Book synopsis

SQL Server 2025 Engineering

Diagnose Slow Queries, Master Execution Plans, Design Better Indexes, Optimize T-SQL, Resolve Blocking and Deadlocks, and Build Fast, Reliable Databases

SQL Server performance problems rarely have a single cause. Slow queries can result from poor execution plans, inefficient indexes, inaccurate statistics, parameter-sensitive queries, memory-grant issues, blocking, deadlocks, or workloads that exceed system capacity.

SQL Server 2025 Engineering gives you a practical, evidence-driven approach to finding the real cause and fixing it without relying on guesswork or performance myths.

You will learn how to:

• Diagnose slow queries using execution plans, Query Store, DMVs, wait statistics, and Extended Events.

• Design and validate indexes, statistics, and SARGable T-SQL.

• Troubleshoot cardinality-estimation problems, parameter sensitivity, spills, memory grants, and parallelism.

• Resolve blocking, deadlocks, concurrency problems, and tempdb pressure.

• Build reliable performance baselines and measure before-and-after results.

• Create representative load tests and plan CPU, memory, storage, tempdb, and transaction-log capacity.

• Prepare for SQL Server 2025 upgrades while controlling compatibility and regression risks.

• Apply performance fixes safely with deployment, rollback, and monitoring procedures.

At the center of the book is the RetailCore Performance Lab, a self-contained environment where you reproduce realistic SQL Server performance problems, investigate their causes, implement corrections, and validate the results.

You will also learn the TRACE Performance Engineering Method-a repeatable process for triaging problems, recording evidence, analyzing root causes, correcting verified issues, and evaluating the complete workload.

Whether you are a DBA, developer, data engineer, performance engineer, or SQL Server professional, this book will help you move from "SQL Server is slow" to a structured process for finding out why-and proving that your fix worked.
