System
A transaction processing system (TPS) is an information
system used to support and record transactions such as
paying for products or paying an employee.

Management Information System
A management information system or MIS provides
routine business information to decision makers in a useful
and convenient format.
Concepts > Business Systems > Information Management > Management Information System
Decision Making
Decision making is the key component of the problemsolving process that takes place in three stages:
intelligence, design, and choice.

MIS Reports
MIS reports present useful information for management,
often compiled by querying a database.

Business Intelligence
Business intelligence
(BI) refers to technologies
that are used to gather and
report information that
supports intelligent
business decision making.

Decision Support System
A decision support system (DSS) is an information
system used to support problem-specific decision making.
Concepts > Business Systems > Information Management > Decision Support System
Geographic Information System
A geographic information
system (GIS) captures,
manages, analyzes, and
displays geographically
referenced information, often
utilizing maps with overlaid
data.
Concepts > Business Systems > Information Management > Geographic Information System
Informatics
Informatics applies computer-based information system
technologies to support traditional disciplines such as
science and medicine.

Enterprise Systems
Enterprise systems are
information systems designed to
support the functions of an
enterprise including knowledge
management, content management,
and customer relationship
management, and the integration of
such systems into enterprise
resource planning systems.

Knowledge Management
A knowledge
management (KM)
system assists an
organization in
capturing, storing,
and distributing
knowledge for use
and reuse by the
organization, and
sometimes its
partners and
customers.
Concepts > Business Systems > Enterprise Systems > Knowledge Management
Customer Relationship
Management
Customer relationship
management (CRM) refers
to the use of information
systems to store detailed
information on prospective,
current, and past
customers to improve
customer service and
support targeted marketing.
Concepts > Business Systems > Enterprise Systems > Customer Relationship Management
Enterprise Resource Planning
An enterprise resource planning (ERP) system integrates
all data processing in a corporation (enterprise) into one
unified system that draws from a central database system to
streamline the flow of information throughout an enterprise.

activity of creating new or
modifying existing information
systems.

Systems Development
Tools
Systems development tools are
various types of software that assist
systems analysts in developing
effective and efficient information
systems quickly and properly.
Concepts > Business Systems > Systems Development > Systems Development Tools
Project Management
Project
management is the
process of planning,
monitoring, and
controlling the
sequence of events
and resources
required in a project,
often using software
tools.
Concepts > Business Systems > Systems Development > Project Management
Systems Investigation
Concepts > Business Systems > Systems Development > Systems Investigation
Systems
investigation is the
first stage in the
systems development
life cycle, in which
information systems
are examined to
determine whether
they are meeting the
objectives and
satisfying the goals of
the organization.
Systems Analysis
Systems analysis, the second stage of the systems development
life cycle, attempts to understand how the existing system helps
solve the problem identified in systems investigation and answers
the question: What must the computer system do to solve the
problem?
Concepts > Business Systems > Systems Development > Systems Analysis
Systems Design
Systems design
is the third stage
of the systems
development life
cycle, in which a
system plan is
created to meet
the requirements
defined in the
requirements
analysis.
Concepts > Business Systems > Systems Development > Systems Design
Systems Implementation
Systems implementation
involves carrying out the
system design to make the
new information system a
reality, including hardware
acquisition, software
acquisition or development,
user preparation, hiring and
training of personnel, site
and data preparation,
installation, testing, startup,
and user acceptance.
Concepts > Business Systems > Systems Development > Systems Implementation
Systems Maintenance
Systems
maintenance, the fifth
stage in the systems
development life cycle,
involves checking,
changing, and
enhancing the system
to make it more useful
in achieving user and
organizational goals.
Concepts > Business Systems > Systems Development > Systems Maintenance
System Review
Systems review is the process of analyzing systems to
make sure that they are operating as intended.
