Database Architecture Quiz

Study Notes

Functions of DBMS

A DBMS (Database Management System) performs several functions, including defining, constructing, and manipulating databases
It also controls access, manages concurrency, and ensures database security and integrity
DBMS provides a way to store, retrieve, and manipulate data in a database

DDL (Data Definition Language)

DDL is used to define the structure and organization of a database
It is used to create, modify, and delete database objects such as tables, indexes, and relationships

Logical Structure of a Database

The logical structure of a database is described by the relational model
This model organizes data into one or more tables with rows and columns
Each table has a unique name and consists of rows (also called tuples) and columns (also called attributes)

DML (Data Manipulation Language)

DML primarily deals with managing data in a database
It includes commands such as SELECT, INSERT, UPDATE, and DELETE
These commands are used to retrieve, add, modify, and delete data in a database

Data Encryption Techniques

Data encryption techniques are used to protect data from unauthorized access
These techniques convert plaintext data into unreadable ciphertext to prevent hackers from accessing sensitive information
The purpose of data encryption is to ensure data confidentiality, integrity, and authenticity
