Study Notes
Introduction to Data Processing
- Data processing involves the manipulation of data to convert it into a more useful form.
Data Processing Cycle
- Consists of five main stages: Input, Processing, Storage, Output, Distribution.
Categories of Data Processing
- Mechanical Data Processing: Combines manual procedures and mechanical devices like typewriters and calculators.
- Electronic Data Processing: Involves interconnected devices such as computers for processing data.
Areas of Data Processing
- Business Data Processing (BDP): Focuses on establishing, retaining, and processing business data to produce useful information.
- Scientific Data Processing (SDP): Involves handling limited volumes of input with complex logical or arithmetic calculations.
Data Processing Operations
- Recording: Transferring data onto documents or forms.
- Verifying: Checking recorded data for accuracy, given that recording is often manual.
- Duplicating: Reproducing data across multiple documents.
- Classifying: Categorizing data into various groups.
- Sorting: Arranging data in a specific order.
- Calculating: Performing arithmetic manipulations on data.
- Summarizing and Reporting: Condensing data and presenting conclusions in a meaningful format.
- Merging: Combining multiple sets of sorted data based on a common key.
- Storing: Keeping similar data in files for future reference.
- Retrieving: Accessing stored data when needed.
- Feedback: Comparing outputs against pre-defined goals to evaluate performance.
Methods of Processing Data
- Batch Processing: Involves collecting data or programs into groups for efficient serial processing.
- Online Processing: Refers to processes controlled directly by the computer's CPU.
- Real-time Processing: Enables immediate data processing and response, impacting the outcomes of activities.
- Distributed Processing: Connects remote terminals to a central computer system, facilitating inquiries and processing jobs.
