called a database.

A collection of related fields that represents single entities in computer files is commonly referred to as a "record" or "data record." A record is a structured representation of information that organizes multiple data fields together to form a cohesive unit. This allows for efficient storage, retrieval, and manipulation of data within computer files or databases. Records are typically used to store and manage structured data, such as customer information, employee records, financial transactions, or inventory details. Each field within a record corresponds to a specific attribute or characteristic of the entity being represented, and together they form a complete description of that entity.
