When digital information is structured in a table or tables or rows and columns, especially named columns where the name of each column describes what content appears in that column for each row. Rows are described as records, and each record is usually assigned a unique ID. Data in different tables are associated with each other based on data in one or more of the columns, often using primary and foreign keys and accessed by a common language such as Structured Query Language or SQL (SQL Keys).
