe customers_csv file:

wget http://dl.dropbox.com/0/view/kcxnc6z9g93x2ez/Collaborate%2010/customers_csv

Hands-On Exercise 8: Creating Relational Objects

In this exercise, you will create three tables to hold data on customers, orders andproducts. Later on, you will map data in to these tables before loading them in to your

data warehouse.

Locate the TRAINING_STGOracle Database module in your project, expand it andlocate the Tablesentry.Right click on the Tables entry and select New Table.

Enter the name STG_PRODUCTS and clickOk.A new tab will open, allowing to enter details on the newly create table.

Using the Columnstab, enter the following column details:

Name Data Type Length Precision Scale Not Null

PROD_ID NUMBER 6 0 !

PROD_NAME VARCHAR2 20 !

COLOUR VARCHAR2 20

PRICE NUMBER 10 2

COST NUMBER 10 2

PROD_TYPE_ID NUMBER 6 0

PROD_TYPE_DSC VARCHAR2 20

Hands-On Exercise 9: Deploying Relational Objects

In this hands-on exercise, you will deploy the tables and external table that you designed

in the previous exercises.SQL> grant create any directory to training_stg;SQL> grant drop any directory to training_stg;

Using Oracle Warehouse Builder, select Tools> Control Center Managerto start theControl Center Manager application.Locate the TRAINING_STG_LOCATION1entry in the list of locations, expand it, andthen expand the TRAINING_STGmodule to display the list of objects that it contains.Click on and select the TRAINING_STGmodule, as shown in the figure below.

Click on the Default Actionsbutton on the right-hand side of the Control CenterManager, to set the Deploy Action for each of the selected objects to Create.Since none of the objects have been previously deployed the deployment action is set toCreatefor all objects.




22/26

From the application menu, select File> Deploy> To Control Center.

When prompted to register the TRAINING_STG_LOCATION1 location, enter thepassword and click Test Connectionto check the connection details are valid. Onceconfirmed, press OKto save the location details, and then check that the deploymentwas successful (see below) before proceeding.

Once you have checked that the tables have been deployed correctly, close the ControlCenter Manager and return to the Design Center.

Hands-On Exercise 10: Creating Data Mappings

In this first mapping, we will take data from the source PRODUCT, PRODUCT_DETAILSand PRODUCT_TYPES tables, join them and load the results in to the

STG_PRODUCTS table.In the Project Explorer, within the TRAINING_PROJECT, expand the DatabasesandOracleentries. locate the TRAINING_STG module and the Mappings folder within it.Right-click on the mappings folder and select New Mapping.Call the mapping MAP_STG_PRODUCTSIn the mapping editor, locate the Component Palette. If not found it can be opened bychoosing View->Component Palette.Drag and drop a Table Operator on to themapping canvas. Using the Add Table Operator dialog, select the PRODUCTS table fromwithin the ORDERS_SRC module. Repeat the process to add the PRODUCT_DETAILSand PRODUCT_TYPES tables.

Note that you can multi-select these 3 files at once as well.

Using the mapping operator palette, drop a Joiner operator on to the mapping canvas, tothe right of the three tables you just added.

Double-click on the Joiner operator and select the Groups.

Rename INGRP1 and INGRP2 to PRODUCTS and PRODUCT_DETAILS respectively.

Add a 3rdinput group called PRODUCT_TYPES.

Rename OUTGRP1 to STG_PRODUCTS, like this:




24/26

Press OK to save the details.On the mapping canvas, select the INOUTGRP1 entry in the PRODUCTS table, anddrag and drop it on to the PRODUCTS group in the Joiner operator. Do the same withthe PRODUCT_DETAILS table, dragging its INOUTGRP1 column on to thePRODUCT_DETAILS Joiner group, and drag the PRODUCT_TYPES header on to thePRODUCT_TYPES joiner group, like this:

Single-click on the Join operator, and then click in the Join Conditionproperty in theProperty Inspector (if not open it can be opened usingView->Property Inspector).Press the ellipses button () to bring up the Expression Builder.

Using the Expression Builder, join the three input tables in the following way:

PRODUCTS.PROD_TYPE_ID = PRODUCT_TYPES.PROD_TYPE_IDand




25/26


26/26

Select File> Validatefrom the menu or click its corresponding icon in the toolbar tocheck that the mapping is valid, and then save and close the mapping.

Before we can deploy this new mapping to the database, we need to ensure that theTRAINING_STG user you created previously can access tables in the ORDERS_SRCschema. Normally, your DBA would grant access to these tables individually, but for now,the course instructor will connect to the database as the SYSTEM user and grant theSELECT ANY TABLE role to the TRAINING_STG account.

SQL> grant select any table to training_stg;

Using the Control Center Manager, deploy the new mapping to the database, and ensure

that it compiles and deploys correctly.Still within the Control Center Manager, select in turn each of the mappings, right-click onthem and select Start.
