"Know how to track changes and key events in your SQL Server databases in support of application troubleshooting, regulatory compliance, and governance. This book shows how to use key features in SQL Server ,such as SQL Server Audit and Extended Events, to track schema changes, permission changes, and changes to your data. You'll even learn how to track queries run against specific tables in a database. Not all changes and events can be captured and tracked using SQL Server Audit and Extended Events, and the book goes beyond those features to also show what can be captured using common criteria compliance, change data capture, temporal tables, or querying the SQL Server log."

Troubleshoot slow-performing queries and make them run faster. Database administrators and SQL developers are constantly under pressure to provide more speed. This new edition has been redesigned and rewritten from scratch based on the last 15 years of learning, knowledge, and experience accumulated by the author. The book Includes expanded information on using extended events, automatic execution plan correction, and other advanced features now available in SQL Server. These modern features are covered while still providing the necessary fundamentals to better understand how statistics and indexes affect query performance. The book gives you knowledge and tools to help you identify poorly performing queries and understand the possible causes of that poor performance. The book also provides mechanisms for resolving the issues identified, whether on-premises, in containers, or on cloud platform providers. You'll learn about key fundamentals, such as statistics, data distribution, cardinality, and parameter sniffing. You'll learn to analyze and design your indexes and your queries using best practices that ward off performance problems before they occur. You'll also learn to use important modern features, such as Query Store to manage and control execution plans, the automated performance tuning feature set, and memory-optimized OLTP tables and procedures. You will be able to troubleshoot in a systematic way. Query tuning doesn't have to be difficult. This book helps you to make it much easier. What You Will Learn Use Query Store to understand and easily change query performance Recognize and eliminate bottlenecks leading to slow performance Tune queries whether on-premises, in containers, or on cloud platform providers Implement best practices in T-SQL to minimize performance risk Design in the performance that you need through careful query and index design Understand how built-in, automatic tuning can assist your performance enhancement efforts Protect query performance during upgrades to the newer versions of SQL Server Who This Book Is For Developers and database administrators with responsibility for query performance in SQL Server environments, and anyone responsible for writing or creating T-SQL queries and in need of insight into bottlenecks (including how to identify them, understand them, and eliminate them).

Database Security: Problems and Solutions describes and demonstrates how to resolve database security issues at the design, implementation, and production phases. Database security considers and implements those measures or controls in more specific ways than are generally realized in the broader realm of information security. Database security also involves other confidentiality approaches, such as techniques for account credential management, techniques to manage access to data, as well as techniques to manage the types of access. Database security also considers other, less realized, approaches such as database normalization, referential integrity, transactions, locks, and check constraints. Designed for professionals, workshop settings, and self-learners, the book demonstrates several databases so the reader can follow along in a hands-on approach. Each chapter also has a set of questions and follow up projects to reinforce comprehension of the material. FEATURES:Includes demonstration and solution implementations on the major Database Management Systems (MySQL, Oracle, and Microsoft SQL Server) and computing platforms (Linux/UNIX, MacOS, Windows) to be applicable for nearly every student and professionalEnd of chapter exercises to enhance comprehension of topics

This in-depth look at the encryption tools available in SQL Server shows you how to protect data by encrypting it at rest with Transparent Data Encryption (TDE) and in transit with Transport Level Security (TLS). You will know how to add the highest levels of protection for sensitive data using Always Encrypted to encrypt data also in memory and be protected even from users with the highest levels of access to the database. The book demonstrates actions you can take today to start protecting your data without changing any code in your applications, and the steps you can subsequently take to modify your applications to support implementing a gold standard in data protection. The book highlights work that Microsoft has been doing since 2016 to make encryption more accessible, by making TDE available in the standard edition, and the introduction of Always Encrypted that requires minimal work on your part to implement powerful and effective encryption, protecting your data and meeting regulatory requirements. The book teaches you how to work with the encryption technologies in SQL Server with the express goal of helping you understand those technologies on an intuitive level. You'll come away with a deep level of understanding that allows you to answer questions and speak as an expert. The book's aim is to make you as comfortable in deploying encryption in SQL Server as you would be in driving your car to buy groceries. Those with a data security mindset will appreciate the discussion of how each feature protects you and what it protects you from, as well as how to implement things in the most secure manner. Database administrators will appreciate the high level of detail around managing encryption over time and the effect of encryption on database performance. All readers will appreciate the advice on how to avoid common pitfalls, ensuring that your projects to implement encryption run smoothly. What You Will Learn Architect an effective encryption strategy for new applications Retrofit encryption into your existing applications Encrypt data at rest, in memory, and in transit Manage key and certificate life cycles, including backup and restore Recover encrypted databases in case of server failure Work with encryption in cloud-based scenarios Who This Book Is For Database developers, architects, and administrators who want to work with encryption in SQL Server; those who want to maintain encryption whether data is at rest or being transmitted over the network; and those who wish to encrypt their data even when in the server's own memory. Readers should be familiar with SQL Server, but no existing knowledge of encryption is assumed.
