Study Notes
Introduction to Data Processing
- Data processing involves manipulating data into a more useful form.
- College of Information System, Calayan Educational Foundation, Inc., offers an overview of data processing in Computer Fundamentals (COMP100).
Data Processing Cycle
- Basic Cycle: Input → Processing → Output
- Expanded Cycle: Origination → Input → Processing → Storage → Output → Distribution
Categories of Data Processing
- Mechanical Data Processing: Combines manual procedures with machines (e.g., typewriters, calculators).
- Electronic Data Processing: Involves interconnecting various input, output, and storage devices with computers.
Areas of Data Processing
- Business Data Processing (BDP): Focuses on establishing, retaining, and processing data files to produce useful information.
- Scientific Data Processing (SDP): Deals with limited input volumes and numerous logical or arithmetic calculations.
Data Processing Operations
- Recording: Transferring data onto forms/documents.
- Verifying: Checking recorded data for accuracy.
- Duplicating: Reproducing data on multiple documents.
- Classifying: Separating data into distinct categories.
- Sorting: Arranging data in a specific order.
- Calculating: Performing arithmetic operations on data.
- Summarizing and Reporting: Condensing data and presenting conclusions meaningfully.
- Merging: Combining multiple sorted data sets by a common key.
- Storing: Filing similar data for future reference.
- Retrieving: Accessing stored data when needed.
- Feedback: Comparing outputs to set goals.
Methods of Processing Data
- Batch Processing: Collects data/programs into groups for efficient serial processing.
- Online Processing: Equipment directly controlled by the computer’s CPU.
- Real-time Processing: Provides fast responses to data, impacting outcomes immediately.
- Distributed Processing: Links remote terminals to a central computer for inquiries and processing tasks.
