3.1C Data Life Cycle Notes
The Data Lifecycle
The data life cycle refers to the stages that data goes through from its creation to its destruction.
The data life cycle has five stages:
Creation
Storage
Usage
Preservation
Destruction
Stage 1: Data creation
The first stage of the data life cycle is the creation of data.
New data may be created through manual data entry or collected automatically through the use of different technologies.
Note
Data creation might happen manually, for example, with an employee of a company inputting needed data into a system.
It might also occur automatically, for example, when an algorithm automatically stores calculations needed for further iterations or runs.
Stage 2: Data Storage
Once the data has been created, it needs to be stored persistently.
All stored data should be kept safe with appropriate security measures.

Introduction to Data Life Cycle
The data life cycle refers to the stages that data goes through from its creation to its destruction. Understanding this cycle is crucial for managing data effectively and ensuring its security throughout its existence.
The data life cycle consists of five stages: Creation, Storage, Usage, Preservation, and Destruction.
Each stage has specific processes and considerations that are essential for proper data management.
DefinitionData Life CycleThe series of stages that data passes through from its initial creation to its final destruction.
AnalogyThink of the data life cycle like the life of a book: it's written (created), stored on a shelf (storage), read and used (usage), preserved in a library (preservation), and eventually recycled or destroyed when it's no longer needed (destruction).
