Dec 31, Nigel Stanger rated it it was amazing. This guy really knows how SQL works internally, and the tricks for getting the best performance out of it. I've been teaching database tuning for nearly ten years now, and I learned a lot from this book. That is, Faroult treats the process of query and database design as a battle, where you are fighting off the enemy performance slowdowns to reach your objectives the data you need.
He even uses most of the same chapter titles as the original, and the work is peppered with dozens of pithy summaries of the key points. A warning though: In the introduction, Faroult says that the book is intended for developers with at least five years experience in SQL.
Some of the the topics are definitely not for the faint-hearted, but if you meet the requirements, you'll find it an enlightening experience. Aug 03, Mike rated it it was amazing Shelves: This book may have been named after Sun Tzu's classic on military matters, but in substance it reminded me more of another renowned tome on organized conflict, Clausewitz's On War.
The author clearly has a lot of experience and he brings his considerable understanding to bear on how to best decide on a strategy, and on what tactics to use once a proper course has been set.
It has been said there is no substitute for experience. Even so, it never hurts to draw on the experience of others as one mea This book may have been named after Sun Tzu's classic on military matters, but in substance it reminded me more of another renowned tome on organized conflict, Clausewitz's On War.
Even so, it never hurts to draw on the experience of others as one measures a new terrain. Jul 08, John Chilton rated it did not like it. I think this book is wildly overrated, so much so that I am thinking about giving it another chance sometime despite my deep dislike of it.
I started reading it and I barely got through three chapters before giving up. Paragraph to paragraph there is no narrative, no connection. It is entirely disjointed. There are chapter titles, but they seem to be a gimmick that have very little to do with the content in the chapters. Jul 06, Thomas rated it really liked it Shelves: I got a lot out of the first half or so of this book. It did a great job helping me build a better mental model of how a database and query engine works internally, and what tradeoffs various techniques and design choices might be making.

Capturing backups using SSMS or simple scripts is perfectly fine for one-off backup operations, but any backups that form part of the recovery strategy for any given database must be automated and you'll also want to build in some checks that, for example, alert the responsible DBA immediately if a problem arises.
The focus is on practical solutions for removing root causes of these problems, rather than "papering over the cracks". The booklet takes a practical, and well-informed approach to a subject that is not always easy to explain or understand. A Distribution Statistics object is a sampled map of the distribution of data in a table. Most of the time, this work happens effectively without the database administrator having to be aware of what is going on, but occasionally, if the statistics no longer reflect what is actually in the table, then queries can suddenly run grindingly slow.
At this point, the DBA must intervene to correct the problem. Holger divides his work into two parts. In the first part, he explains what 'statistics' are, why they are there, how they are created, updated and removed. He shows how to inspect them and to maintain them. In the second part, he lists all the problems that are related to these statistics objects, and how to solve them. Why, then, aren't all DBAs using them?
Why do even those that do use the DMVs speak wistfully about "good old sysprocesses"? There seem to be two main factors at work. Firstly, some DBAs are simply unaware of the depth and breadth of the information that is available from the DMvs, or how it might help them troubleshoot common issues.
This book investigates all of the DMVs that are most frequently useful to the DBA in investigating query execution, index usage, session and transaction activity, disk IO, and how SQL Server is using or abusing the operating system. Secondly, the DMVs have a reputation of being difficult to use. In the process of exposing as much useful data as possible, sysprocesses has been de-normalized, and many new views and columns have been added.
This fact, coupled with the initially-baffling choices of what columns will be exposed where, has lead to some DBAs to liken querying DMVs to "collecting mystic spells".
Often, they find that they don't have the knowledge, experience, or critically the time, to perform the correct level of maintenance on their SQL Server databases, much as they might like to. This can mean poor performance and reduced availability.
Regardless of the size of your organization, if your mission critical data becomes unavailable, then business will suffer greatly. He explains how to assess and categorize data elements according to sensitivity, regulate access to the various categories of data using database roles, views and stored procedures, and then how to implement a secure data architecture using features such as cell-level encryption, transparent data encryption, one-way encryption, obfuscation, and more.
The battle to secure personal and business data is a tough one, and the consequences of mishandling sensitive data can be severe. Even more damaging than the fines and lawsuits that can be result from non-compliance with regulations, is the loss of customer confidence that results when these breaches of security occur.
Database Administrators must use every weapon and strategy at his or her disposal in the "war" to protect their sensitive data from would-be hackers, phishers, rumor mongers and identity thieves. Encryption is one of the primary weapons with which this battle can be won.
SQL Server Tacklebox For the day-to-day DBA, there are dangers around every corner; monsters waiting to strike down the unsuspecting database with a resource-hungry query, an inefficient data load, or even outright data corruption.
When the worst happens, and SQL Server is down, or performance is suffering, customers are quick to complain.. During such difficult periods, you, the DBA, are the centre of attention. Suddenly, three or four people crowd your desk, laser beam focused on your every action, fully expecting you to solve the problem quickly.
The success of your career as a DBA depends largely on how well-prepared you are to deal with such situations. Talent can't be taught, but every strategist from Sun Tzu to modern-day generals believed that it can be nurtured through the experience of others. They passed on their experience acquired in the field through basic principles that served as guiding stars amid the sound and fury of battle. This is what Faroult does with SQL.
Like a successful battle plan, good architectural choices are based on contingencies. What if the volume of this or that table increases unexpectedly? What if, following a merger, the number of users doubles? What if you want to keep several years of data online? The Art of SQL is not a cookbook, listing problems and giving recipes. The aim is to get you-and your manager-to raise good questions. Clean Code.
