A type of database in which records are stored in relational form is called relational database management system.. Relational Data Structure. Relation. Attribute. Domain. Tuple. Degree. Cardinality. Data Models. Record-Based Data Models. In a record-based model, the database consists of a number of fixed-format records possibly of differing types. . Each record type defines a fixed number of fields, each typically of a fixed length. . fully) messing things up.

In the 1970s, Codd laid out a plan for improving programmer productivity and accelerating systems development by improving the management and processing of data. Learning Objectives. In this chapter, you will learn:. That the relational database model offers a logical view of data. About the relational model’s basic component: relations. That relations are logical constructs composed of rows (tuples) and columns (attributes). Serge Abiteboul.
