Скачать или смотреть SQL Server Internal Series: Complete 2-Hour Deep Dive into SQL Engine Internals for Interview Prep

💡 Welcome to the Ultimate SQL Server Internals Deep Dive!
In this power-packed 2-hour masterclass, we’ll journey deep into the heart of SQL Server internals — uncovering how the SQL Engine truly works under the hood. Whether you're preparing for a SQL Server interview, aiming to strengthen your database fundamentals, or working toward becoming a performance-tuning expert, this session will give you everything you need! 🚀

This isn’t just a quick overview — it’s a complete internal breakdown of how SQL Server stores, retrieves, and processes your data. We’ll explore how queries travel through the Relational Engine and Storage Engine, how memory is allocated, how the optimizer decides the best plan, and how SQL Server manages concurrency, transactions, and buffer pools.

🧠 What You’ll Learn in This Deep Dive

🔍 SQL Server Architecture Overview – Understand all internal layers: Protocol Layer, Relational Engine, and Storage Engine.

⚙️ Relational Engine Internals – Learn how SQL Server parses, optimizes, and executes T-SQL queries efficiently.

📊 Execution Plan Fundamentals – Understand how the Query Optimizer selects the most cost-effective plan.

💾 Storage Engine Mechanics – Dive deep into pages, extents, data files, transaction logs, and allocation maps.

🧩 Buffer Pool and Memory Management – See how SQL Server caches data and reduces disk I/O.

🔐 Transaction Management & Logging – Explore ACID principles, checkpoints, log writes, and recovery internals.

🧭 Locking and Concurrency Control – Learn how SQL Server handles multiple users and transactions simultaneously.

⚡ Performance Tuning Internals – Discover how to interpret DMVs, query stats, and internal wait types.

🧱 Indexing Internals – Clustered vs. Non-Clustered indexes, B-Tree structures, and how they impact query performance.

🧮 Execution Engine Flow – From query parsing to result generation, trace every internal component in action.

🎯 Why You Should Watch This Video

This 2-hour session is designed as a complete refresher and interview preparation tool for:

💼 DBAs who want to understand the internals behind SQL performance and reliability.

🧑‍💻 Developers who want to write optimized queries and understand how SQL Server executes them.

🎓 Students or professionals preparing for SQL Server interviews, especially roles that test deep knowledge of query processing and storage internals.

🧠 Architects & Data Engineers who want to know how SQL Server behaves under heavy workloads.

By the end of this video, you’ll not only understand SQL Server internals but also be able to answer real-world interview questions confidently — like how SQL Server reads data pages, manages buffer cache, or decides which execution plan to use. 🏆
