Introduction
There is no any controversy that the knowledge has become one of most important
features in businesses. A business cannot be developed and cannot even survive
without a proper torrent of knowledge. As well as businesses should manage it well in
order to get the maximum results out of knowledge. As a result of that Knowledge
Management has been identified as one of the fastest growing areas of software
investment. Knowledge in an organization which cannot be disseminated and
communicated with others is considered as useless. When it is shared throughout the
organization it becomes useful to the organization. Knowledge can be disseminated
within an organization via Google sites, social networking, e-mail and etc.
It is said that the major source of wealth is the production and distribution of
information and knowledge since we live in an information economy. It has been
calculated that 55 percent of the United States labor force consists of knowledge and
information workers, and 60 percent of the gross domestic product of the United
States are from the knowledge and information sectors (Laudon, 2011, pp. 417).
Businesses have identified the importance of Knowledge Management. They have
recognized that mostly the value of the firm depends on its ability to gain and manage
knowledge. It has found that a substantial part of a stock market value of a company
is related to firm’s intangible assets, which consists knowledge as an important
component.
When it comes to Knowledge Management, Business Intelligence is playing a vital
role. It says Business Intelligence is used to recognize the capabilities of the firm,
trends, patterns, technologies, future directions in the market and the regulatory
environment in which the organization operates. Same as that it is used to identify the
actions of competitors. Business Intelligence basically supports to the Knowledge
Management function. In fact it is ultimately backing to the decision making function,
which is known as one of the most important function in an organization.

Knowledge Management and Business
Intelligence
Knowledge Management can be elaborated as a systematic process of finding,
selecting, organizing, distilling and presenting information in a way that improves the
organization’s understanding in a specific area of interest. Knowledge Management
comforts an organization to gain the understanding from its own experiences. Certain
activities of Knowledge Management focus on acquiring, storing and utilizing
knowledge in an organization for strategic planning, dynamic learning, problem
solving and decision making.
Knowledge Management technologies support to create, store, retrieve, distribute and
analyze structured and unstructured information. Those Knowledge Management
technologies enhance capabilities of helping to solve current problems, answer
questions and realize new opportunities. There is a vast amount of data in larger firms
including business documents, spreadsheets, databases, e-mails, reports, technical
journals, news and press articles, web documents and contracts. Knowledge
Management technologies are used to search, organize and extract value from these
information sources and focus on development activities.
Business Intelligence focuses on the similar purpose, but from a different point of
view. Business intelligence systems are used for intelligent exploration, integration,
aggregation, and analysis of data originated from various information sources. It
concerns with decision making using data warehousing and On-line analytical
processing techniques. Data warehousing collects relevant data, where it is organized.
Then it can support to decision making objectives. Same as that Business Intelligence
uses data mining and ETL tools for making the decision making function into a more
efficient one.
It is identified data warehouses, ETL tools, OLAP techniques and data mining as most
common components of a Business Intelligence System. At the same time it highly
supports to Business Intelligence System to comfort the decision making process.

Data warehouses
A data warehouse is identified as a database, which stores current and historical data
of the organization. Then it can be analyzed to comfort decision making process. Data
warehouses are filled with data that has been extracted from distributed databases. It
has data which has been originated from various core operational transaction systems
such as manufacturing, sales, customer accounts as well as internet based website
transactions. The data warehouses are filled with information from different
operational databases so that the information can be used all over the organization
with the purpose of decision making and management analysis.
New data warehouses are frequently being filled with business data in order to verify
that the updated data is available for decision making function. As a result of that
decisions which are taken by management are efficient, since those are based on
historical as well as up to minute updated data. In some organizations, they have
created smaller, decentralized warehouses, called data marts rather than a centralized,
enterprise-wide data warehouse which serves the entire entity. Data mart is a sub set
of a data warehouse, where the summarized or most important portion of entity’s data
is placed.
The idea of data warehouses is practically used by Catalina Marketing, which is
recognized as a global marketing firm for major consumer packaged goods,
companies and retailers. It operates an enormous data warehouse, which includes
purchase history of three years. It is considered as the largest loyalty database in the
world. In that case customers’ buying preferences are determined by analyzing the
database of customer purchase histories. When a purchase is done, it is instantly
analyzed with the customer’s buying history in the data warehouse (Laudon, 2011, pp.
222-223).

