Tuple in DBMS. A tuple, also known as a record or row, is a basic unit of data in a relational database management system (DBMS). A tuple represents a single instance of a relation, or table, in the database. Each tuple contains a set of values, or attributes, that correspond to the columns, or fields, of the relation.

The schema of a table (=relation schema) is defined by the table name and a fixed number of attributes with fixed data types. A record (=entity) corresponds to a row in the table and consists of the values of each attribute. The original "Databases" courses are now all available on edx.org.

A relational database management system (RDBMS) is an information repository that organizes data into tables consisting of rows (records) and columns (attributes that contain the properties of these records). Each table represents a relation, and the rows (also called tuples) hold individual records within that relation.DBMS offers low security and speed. In contrast, RDBMS has a higher speed and is more secure. DBMSs require less software and hardware. In an RDBMS, hardware and software requirements are comparatively higher.
