Database Management Systems

The title "Database Management Systems" presents a comprehensive study of the principles, architecture, and practical applications of database management systems (DBMS). This book explores the fundamental concepts of relational databases, including the purpose and structure of DBMS, data models, and system architecture. It provides in-depth coverage of key topics such as relational algebra, SQL fundamentals, database design, and the ACID properties crucial to maintaining data integrity. Beginning with an introduction to database systems, the book elaborates on relational databases, illustrating the structure of tables, the use of keys (primary, foreign, and candidate keys), and data constraints to maintain accuracy and consistency. It progresses into database design principles, focusing on the Entity-Relationship (ER) model, normalization techniques to reduce redundancy, and functional dependencies to ensure efficient database organization. The book covers advanced topics like transaction management, concurrency control, and database recovery techniques, which are essential in high-availability environments. The architecture of DBMS is discussed in detail, including the roles of query processors, storage managers, and different levels of data abstraction. Special sections on indexing, hashing, RAID, and query optimization techniques provide insights into improving database performance and managing large datasets. In its final sections, the book delves into distributed databases, object-based databases, and XML databases, expanding on the role of DBMS in modern applications across various fields. Practical examples from industries like banking, healthcare, and e-commerce illustrate the relevance of DBMS in real-world scenarios. This book serves as a guide for students, database professionals, and software engineers, offering a robust foundation in the design and management of databases.