Same as that the United States Internal Revenue Service (IRS) maintains a data
warehouse, which amalgamates tax payer data, in different systems. It includes
personal information of tax payers as well as tax returns. In that case the warehouse
integrates the data of tax payers from many sources and it makes analyzing part much
easier. It provides a descriptive image of tax payers. Then Internal Revenue Service
(IRS) can identify tax payers, who are most likely to cheat on their income (Laudon,
2011, pp. 223).
ETL tools
ETL tools are responsible for extracting the data from source systems. It transforms
data to a common format from different formats. Then those are loaded into the data
warehouses. Earlier ETL designs and implementation was identified as a supporting
task for the data warehouse. It was not considered as a part of the business
intelligence, but a subset of the data warehousing. But now it has become one of the
most common components of a Business Intelligence System.
ETL solutions have been divided into three stages that find, convert data from various
sources and transfer the results into a data warehouse. The extraction stage involves
with obtaining access to data, which is originated from different sources. The
transformation stage involves with transforming the extracted data. It is considered as
the most complex stage of the ETL process. The load stage involves with loading the
data warehouses with data.
Simply the task of ETL tools is to fulfill the requirements of a business intelligence
system. It extracts data which is in different formats, convert them and load them into
the appropriate data warehouse. The use of ETL tools is identified as the most
efficient way to process data with frequency and timing varying according to the
requirements of businesses. Same as that ETL tools can access to a large volume of
data.
Eventually companies need of reporting data is rapidly increasing. On the other hand
the complexity and volume of the data is rocketing. In practical business world
Walmart Company is handling more than one million transactions in every hour
regarding sales, products, inventory and customers by using ETL tools.

On-Line Analytical Processing (OLAP)
techniques
The utilization of On-Line Analytical Processing is originated with the difficulties
arisen, when data analysis on databases are implemented that are frequently being
updated during transactions via other information systems. Basically On-Line
Analytical Processing is analyzing complex data on a database that are constantly
being updated along with traditional data.
On-Line Analytical Processing can be identified as amelioration of earlier single
dimensional analysis tools that allowed users to analyze data from only one point of
view at a time. It provides a multi-dimensional tool to users. On-Line Analytical
Processing enables users to analyze data from different perspectives and explore it
with the intention of discovering hidden information. Simply On-Line Analytical
Processing backs multi-dimensional data analysis, enabling users to view the same
data in different ways. At the same time On-Line Analytical Processing enables users
to exact online answers even when the data are stored in large databases.
On-Line Analytical Processing allows user access, analysis and modeling of business
problems and sharing of information which is stored in data warehouses. On-Line
Analytical Processing offers techniques for analyzing and drilling data. As well as it
offers tools those are particularly used for generating interactive reports. Basically
On-Line Analytical Processing tools use data mining techniques and statistical
methods to create fast and readable reports that are used for forecasting and strategic
decision making process.
As an example, a leading outsource collection agency for government debts in the
United States has saved $200K in accounting software expenses by using On-Line
Analytical Processing technology. Even it has supported ABC to sell some equity for
$167,000,000 in just nine months.

Data Mining
Data mining is utilized for further discoveries. Data mining techniques are used to
identify relationships and rules. The data mining process includes discovering various
patterns, regularities, rules and generalizations in data resources. Data mining
provides erudition into corporate data that cannot be obtained with On-Line
Analytical Processing by recognizing hidden patterns and relationships in large
databases and rules from them to predict future behavior. The patterns and rules are
used to direct decision making and forecast the consequences of those decisions.
There are several fundamental strategies for data mining. The most frequently used
strategies are classification, prediction, estimation, time series analysis and market
basket analysis. These strategies are aligned with the requirements of an organization
and support to decision making function by breaking through varies regularities,
patterns, rules and generalizations in data resources. As an example, market basket
analysis can be used in a business to model retail sales. Same as that classification can
be used to classify unstructured data. The types of information which can be obtained
from data mining include associations, sequences, classifications, clusters, and
forecasts.
As a practical example for data mining, Harrah’s Entertainment, the second largest
gambling company in industry, uses data mining to recognize its most profitable
customers with the intention of generating more revenue from them. The company
analyzes data about its customers when they play casinos or use hotels. Harrah’s
marketing department uses this information to build a detailed gambling profile. Then
data mining enables the company to identify the favorite gaming experiences of a
regular customer, hid preferences for room accommodations, restaurants and
entertainment. This information conduct management when decisions are made about
how to amplify the most profitable customers, encourage them to spend more and
attract more customers with high revenue generating potential. Harrah’s profits have
been increased with the use of business intelligence and it has become a core piece of
the firm’s business strategy (Laudon, 2011, pp. 226).

