2. Data Vs information
– Data: refers to raw facts and figures. It is without any
proper meaning.
Data may be collection of words, numbers, graphics or
sounds. data about obtained marks of different
subjects for all students is collected.
– INFORMATION
Processed data is called information. When raw
facts and figures are processed and arranged in some
order then they become information. Information has
proper meanings. Information is useful in decision-
making. E.g. statement of results

4. What is a System?
• A System is set of interrelated components,
working together a to achieve a common
objective or set of objectives e.g. computer
system.
• A systems model consists of six components –
inputs, outputs, controls, processes, feedback,
and boundary.
• Input: refers data or commands that are entered
into the computer system usually via an input
device such as a keyboard, mouse etc

5. Cont…
• Processes: is the stage where the input data is
manipulated in order to produce meaningful
information.
• Output is the stage where the information
obtained via processing is presented to the user
in a suitable format e.g. Printout of student exam
results.
• Controls ensure that input data is valid before its
processed, that file and database data are
protected against unauthorised access and
update

6. Cont…
• boundary is the perimeter or border of the
system – elements, features, options, that will
be included in the system.
• Feedback is where the output from a system is
fed back into the system in order to influence
the input.

7. Information System
• An IS is an arrangement of interdependent human
and machine components that interact to support
the operational, managerial, and decision-making
information needs of the business’s end-users.
• An IS is made up of:-
• Hardware
• Software
• People
• Data
• procedures

8. Types of IS
• Transaction Processing Systems As the name
implies, Transaction Processing Systems are designed
to process routine transactions efficiently and
accurately. A business will have several (sometimes
many) TPS; for example : Billing systems to send
invoices to customers
• management information system ("MIS") is mainly
concerned with internal sources of information. MIS
usually take data from the transaction processing
systems and summarize it into a series of
management reports.

9. Cont…
• Decision-support systems ("DSS") are specifically
designed to help management make decisions in
situations where there is uncertainty about the possible
outcomes of those decisions.
• Executive Support System ("ESS") is designed to help
senior management make strategic decisions. It gathers,
analyses and summarizes the key internal and external
information used in the business.
• Office Automation Systems Office Automation Systems
are systems that try to improve the productivity of
employees who need to process data and information.

10. Characteristics of IS
• Accessible. Accessibility is the main requirement of
information system because all authorized users
have to access the system first to do their works.
• Accurate. Of course, information system must be
accurate in calculating and showing the information
because a business may even get loss if there is any
inaccurate data or calculation.
• Simple. Using information system is intended to
simplify business works.

11. Cont…
• Flexible. It’s essential to have a flexible
information system that can be used by all
divisions in a company to see valuable and
important information.
• Secure. Only authorized users are able to
input and manipulate data so there must be
username and password required for them to
access the information.

12. MANAGERS AS INFORMATION
SYSTEM USERS
• Managers exist at various managerial levels and
within various business areas of the firm
• What level an IS is developed for influences how it
operates (see Figure 1.11)
• The 3 primary management levels are (see Figure
1.12):
1. Strategic planning level
2. Management control level
3. Operational control level

14. What Managers Do
• Managerial Functions (Managers do the following):
– Plan what they are to do
– Organize to meet the plan
– Staff their organization with resources
– Direct them to execute the plan
– Control the resources, keeping them on course
