Database Management System (DBMS) is one of the core subjects in computer science and IT. It focuses on concepts, design, implementation, and management of databases that are used to store, organize, and retrieve data efficiently. Below is a complete syllabus outline, covering all the major topics typically taught in undergraduate and professional courses.

• Relational Algebra (Selection, Projection, Union, Intersection, Join, Cartesian Product, Division)
• Relational Calculus (Tuple & Domain)
• Concept of Views

5. Structured Query Language (SQL)

• Indexing and Views

6. Database Design and Normalization

• Functional Dependencies
• Anomalies in Database (Insertion, Deletion, Update)
• Normal Forms:
  • 1NF, 2NF, 3NF, BCNF
  • Higher Normal Forms (4NF, 5NF)
• Denormalization
• Decomposition and Dependency Preservation

7. Transaction Management

• Transaction Concepts and Properties (ACID)
• States of a Transaction
• Serializability (Conflict & View)
• Schedules (Serial, Non-serial, Cascadeless)
• Concurrency Control Problems (Lost Update, Dirty Read, Unrepeatable Read, Phantom Read)
• Concurrency Control Techniques
  • Lock-based Protocols
  • Time-stamp Ordering
  • Validation Techniques

8. Recovery System

• Types of Failures (Transaction, System, Media)
• Recovery Techniques
  • Immediate & Deferred Update
  • Shadow Paging
  • Checkpoints
• ARIES Algorithm (basic overview)

9. Indexing and Hashing

• Basics of File Organization (Sequential, Heap, Clustered)
