Information Systems
What Is Accounting?
It is the principal way of organizing and reporting
financial information. It has been called the
“language of business.”
Accounting and information systems comprise the
functional area of business responsible for
providing information to the other areas to enable
them to do their jobs and for reporting the results
to interested parties.
To that end, an accounting system is used to
identify, analyze, measure, record, summarize, and
communicate relevant economic information to
interested parties.
What Is a System?

interacting parts that are coordinated
to achieve one or more common
objectives. Systems must possess

Data Versus Information
Data are raw facts and figures that
are processed to produce
information
Information is data that have
been processed and are meaningful
and useful to users. The terms
“meaningful” and “useful” are
value-laden terms and usually
subsume other qualities such as
timeliness, relevance, reliability,
consistency, comparability, etc.
Functional Steps in Transforming
Data into Information
Data collection - capturing, recording,
validating and editing data for completeness
and accuracy
Data Maintenance/Processing classifying, sorting, calculating data
Data Management - storing, maintaining

Data Control - safeguarding and securing
data and ensuring the accuracy and

What Is an Information
System?
An Information system is a framework in which data
is collected, processed, controlled and managed
through stages in order to provide information to users
It evolves over time and becomes more formalized as
a firm grows and becomes more complex. It can be a
manual or computerized system
Firms depend on information systems in order to
survive and stay competitive
