Study Notes

Data Processing and File Systems

  • A data processing (DP) specialist was hired to create a computer-based system to track data and produce required reports due to the limitations of manual file systems.
  • Every discipline develops its own terminology to enable clear communication among practitioners.

Basic File Vocabulary

  • Understanding basic file vocabulary is essential to comprehend subsequent discussions in computerized systems.

Problems with File Systems

  • File systems had problems, including having many data files with related and overlapping data with no means of controlling or managing the data consistently across all files.
  • Each file in the system used its own application program to store, retrieve, and modify data.
  • Each file was owned by the individual or department that commissioned its creation, leading to data inconsistencies.

Evolution of File Systems

  • The file system method was an improvement over manual systems but had limitations that became evident over time.
  • Problems with file systems include lengthy development times and limitations in creating information and ensuring data accuracy.

Manual File Systems

  • Manual file systems were paper-and-pencil systems organized to facilitate data use.
  • These systems were limited in handling large data collections and complex reporting requirements.

Computerized File Systems

  • Computerized file systems were developed to overcome the limitations of manual file systems.
  • Generating reports from manual file systems was slow and cumbersome, leading to the adoption of computer technology.
