unit record
C2Technical/Historical
Definition
Meaning
A term from early computing referring to a single, complete set of related data fields (e.g., one employee's details on a punch card), treated as a discrete entity for processing.
Historically, it describes a data-processing method where individual records are processed sequentially. In modern contexts, it can metaphorically refer to a fundamental, indivisible piece of information or data in a system.
Linguistics
Semantic Notes
The term is largely historical, rooted in 20th-century tabulating machinery (e.g., IBM unit record equipment). It evokes a pre-database, batch-processing era. It is rarely used in contemporary IT outside historical discussion.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. The term originated in American computing (IBM). British English might historically use 'punched card' system as a near-synonym for the technology.
Connotations
Conveys a sense of legacy systems, obsolescence, and sequential, non-relational data handling in both varieties.
Frequency
Extremely low frequency in both. Slightly more likely to be encountered in American texts due to the term's origin with IBM.

Learning
Memory Aids
Mnemonic
Think of a library's old card catalogue: each **unit** (card) is a **record** for one book. Unit record systems worked the same way with data.
Conceptual Metaphor
DATA IS A PHYSICAL OBJECT (to be filed, sorted, and processed one at a time).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'единица записи' in modern contexts; it's a fixed historical term. 'Запись единицы' or 'учетная единица' are incorrect and misleading.
Common Mistakes
- Using it to refer to modern database records. Confusing it with 'unique record'. Using it outside its historical/technical context.