Role of components in a Business
Intelligence System
Business Intelligence Systems chiefly extract information with the intention of
supporting managers to solve their structured and unstructured issues. Each
component of a Business Intelligence System can be used to extract information by
acquiring information, searching and gathering information, analyzing information
and delivery of information. Same as that Business Intelligence Systems eliminates
communication barriers that exist at the different organizational levels within the
entity by analyzing historical data. Those analysis enable decision makers to evaluate
former activities and direct future actions.
Basically each component of a Business Intelligence System fulfill some tasks in
order to comfort the decision making process. Simply ETL tools are acquiring and
searching information, data warehouses also acquire information. Both On-Line
Analytical Processing techniques and data mining components are analyzing and
delivering the information.
Acquiring information
It has been more difficult to acquire information, since modern organizations use
more distributed information systems to store their business data. This action is
revealing the business issue. It uses ETL tools in order to direct the processes to find
out the needed information and into which data warehouse that the information should
be stored.
Searching information
The newly loaded data which are in high quality are mined using data mining
techniques and processes after the data are extracted from operational databases. This
action is basically implemented at different quality levels of data. Lower quality data
are searched by using ETL tools. The data, which are in higher quality are being
loaded into a data warehouse.
11
Analyzing information
Managers have to create data models in order to understand and address business
issues. Managers can analyze information from multiple dimensions by data
preprocessing and applying On-Line Analytical Processing and data mining
techniques. As an example, information derived through analysis is directly affected
to decisions related to forecasting sales, promotional campaigns and financial results.
It can be used in fraud detection in some cases.
On-Line Analytical Processing summarizes data and makes predictions based on
historical data. On the other hand data mining reveals hidden patterns in data. Data
mining operates at a detailed level instead of a summary level. In real words, data
mining predicts while On-Line Analytical Processing forecasts. Data mining and On-
Line Analytical Processing can be used to analyze financial data, marketing data,
customer data, production data, wage related data, personal data, logistical data, etc.
Delivery of information
Data mining can be also used to deliver information within an entity. Data mining in a
Business Intelligence System is not only interpreting and evaluating results generated
from the analysis implemented on data stored in data warehouses. Even it can display
reports that enable decision makers to discover various patterns, regularities and
generalizations. On the other hand On-Line Analytical Processing creates quick
reports by utilizing simple data mining techniques by summarizing data. Same as that
data mining provides a descriptive report, while On-Line Analytical Processing
provides a summary of information. Management will get reports that are
inappropriate for the decision making function and reports which are included too
much information without a well defined delivery.
12
Role of Business Intelligence in each
level of management
Simply a Business Intelligence System is collecting, treating and disseminating
information with the intention of reducing the uncertainty of decision making function
in an organization. In this case, organizations need real time data in order to make
decisions. A Business Intelligence System enables users to make decisions by using
real time data by monitoring competition and carrying out continuous analysis of
various data. The Business Intelligence System collects data from various data
sources like operational databases and customer databases, transforms into some
formats. Finally it loads the newly formatted data into data warehouses that are
available to all three level of decision making, operational, tactical and strategic.
Each level of management use different On-Line Analytical Processing techniques
and data mining processes to analyze data and report information that is highly
relevant to them. The information generated from the Business Intelligence System is
being used in all decision making processes. Chiefly decisions at the strategic level
are to set objectives and directed to the tactical level of the organization. At the
tactical level, information is mined from the Business Intelligence System in order to
develop tactics to realize the strategic objectives. On the other hand it pushes
decisions to the operational level of the organization. Different levels of the
organization use information for different purposes. Information provides input to
senior managers at strategic and tactical levels, while information provides input to
lower level managers at the operational level.
13
Operational level decisions
Decisions which are made at the operational level related to the continuous
operations. These decisions are basically based on up to date information. Simply
operational level decisions are considered as decisions, which allow an organization
to run its day today activities. Data that is identified from the operational level by
Business Intelligence System is analyzed and combined with other information in
order to support the strategic planning process. As an example, operational level
decisions provide analysis of products, analysis of employees, analysis of regions, etc.
Tactical level decisions
Decisions which are made at the tactical level are related to planning and it is based
on real time data. It is forecasting to direct the future actions of sales, finance,
marketing, as well as capital management. Tactical decisions are used to comfort
strategic decisions. As an example, it forecasts demand for a given product or service,
makes decisions related to marketing, sales, finance, capital management, etc.
Strategic level decisions
Strategic level decisions set objectives as well as ensure that those are attained.
Business Intelligence Systems provide information in order to support to strategic
decisions which are related to the development of future results based on historical
results, profitability and effectiveness of distribution channels. Simply strategic
decisions use Business Information Systems in order to make forecasts based on
historic data, combine them with current performance and estimate how conditions
will be performed in the future. As an example, decisions are made at the strategic
level by using the Business Intelligence System such as whether to enter into a new
market, whether to launch a new product, etc.
