Chapter 1: Introduction to DBMSThis chapter sets the stage by defining databases and the evolution from file-based systems to database systems. Students are introduced to different types of users, DBMS architecture, and the purpose of database languages.
Chapter 2: ER ModelingThe chapter explores the techniques to visually represent data. Students learn how to draw ER diagrams, understand relationships, and convert these diagrams into relational schemas.
Chapter 3: Relational Algebra and Relational CalculusThis chapter focuses on the mathematical backbone of relational databases. Operations like selection, projection, joins, and set operations are explained with examples.
Chapter 4: Structured Query Language (SQL)This crucial chapter dives deep into the world of SQL. From basic data definition and manipulation to complex joins, subqueries, and aggregate functions, every aspect is demonstrated with syntax, examples, and lab problems.
Chapter 5: Database Design and NormalizationStudents learn about data anomalies, functional dependencies, and the process of normalization (1NF to BCNF). The importance of well-structured database design is emphasized.
Chapter 6: Transaction ManagementThis chapter introduces ACID properties and teaches students how to ensure reliable and consistent data operations using transactions. It includes concurrency problems and their solutions.
Chapter 7: Recovery TechniquesFailures are inevitable. This chapter explains how databases recover from crashes using logs, checkpoints, and shadow paging.
Chapter 8: File Organization and IndexingStudents learn how data is stored and accessed efficiently using indexing techniques. Structures like B-Trees and hashing are explained.
Chapter 9: Distributed and NoSQL DatabasesIn the age of big data and cloud computing, this chapter is a must-read. It introduces MongoDB, CAP theorem, and types of NoSQL databases with examples.
Chapter 10: Database Security and AuthorizationStudents learn about role-based access control, SQL injection prevention, user management, and encryption.
Chapter 11: Advanced DBMS ConceptsThe final chapter offers a bird’s eye view of emerging areas such as data warehousing, cloud DBMS, DBaaS, OLAP, and integrating databases with web applications.
