Study Notes

Data Management

The data life cycle is the sequence of stages that a particular unit of data goes through from its initial generation or capture to its eventual archival and/or deletion at the end of its useful life.

Data Generation or Capture

This is the first stage of the data life cycle where data comes into an organization through data entry, acquisition from an external source, or signal reception, such as transmitted sensor data.
Examples of data generation or capture include interviews, observations, questionnaires, and surveys.

Data Preparation

Data preparation is necessary to process data and make it suitable for processing.
Data entered in data input must be entered correctly using an input device.

Data Processing

Data processing involves transforming data into information based on user requirements.
The way we process data can vary depending on the user's needs.

Information Output

After processing, data becomes information.
This information can be accessed by a user with an output device.

Storage

Storage involves storing information on storage devices.
It is necessary to store information to remove obsolete data.

Data vs. Information

Data refers to the raw facts and figures that are collected.
Information, on the other hand, is the result of organizing, analyzing, and interpreting data to make it meaningful and useful.

Types of Data

Quantitative Data: refers to numerical data that can be used for computation or order processing (e.g., numbers, quantities, measurements).
Qualitative Data: refers to non-numerical data that cannot be measured (e.g., attitudes, opinions, descriptions).

Importance of Data

Data is essential for making informed decisions.
Without data, it is impossible to make informed decisions.

Data Life Cycle

The data life cycle consists of six stages: Generation or Capture, Data Preparation, Data Processing, Information Output, Storage, and Removal of Obsolete Data.
Each stage is crucial in the data life cycle, and all stages are interconnected.
