Steps Need To Perform Data Warehousing Practicals
- 1. B.SC.IT: SEMESTER – VI Steps Need To Perform Data Warehouse Practical’s [CBSGS – 75:25 Pattern] DATA WAREHOUSE
- 2. STEPS NEED TO PERFORM DW PRACTS 1)installing oracle . 2)configuring listener 3)creating Oracle database ACMEDATA with password abcd1234 mounting ACME_POS_DB_Create script to sql server with sql server authentication mode(from 3449_code)authors code Note: after executing this file one user gets created acme_dw_user change password to abcd1234 Note : change settings in sql server , enable sa and set password abcd1234 Execute ACME_POS_DB_Object_script ACME_POS_LOAD_SCRIPT_FILESACME_POS_Bulk_ Load_Data file from cmd for the Sake of adding record to database. Mounting of create_acme_ws_orders.sql file from sql developer Note: Oracle sql developer may ask you java exe path ,select java folder from program files
- 3. 1) new/select Database connection Connection Name:ES Username:sys Password:abcd1234 Role:SYSDBA ServiceName:ACMEDATA(name of our database) Test: Connect: Open file: create_acme_ws_orders.sql Execute all files step by step 2)Create new connection As Connection Name:TT Username:ACME_WS_ORDERS Password:abcd1234 Role:default ServiceName:ACMEDATA(name of our database)
- 4. 4)Configuring Repository Hostname:LOCALHOST Oracle service name:ACMEDATA Create new workspace Username:SYS Password:abcd1234 (select only 2 options rest are adapters) Workspace_owner_name:abc Password:abcd1234 Workspace name:ACMEWORKSPACE Next Enter password for OWBSYS(we have to unlock this account at the time of installation) abcd1234 next,next, finish 5)connecting design center and creating oracle module: Username:abc Password:abcd1234 Host:LOCALHOST
- 5. Service name:ACMEDATA 1) creating oracle module Click on oracle -- new oracle module Name:ACME_WS Edit location : Username:ACME_WS_ORDERS Password:abcd1234 Host:LOCALHOST Service name:ACMEDATA - click on TEST Next,next,finish Right click on ACME_WS - select import - database objects- tables- all tables- next 2) creating non-oracle module 6) creating flat file module File we want to import : counties.csv Design center :
- 6. - MYPROJECT-- FILE - New Flat File Module - Name: counties_mod -- Edit location -browse 3449_code directory After that click next , finish ----------------------------------------------- Now select counties_mod --- Click on Import - Flat file --- select counties.csv file from 3449_code , Next,next , select use first record as field name Finish 7) Creating Target user and Target Module Open design center : Goto Globals Navigator Select security--- Users --- New user - create user
- 7. DBA NAME: SYS DBA PASSWORD: abcd1234 User Name Name: bbc Password: abcd1234 Ok , next,finish New Oracle module: Name: ACME_DW Edit location: Username:bbc Password: abcd1234 Host:LOCALHOST PORT:1521 Service name: ACMEDATA Test Next, Finish
- 8. Unit 2 1) Installation of Oracle 2) Mounting Acme_Pos Data in Sql Server (acme_dw_user abcd1234) 3) Creating Oracle Database (acmedata abcd1234) 4) Mounting Acme_Ws data in Oracle (acme_ws_orders abcd1234) 5) Creating Repository 6) Connecting To Design Center (abc abcd1234) 7) Creating Oracle Module (acme_ws) 8) Creating Non Oracle Module (acme_pos) 9) Creating File Module (Counties_File) 10) Importing Data in File Module Unit 3: 1)Creating Target user (bbc) 2)Creating target module(ACME_DW) 3)Creating date dimension(DATE_DIM) 4)Creating Product dimension(PRODUCT_DIM) 5)Creating Store dimension(STORE_DIM)
- 9. 6)Creating Cube(SALES_CUBE) 1) Creating date dimension(DATE_DIM) Design center - Target module (ACME_DW) --Dimension--New(don’t use new dimension -- Time Dimension(last option) -ok Name:DATE_DIM - ROLAP Fiscal start year :-2007(refer ACME_POS DB) Number of year:3 - Calendar Normal hierarchy select All -Next (Note : along with DATE_DIM it will create DATE_DIM_MAP) PRODUCT DIMENSION
- 10. NEW DIMENSION - STORE_DIM STORAGE: ROLAP Dimension Attribute: ID DESCRIPTION ADDRESS1 size 60 ADDRESS2 size 60 CITY size 50 STATE ZIPPOSTALCODE size 50 COUNTY size 255 Hierarchy Level 1) COUNTRY 2) REGION 3) STORE TYPE 1: (Do not keep History) Creating CUBE Cube New Cube Sales_cube Next
- 11. Dimension Three Dimension (Store , product_Times) Measures:- Name 1.Quantity 2.Sales_amount NEXT FINISH Unit 4 1) Create Stage Area 2) Create Stage Map Open Design Center --- ACME_DW--Table-New Table Name: STAGE_TAB COLUMN SIZE SALE_DOLLAR_AMOUNT SALE_DATE PRODUCT_NAME 50 PRODUCT_SKU 50 PRODUCT_CATEGORY 50 PRODUCT_BRAND 50
- 12. PRODUCT_PRICE PRODUCT_DEPARTMENT 50 STORE_NAME STORE_NUMBER 10 STORE_ADDRESS1 STORE_ADDRESS2 STORE_CITY 60 STORE_STATE 60 STORE_ZIPPOSTALCODE 50 STORE_REGION 50 STORE_COUNTRY 50 STAGING MAP:- MAP NEW MAPPING STAGE_MAP OPEN SQL SERVER NEW DATABASE DIAGRAM ADD TABLE OPERATOR ADD STORE TABLE ADD ITEM TABLE
- 13. ADD REGIONS ADD POS_TRANSACTION SELECT JOINER OPERATOR OPEN DETAILS GROUPS STORE (INPUT GROUP) ITEM (INPUT GROUP) OUTPUT GROUP REGION POS_TRANSACTIONS REGISTER OK Add table operator Register table Link table to input groups Properties Join conditions OK Drag and link each and every table according to specification Column name with STAGE_TAB
