Business Intelligence and Data Warehouse- Match made in heaven

Business Intelligence and Data Warehouse- Match made in heaven

Business Intelligence and Data Warehouse are two separate yet closely linked technologies. These technologies help an organisation to unearth the hidden value in their data.
But before explaining their relationship in detail, let’s first understand what these technologies do!
Business Intelligence is a technology-driven practice that transforms raw data into actionable intelligence. Data Warehouse acts as a middleware in Business Intelligence architecture. It extracts the data from operational databases or external sources. It transforms it into a single format and stores it for further analysis.

Although seems new, the concept of the data warehouse saw its genesis in 1990. It was first introduced by Bill Inmon who is regarded as the father of Data Warehouse. He defined a Data Warehouse as:

“A subject-oriented, integrated, time-variant and non-volatile collection of data that supports management decision- making the process”.

Since then, data warehouses have become an underlying engine of Business Intelligence Implementation.

Importance of Data Warehouse in Business Intelligence

Every organisation has data problems. These problems can be categorised into two groups.

  1. Inconsistency– Every department in an enterprise produces data. But the data is dispersed throughout the applications in a variety of formats. This makes it tough to derive valuable inputs from that data.
  2. Access: Since data is stored in operational silos of the Enterprise. It becomes tough to access and use it for decision-making purposes.

By compiling, standardizing and loading the data, Data Warehouse is able to solve the problem by ensuring access and providing a single version of the truth.

How do they do it?

The implementation partner, in association with the IT team, develops the required software and protocols. These software and protocols transform the data to bring them into a common format. This removes systemic errors and logically relates the information collected from other sources.

This data when finally stored can be used by Business Intelligence systems for analysis and reporting purposes.

An extended example

The Data Warehouse offers a “Single version of Truth”. It provides a great value in having a clean and consolidated data where all the users can look into. But the implementation of system poses several organizational as well as technical challenges. These challenges must be addressed to realize the full potential of a Data Warehouse.

Let’s take an example of a consumer goods company.  The company wants to install a data warehouse to manage their sales data.
The enterprise runs three production sites and sells its products to more than a hundred countries. Area managers and local subsidiaries manage the product sales.
Initially, their data was located in spreadsheets managed by a separate controlling department. There were different formats of sales plans figures.  The analysis was primarily done by using the pivot table. These spreadsheets had to be brought together and synchronized manually through complex queries. This raised widespread redundancy and ambiguous version of sales figures.

Hence, to make sense of that data, the company decided to implement a Data Warehouse.  The main aim was to provide current and consolidated data to local subsidiaries and area managers.
The implementation of data warehouse started with the replacement of spreadsheet-based planning.  It brought sales planning supported by data warehousing. Feeding the data from various source table with automated ETL processes made the procedure easier. This has ended the unmanageable manual data imports.
Now the underlying data can be read directly and updated automatically. The changes in the operational data are reflected periodically. This brings uniform appearance with more granularity than before. It even provides data accessibility to each individual involved in the planning process. It also minimizes the inefficiencies caused by gaps in communication by providing a single version of the company’s sales data.

How can Business Intelligence and data warehouse evolve together?

To survive in the customer-driven age of enterprise, BI is continuously evolving.  The technology is adapting to keep up with the data trends. But somehow it has been observed that data warehousing outmoded the maturity of the technology. This has necessitated deriving a Date Warehousing model with certain features:

1. The model must be agile to solve specific business problems to deliver business value quickly.

  1. Data Warehousing must welcome Next Generation of Data. There have been significant changes in data storage and data mining. Data from the Internet of Things is expected to flourish in the competitive battlefield. Hence the new Data Warehouse must offer powerful ways to achieve real-time data streaming. This step can be helpful to initiate better business intelligence.

Final thoughts

Business Intelligence and Data Warehouse have thrived independently. But together they have come forth with the range of physical experience that was proclaimed to be impossible a few years back. Their combination evolved the business beyond the organizational goal and claimed the two disciplines to be impossible to separate. This makes “the product of these technologies is more instrumental to the company than the sum of their benefits independently”.
