Answer 2

A Relational Database Management System(RDBMS) is a set of software for managing data that is organized as a Relational Database. A relational database is a digital database based on the relational model of data. The relational model of data representation was proposed by E. F. Codd in 1970. The relational model organizes data into tables of elements with the same representation of attribute fields called columns. The elements in a table are called rows. Every table should have a column or combination of two or more columns that uniquely identify a single row in the table. This is the table’s Primary Key. Tables are said to be related to other tables when the primary key column(s) of one table is(are) contained as attribute columns in another. This key to another table’s row is known as a Foreign Key. Nearly all RDBMS’s present SQL as their primary or only query language.
