Question: Define and explain the concepts of a record and a field in a database management system. Answer: A record, also known as a row or tuple, is a collection of related data items representing a single entity in a database. Records consist of a set of fields, with each field containing a data value for a specific attribute of the entity. A table in a relational database consists of multiple records, each representing a unique instance of the entity. On the other hand, a field, also known as a column or attribute, is a specific data item within a record. Fields represent individual attributes of an entity, and each field has a specific data type defining its values. In a relational database, a table consists of multiple fields, allowing for the storage of different attributes of the entity the table represents. Together, fields make up a complete record for each instance of an entity in the table.
