Data Processing Flashcards
This deck covers data processing, data verification , validation and logging
What is Data Processing?
Data processing refers to the manipulation, transformation, and organization of raw data into meaningful information.
What is Batch Data Processing?
collecting a set of data or tasks and processing them all at once
What is Online Data Processing?
Involves immediate processing of data as it is received once computers and peripherals are connected to each other or are “online”
What is Real time Data Processing?

What is Time Sharing Data Processing?
Involves sharing computing resources (such as CPU time and memory) among multiple users or processes simultaneously
What is Data Verification?
Data verification is the checking for mistakes when data is copied from one medium to another.
What is Data Validation?
Data Validation is checking data for errors before it is processed.
Human Readable Document
Can be naturally or easily read by a person. A hard copy of the output being printed i.e forms or reports
Turnaround Documentation
A machine and human readable document that has information printed on it by the computer but has more information added to it by a human. i.e mcq exam sheets
What is data logging?
Data logging is a method of automatic data capture where reading from a sensor is entered at regular intervals.
What are the types of Data Validation?
Range Check
Reasonableness Check
Data type Check
Consistency Check
Presence Check
Format Check
What are the two methods of data verification?
Double-entry
Proofreading
