A Database Management System (DBMS) is a software system that facilitates the creation, management, and manipulation of databases. It provides a systematic and efficient way to store, retrieve, and update data, ensuring data integrity, security, and consistency. A DBMS abstracts the underlying hardware and simplifies database management tasks such as querying, updating, and structuring data.

MODULE	TOPIC COVERED
Database Architecture	Architecture of a DBMS: Levels of abstraction (internal, logical, external), and DBMS components.
Data Models	Types of data models: Hierarchical, network, relational, and object-oriented models.
Relational Model	Introduction to the relational model: tables, relations, keys (primary, foreign), and constraints.
SQL (Structured Query Language)	Introduction to SQL: DDL (Data Definition Language), DML (Data Manipulation Language), DCL (Data Control Language).
Normalization	Concepts of normalization, 1NF, 2NF, 3NF, and Boyce-Codd Normal Form (BCNF), and denormalization.
ER Modeling	Entity-Relationship (ER) model: entities, attributes, relationships, ER diagrams, and mapping ER to tables.
Indexing and Hashing	Types of indexing (single-level, multi-level), B-trees, hashing techniques, and their application in efficient data retrieval.
Transaction Management	Concepts of transactions, ACID properties (Atomicity, Consistency, Isolation, Durability), and transaction logs.
Concurrency Control	Techniques for managing concurrent access to databases, locking mechanisms, and isolation levels.
Database Recovery and Backup	Methods for database recovery, types of backups (full, incremental, differential), and recovery techniques (rollback, rollforward).
Database Security	Security mechanisms: user access control, encryption, authorization, and authentication methods.
