A specific type of numerical identifier, often assigned sequentially within a limited scope or temporary context, serves to differentiate items or entities for a particular process or duration. For example, temporary identification codes used in a market research survey to ensure anonymity and streamline data collection could be considered within this category. These identifiers are not intended for permanent association but rather for short-term tracking and analysis.
The utility of this classification lies in its capacity to provide unique references without requiring the complexities of permanent identification systems. This is particularly beneficial in scenarios involving sensitive data, pilot programs, or preliminary data analysis where establishing enduring identifiers would be premature or impractical. Historically, systems resembling this concept have been employed in early computing environments with limited memory and processing capabilities, facilitating data management within constraints.
