Pro SQL Server Internals 2-Ed. D. Korotkevitch

Pro SQL Server Internals 2-Ed. D. Korotkevitch

The book is logically separated into eight different parts. Even though all of these parts are relatively independent of each other, I would encourage you to start with Part I, “Tables and Indexes,” anyway. This part explains how SQL Server stores and works with data, which is the key point in understanding SQL Server Internals. The other parts of the book rely on this understanding.

Defensive Database Programming with SQL Server. A. Kuznetsov

Вместо 🍻, держите 📚, потому что только среда!

Defensive Database Programming with SQL Server. A. Kuznetsov

This book describes a lot of specific problems, and typical approaches that will lead to more robust code, However, my main goal is more general: it is to demonstrate how to think defensively, and how to proactively identify and eliminate potential vulnerabilities in T-SQL code during development rather than after the event when the problems have already occurred.
The book breaks down into ten chapters, as described below. Eight of these chapters are available in this free eBook version; the final two chapters are included in paid versions only.

PostgreSQL High Availability Cookbook, 2nd Edition. Shaun Thomas

Welcome to the PostgreSQL 9 High Availability Cookbook! As a database engine, PostgreSQL is settling into its place as a reliable bastion of high-transaction rates and very large data installations. DB-Engines recently listed PostgreSQL as the third most popular database software in the world! With such notoriety comes increasing demand for PostgreSQL to act as a critical piece of infrastructure. System outages in these environments can be spectacularly costly and require a higher caliber of management and tooling.
It is the job of a DBA to ensure that the database is always available for application demands and client needs.
