Business Intelligence Basics


Some time ago, we were about to start development of a BI tool on top of Apache OFBiz™. OFBiz already comes with a normalized transactional database and some dimensional modeling, so we started our BI process by focusing on the concept of Data Warehousing for Business Intelligence. One of our primary reference books was “The Data Warehouse Toolkit: The Complete Guide to Dimensional Modeling by Ralph Kimball, Margy Ross“. This book gave us a great head start in our development efforts, and in this post we wanted to share a quick overview of some of the things we learned during our effort.


Business Intelligence (BI) is nothing but the concepts and methods to improve business decision making by using a fact-based support system. Often, BI applications use data gathered from a data warehouse or data-mart.


A Data Warehouse (DW) is a copy of the transactional data to facilitate decision making. However, not all data warehouses are used for BI, nor do all BI applications require a data warehouse. Data preparation and data usage are two separate (but closely linked) segments of the BI architectural stack.


One of the most important assets of any organization is its information. This information is kept in two forms:
1. The operational systems of record (Transactional)
2. The Data Warehouse (Reporting)

Operational systems are where data is put and the data warehouse is where we get the data out.

Data Warehouse Purpose

1. Organization’s information is easily accessible.
2. The contents in the Data Warehouse need to be labeled meaningfully.
3. The tool that accesses the data warehouse must be simple and easy to use. They also must return query results to the user with minimum wait times.
4. Organizational information is presented consistently i.e. high quality information.
5. Effective control of access to the organization’s confidential information.
6. It is the foundation for improved decision making.
7. It has the right data to support decision making.

Applications in an Enterprise

BI can be applied to the following in order to drive business value:
1. Measurement
2. Analytics
3. Reporting/Enterprise Reporting
4. Collaboration Platform
5. Knowledge Management
6. Alerts/Alarm function

How and Where to Start

It is very important that the personnel who participate in the project have a vision and an idea of the benefits and drawbacks of implementing a BI system. A well designed BI solution provides a consolidated view of key business data not available anywhere else in the organization, giving management visibility and control over measures that otherwise would not exist. Without proper data, or with too little quality data, any BI implementation fails. Before implementation, it is a good idea to do some data profiling. This analysis identifies the content, consistency, and structure of the data. The important steps of a BI implementation include but are not limited to:
1. Go through the business data source in order to collect the needed data.
2. Convert business data to information and present it appropriately.
3. Query and analyze data.
4. Act on the data collected.

Consideration must be made in order to successfully integrate BI systems into any company. The BI system that you build must be accepted and utilized by the users in order for it to add value to the organization. If the system doesn’t add value to the user’s mission, they simply don’t use it. Taking a user-centered approach throughout the design and development stage may further increase the chance of rapid user adoption of the BI system that you developed.

These were some basics around DW and BI, we will see more details in our upcoming posts. In the mean time you can surely refer to the book “The Data Warehouse Toolkit: The Complete Guide to Dimensional Modeling by Ralph Kimball, Margy Ross” which has helped us and will likely help you too.

Thanks for taking the time to read this post.

Keep Learning…
