Those who read the SQL Server edition of the books will find plenty of new materials covering new subjects, new features, and enhancements in SQL Server , plus revisions and new insights about the existing subjects. These books focus on practical common problems, discussing several approaches to tackle each.
You will be introduced to many polished techniques that will enhance your toolbox and coding vocabulary, allowing you to provide efficient solutions in a natural manner. At the same time, they teach you how to identify the few scenarios where cursor-based solutions are superior to set-based ones. The second book—T-SQL Programming—focuses on procedural programming and assumes that you read the first book or have sufficient querying background. T-SQL Querying starts with five chapters that lay the foundation of logical and physical query processing required to gain the most from the rest of the chapters in both books.
The first chapter covers logical query processing. It describes in detail the logical phases involved in processing queries, the unique aspects of SQL querying, and the special mind-set you need to adopt to program in a relational, set-oriented environment.
The second chapter covers set theory and predicate logic—the strong mathematical foundations upon which the relational model is built. Understanding these foundations will give you better insights into the model and the language. This chapter was written by Steve Kass, who was also the main technical editor of these books. Steve has a unique combination of strengths in mathematics, computer science, SQL, and English that make him the ideal author for this subject.
The third chapter covers the relational model. Understanding the relational model is essential for good database design and helps in writing good code. The chapter defines relations and tuples and operators of relational algebra. Then it shows the relational model from a different perspective called relational calculus.
This is more of a business-oriented perspective, as the logical model is described in terms of predicates and propositions. Data integrity is crucial for transactional systems; therefore, the chapter spends time discussing all kinds of constraints.
Finally, the chapter introduces normalization—the formal process of improving database design.
This chapter was written by Dejan Sarka. Dejan is one of the people with the deepest understanding of the relational model that I know. The fourth chapter covers query tuning. It introduces a query tuning methodology we developed in our company SolidQ and have been applying in production systems.
The chapter also covers working with indexes and analyzing execution plans.
This chapter provides the important background knowledge required for the rest of the chapters in both books, which as a practice discuss working with indexes and analyzing execution plans. These are important aspects of querying and query tuning. The fifth chapter covers complexity and algorithms and was also written by Steve Kass.
This chapter particularly focuses on some of the algorithms used often by the SQL Server engine. It gives attention to considering worst-case behavior as well as average case complexity. By understanding the complexity of algorithms used by the engine, you can anticipate, for example, how the performance of certain queries will degrade when more data is added to the tables involved. Gaining a better understanding of how the engine processes your queries equips you with better tools to tune them.
The chapters that follow delve into advanced querying and query tuning, addressing both logical and physical aspects of your code. These chapters cover the following subjects: The chapter covering querying partitioned tables was written by Lubor Kollar. Lubor led the development of partitioned tables and indexes when first introduced in the product, and many of the features that we have today are thanks to his efforts.
