# 1 Data warehousing tool in the market

Data warehousing:

To understand and appreciate the concept of Data warehousing, the following topics needs to be discussed:

• Traditional Databases (RDBMS Concepts)

• Advantages and Disadvantages

• Online Transaction Processing Systems (OLTP)

• OLTP reporting (transactional reporting)

SAP BW 7.3

Traditional database:

TRANSACTION DATA

•Database is defined as an organized collection of data

Typical Scenario- An user/customer makes a transaction and the transaction data is stored in the database

Benefits of a traditional database:• Quicker and easier Data manipulation (Inserts/Deletes/Updates)• Designed for storing transactional type data• Faster transactional reporting

Example of a transactional database Bank Transaction

Online TransactionBank

Transactional Database

Account # Date Transaction Amount

100 01/01/2013 Deposit 10000

100 01/31/2013 Withdrawal 5000

Bank transaction scenario

Online Transaction Processing System (OLTP)

Account # Date Transaction Description Amount

100 01/01/2013 Deposit Pay stub 10000

100 01/03/2013 Deposit Rent 1000

100 01/10/2013 Withdrawal Groceries 500

100 01/15/2013 Check Payment Electricity Bill 100

100 01/31/2013 Withdrawal Restaurant 50

Transactional Reporting (Examples) 1. What is my bank transactions for January 2013 ?

2. How many deposits made in January 2013 ?

Database

3. How is my spending this January 2013 compared to January 2012?

4. Trend reporting for all restaurant based transactions?????

Transactional Database Not Suitable for:• Intelligence based reporting (Analytical Reporting)

• Trend Reporting (Year to Date, Month To Date)

• Multi Dimensional analysis

• Forecasting & Planning

• Analyzing Historical data

Reasons:• Database structured for transactions

• Highly normalized

• Less Volume (Typically 60 days)

• Database uses Entity Relationship modeling

Intelligent/Analytical Reporting• Transactional Database structure prevents analytical type reporting

• To overcome this limitation, the database structure needs to be modified

Database ( Data Warehouse)

Traditional database Data Warehouse

Data Warehouse (Definition)

• Commonly referred to as “Decision Support System”

• Database structure used for reporting and data analysis

• A central repository of heterogeneous data from different sources

• Typically contains Current and historical data (Large Volume)

• Uses Multi Dimensional Modeling

Why use SAP BW as the Data warehouse tool?

• To know the advantages of SAP BW, we need to understand the different categories of Data warehousing (DW) tools available in the market

•Leverage traditional database (In house resources)

•Mix and Match (Using 3rd party tools)

•End to End DW tool

DW Categories:

Leverage traditional database (In house resources)• Use existing resources (Traditional databases, Modeling tool) already available in the organization• Typically smaller companies use this approach

Advantages:1. Low cost (using existing resources)

Oracle DB

MS SQL DB

Create a structure similar to

DW

Use In house

modeling resource (Limited Func.)

Disadvantages

•Create the Data warehouse from scratch •Time to deliver the product is very long (Life cycle

development process)•Lose competitive edge over competitors4. Scalability issues to new data sources

In house reporting

Mix and Match (Using 3rd party tools)• Buy additional 3rd party tools for Modeling, ETL , and Reporting

Oracle DB

MS SQL DB

Disadvantages

•Expensive to buy several 3rd party tools•Maintenance/Upgrade very time consuming and expensive•Data compatibility with different source not guaranteed4. Data integrity issues

Customized Data warehouse (3rd party)

CA ERWIN tool for Modeling

Informatica for ETL

Oracle DB

Cognos for reporting

Advantages1. Need not create DW from scratch

End to End DW tool (SAP BW)• DW product that provides Modeling, ETL, and Reporting capability all in one

Oracle DB

MS SQL DB

Advantages

•Need not create the DW from scratch•Already prepackaged with industry specific modules•Time to product delivery is very quick ( Shorter Life cycle)4.Compatible with almost all sources (SAP, Non SAP)5. Data integrity (SAP is market leader in ERP)
