A database record is a group of data related to a topic that is arranged in a table and can contain numerical and non-numerical information. It is also known as a tuple and is part of a collection of records stored in a table, data set, or data file. Each record has one or more values, and the data it includes is determined by the table. Records are often referred to as rows, and fields are called columns. Although the terms rows and records are interchangeable, most database management systems use rows for queries and error messages.
