Advanced Database Systems
Exam Materials
Course Introduction
Advanced Database Systems delves into the principles and technologies underlying modern database management systems beyond the basics. Topics include query optimization, indexing, transaction management, concurrency control, distributed and parallel databases, and emerging models such as NoSQL and NewSQL systems. The course examines challenges in scalability, consistency, reliability, and performance, and explores advanced applications like data warehousing, data mining, and cloud-based data storage. Students will gain practical experience designing, implementing, and tuning advanced database solutions for complex, real-world data problems.
