Ultimate SQL for Relational Database Design guides readers step by step from understanding why structured data matters to building and querying fully functional relational databases. The book begins with the foundations of data organization and the relational model, establishing how tables, keys, and relationships support accurate and scalable systems. The book then walks through Normalization from Unstructured Data (UNF) to Third Normal Form (3NF), showing how to eliminate redundancy, enforce data integrity, and design databases optimized for performance. You transition into hands-on SQL developmentusing Data Definition Language (DDL) to create and modify schemas, followed by Data Manipulation Language (DML) to retrieve, insert, update, and delete data effectively. The journey concludes with intermediate SQL techniquesincluding joins, grouping, filtering, and built-in functionsbefore integrating all concepts into a comprehensive case study so that the readers can confidently design, implement, and query relational databases from scratch.

Redis is one of the worlds fastest and most versatile data platformsbut most teams use only a fraction of what it can do. Ultimate Redis for High-Performance Applications takes you far beyond basic caching and gives you the practical, production-ready knowledge needed to design, scale, and operate Redis with confidence. Hence, whether you are building microservices, streaming systems, gaming backends, AI pipelines, or large-scale distributed applications, this book shows you exactly how Redis behaves under real workloads. You will explore every essential component, such as data structures, persistence, replication, Sentinel, clustering, Lua scripting, monitoring, performance tuning, and cloud deployment, through clear explanations and hands-on examples that map directly to real-world challenges. You will also learn to diagnose bottlenecks, avoid hidden pitfalls, and build systems that stay fast, stable, and scalable under pressure. Thus, whether you are a developer, DBA, architect, or DevOps engineer, this book equips you with the knowledge to turn Redis into a reliable, mission-critical foundation for high-performance applications.
