Database File Structures and Indexing for Computer Science Exams

To excel in competitive computer science exams like GATE, you must have a rock-solid grasp of how databases store, organize, and retrieve data behind the scenes. This course breaks down complex storage concepts into clear, written explanations that help you secure top marks. You will transition from understanding basic storage hardware behaviors to confidently calculating index sizes and query costs. What you will learn: - Explain foundational file organization techniques including sequential, heap, and clustered files; - Calculate index sizes, block factors, and search costs for single-level and multi-level indexes; - Understand the internal mechanics of B-trees and B+ trees, including insertion and deletion algorithms; - Apply static and dynamic hashing methods to optimize database search performance; - Compare data replication strategies and their impact on database consistency and availability. This course begins with essential storage terminology and physical hardware concepts before guiding you step-by-step through indexing math, tree-based data structures, and modern replication principles. This course is designed for computer science students, engineering graduates, and exam candidates who want to master database internals from scratch.
