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.

NoSQL Distilled. P. Sadalage, M. Fowler

😊Держимся, ребят!
NoSQL Distilled. P. Sadalage, M. Fowler
Every project is different, and there’s no way we can write a simple decision tree to choose the right data store. Instead, what we are attempting here is to provide you with enough background on how NoSQL databases work, so that you can make those judgments yourself without having to trawl the whole web. We’ve deliberately made this a small book, so you can get this overview pretty quickly. It won’t answer your questions definitively, but it should narrow down the range of options you have to consider and help you understand what questions you need to ask.
