An RDBMS, or Relational Database Management System, consists of several key components:

1. Database: This is the collection of related data. In an RDBMS, data is stored in database objects called tables. A table is a collection of entries which can be related to each other through common attributes.

2. Table: A table is the most simple form of data storage in an RDBMS. A table is a collection of related data entries and it consists of columns and rows.

3. Field: Each table is broken up into smaller entities called fields. The fields in the CUSTOMERS table consist of ID, NAME, AGE, ADDRESS and SALARY.

4. Record or Row: A record, also called a row, is each individual entry that exists in a table. For example, the following are the records in the CUSTOMERS table.

5. Column: A column is a vertical entity in a table that contains all information associated with a specific field in a table.

6. NULL value: A NULL value in a table is a value in a field that appears to be blank, which means a field with a NULL value is a field with no value.

7. Constraints: Constraints are the rules enforced on the data columns of a table. These are used to limit the type of data that can go into a table.

8. Indexes: Indexes are used to retrieve data from the database very fast. An index is a pointer to data in a table.

9. Views: A view is a virtual table based on the result-set of an SQL statement. A view contains rows and columns, just like a real table.

10. Schema: A schema is a collection of database objects, including tables, views, indexes, and synonyms.

11. Database Engine: This is the underlying software component that a DBMS uses to create, read, update and delete (CRUD) data from a database. Most database management systems include their own application programming interface (API) that allows the user to interact with their underlying engine without going through the user interface of the DBMS.
