Study Notes
- The concept of data in computing was introduced in 1948 through the paper "A Mathematical Theory of Communication".
Characteristics of Data
- Data consists of recordable facts obtained through reading, observation, counting, measuring, and weighing.
- Data comes from external and internal sources within an organization.
- Data can be an automatic byproduct of routine operations such as generating an invoice.
- The source of data requires considerable attention, as incorrect data leads to worthless information.
Formats of Data
- Data is stored and processed by computers
- Formats include the following:
- Text: strings of charactersu
- Numbers: numerical values
- Audio: speech and music
- Pictures: monochrome and color images
- Video: sequences of pictures like movies or animations, often with synchronized soundtracks
Types of Data: Qualitative or Categorical Data
- Qualitative or Categorical Data cannot be measured or counted numerically; it is sorted by category
- These data types consist of audio, images, symbols, or text
- Examples: gender, language, holiday destination, opinions, and colors.
Classification of Qualitative Data: Nominal Data
- Nominal data labels variables without order or quantitative value, like hair color.
- One color cannot be compared with another.
- The term "nominal" comes from the Latin word "nomen".
