A number, statement, image, or video that may represent specific data.
Ex: Business transaction and raw fact & Objective measurements of the characteristics of entitiess
Data
-It refers to a collection of data, such as words, numbers, images or graphics.
- This is a produced data that contains useful context for some users that may need it
Information
In an information system, any input and output that may display in the system must be accurate and understandable on
every end user.
Characteristics of Information
Every information must be up to date based on the requirements—not too early and not too late for the
end user.
Timeliness
A system must have appropriate and relevant information in every module. It must be relevant to
the user who is using it
Appropriateness
Information must be correct or precise. For example, systems performing calculations must produce the
exact values
Accuracy
Not all information must be displayed in the system. It should only contain the minimum detail that is
appropriate to the user
Conciseness
Any information should be understandable. The format and how the information is presented
are important. make it easier for the user to understand
Understandability
Any information must be complete based on the requirements. If an information is incomplete, it
may lead to bad decisions.
Completeness
What are the 6 Characteristics of Information
Timelines
Appropriateness
Accuracy
Conciseness
Understandability
Completeness
This refers to the components that are interrelated, working together with a common goal to accept inputs and
output
System
Component:
is the information or data a user adds in the system
Input
Component:
is the efficiency of data processing. It enables an organization to process millions of data.
Processing
Component
refers to the data or information that has been processed and displayed to the end users.
Output
Component
refers to the comments or suggestions in the system. This is used to improve or make any process
more manageable for end users
Feedback
Component
is about managing the operations in every process of the system.
Control
This is the scope of activities in which it is limited for viewing or accessing any module of a system
Every user of the system has a specific access on each module
System Boundaries
Every system consists of subsystems that have different objectives and interactions based on the given requirements
Subsystems
It refers to the connection of each system or subsystem boundaries and serves as the connection to display the
output from one (1) system to the input of another system.
Subsystem Interface
This refers to the people, organizations, and other systems that give and receive data from the system.
System Environment
Every system always needs feedback to be able to do its job and to process accurately based on the requirements.
System Feedback
It refers to a set of interrelated components that collect any information or data, process, store, and display the
output to support decision-making.
Information Systems
Information Systems in an organization may consist of hardware, software, people, procedures, and
telecommunication
Information Systems in Organization: Organization
Type of Info Sys:
This system is the most widely used information system. The function of this system is to record data
which are collected at the boundaries of organizations.
