is a combination of machines, people, and processes that for a set of
inputs produces a defined set of outputs
data processing system
A term commonly used _________ with data or storage (codes) processing system is
information system
synonymously
converting data to another form or Language
Conversion
Ensuring that supplied data is “clean, correct and useful.”
Validation
arranging items in some sequence and/or in different sets.
Sorting
– reducing detail data to its main points
Summarization
combining multiple pieces of data.
Aggregation
the “collection, organization, analysis, interpretation and presentation of data
Analysis
list detail or summary data or computed information
Reporting
refers to the transforming raw data into meaningful output
Data processing
can be done
manually using a pen and paper, mechanically using simple devices such as typewriter or electronically
using modern data processing tools in computers
Data
Stages of Data Processing Cycle

Data Processing Methods
Manual Data Processing
Mechanical Data Processing
Electronic Data Processing
data is processed manually without using any machine or tool to
get required results.
manual data processing
data is processed by using different devices like
typewriters, mechanical printers or other mechanical devices.
mechanical data processing method
s the modern technique to process data. The data is
processed through computer; Data and set of instructions are given to the computer as input and the
computer automatically processes the data according to the given set of instructions.
Electronic Data Processing
This method of processing data is very fast and accurate
Electronic Data Processing
Types Of Data Processing
Batch Processing
Online Processing
Real-Time Processing
Distributed Processing
Multi-Processing
Time sharing
is a method where the information to be organized is sorted into groups to allow
for efficient and sequential processing
Batch Processing
This is a method that utilizes Internet connections and equipment directly attached to a computer.
This allows for the data stored in one place and being used at altogether different place.
Online Processing
This technique has the ability to respond almost immediately to various signals in order to acquire
and process information. These involve high maintenance and upfront cost attributed to very advanced
technology and computing power
Real-Time Processing
This method is commonly utilized by remote workstations connected to one big central workstation
or server
Distributed Processing
This type of processing perhaps the most widely used types of data processing. It is used almost
everywhere and forms the basis of all computing devices relying on processors
Multi-Processing
is term used to explain the sequence of steps or process used to process the raw data and turn it into readable form and generate meaningful information
