While many know of database tuning and work to cover that aspect, professional database developers, managers, and administrators always miss one thing: optimizing their queries to save maximum time and cost and provide the query efficiently. Those who are aware of query optimization often lack the skillset and resources to implement this process at an advanced level efficiently. This book aims to make it easier for them. Here are some ways this book will prove beneficial for readers of all types, e. g. , database administrators, teachers, students, or people genuinely interested in databases: - This book is free of any sort of jargon and complex discussions. The simple language aims to make it accessible to and implementable for people of all backgrounds. - This book uses a very balanced approach. Too much time is not given to concepts that may be irrelevant, nor is anything missed out (purposefully) that may be of substantial importance to the readers. - Simplified code is provided that can be used by the readers as a reference. This approach allows the readers to get onto practical implementation immediately. - This book sticks to the point. That means the readers are likely to get exactly what they are looking for and will not find the book's title misleading by the time they are done reading the book. - This book attempts to cover all the aspects of query optimization. However, since it is not a textbook and just covers advanced optimization techniques, an adequate amount of background knowledge may be expected from the readers. By the end of this book, readers will have a greater understanding of databases and understand all the considerations of efficient use of databases. The contents of this book will equip readers with the capability to practically apply the given concepts for efficient querying. Take your database career to the next level
