The Art of SQL
The Art of SQL by Stephane Faroult and Peter Robson provides best practices that teach experienced SQL users to focus on strategy rather than details. Faroult’s approach takes a page from Sun Tzu’s classic treatise by viewing database design as a military campaign. You need knowledge, skills and talent. Talent cannot be taught, but all strategists, from Sun Tzu to modern generals, believed that it could be cultivated through the experience of others. They conveyed their field experience through basic SQL concepts that served as guiding stars amid the sound and fury of battle. This is what Faroult does with SQL.
Like a successful battle plan, good architectural choices are based on contingencies. What happens if the volume of this or that table increases unexpectedly? What if, after a merger, the number of users doubles? What if you want to keep years of data online? Faroult’s way of viewing SQL performance may be unconventional and unique, but he is extremely serious about writing good SQL and using it. The art of SQL is not a cookbook, it lists problems and offers recipes. The goal is for you and your manager to ask good questions.
Avoiding the Pitfalls of Database Programming (Pragmatic Programmers) by Bill Karwin it’s a collection of anti-patterns, the most common mistakes that he identified in those thousands of help requests. Most developers are not SQL experts and most of the SQL used is inefficient, difficult to maintain, and sometimes just plain wrong. This book shows you all the common mistakes and then guides you through the best solutions. Plus, it shows him what’s behind these fixes, so he’ll learn a lot about relational databases along the way.
Each chapter in this book helps you identify, explain, and correct a unique and dangerous anti-pattern. The four parts of the book bring together anti-models in terms of logical database design, physical database design, querying, and application development. Most likely, your application’s database layer already contains issues like Index Shotgun, Keyless Entry, Fear of the Unknown, and Spaghetti Query. This book will help you and your team find them. Best of all, it will also show you how to fix them and how to avoid these and other problems in the future.
SQL anti-patterns give you a rare insight into an SQL expert’s playbook. Now you can eliminate these common errors from the database once and for all. No matter what platform or programming language you use, whether you are a junior programmer, experienced programmers or a PhD student, SQL Antipatterns will show you how to design and build databases, how to write better database queries, and how to integrate SQL programming into your application. . as an expert. You will also learn the latest and greatest technologies for full-text search, how to design code that is resistant to SQL injection attacks, and other techniques for success.
