An RDBMS, or Relational Database Management System, consists of the following:

a. Collection of Tables: These are objects that store data in an RDBMS. Each table has a unique name and consists of rows and columns.

b. Collection of Records: A record is a row in a table. Each record in a table represents a set of related data. For example, in a table of employees, each record could represent a single employee.

c. Collection of Fields: A field is a column in a table. Each field represents a specific piece of data. For example, in a table of employees, fields could include "First Name", "Last Name", "Email", etc.

d. Collection of Keys: Keys are special fields that help to identify, sort, and relate records in a table. There are several types of keys in an RDBMS, including primary keys, foreign keys, and candidate keys.
