About this document
Understanding Relational Data Models by Coder Coder is a document available to read on EtoBox.
The relational model represents data as a collection of tables, with each row representing a related set of data values describing a real-world entity. Data is stored and logically organized in tables, while physical storage can be independent. Popular relational database systems include DB2, Oracle, SQL Server and Access. Tables have rows and columns, tuples are rows, and relations define the structure with attributes, keys, and referential integrity constraints to link related data.
