Oracle SQL High-Performance Tuning with CDROM ReviewIf the idea of slow database response scares you, this is a good place to start. You hear "tuning a database" a lot, but most of it comes too late. There are some queries that no disks, no CPU, and no amount of memory can speed up. Guy Harrison (well named) is expert on tuning SQL, and knows how to write about it in a way that makes it easy for you to benefit.
Besides giving you lots examples of how SQL and PL/SQL can work well, Guy shows you how to use the tools (explain plan, SQL*Trace, Tkprof) that let you know when you are getting close. Actually, he points out that you need to set performance goals early on, and keep testing to see if you are on track; if you don't do that early, it may be too late when you realize you need help. One of my favorite sections is on tuning joins and sub-queries and the accompanying graph showing 197,664 block gets if you do it wrong (wrong index), and 45 if you do it right (using pl/sql instead of correlated subqueries).
The title of this review aside, Guy has good sections on tuning an instance, looking at instance settings and hardware, that can be helpful if you get the application working well and still have slow response times, but most of the chances to have an application that works are available during planning and development, and this book defintely helps there. If you like working with Oracle, and want to know more, you will benefit from this book.Oracle SQL High-Performance Tuning with CDROM Overview61423-0 The complete developer's guide to optimizing Oracle SQL code. Optimizing SQL code is the #1 factor in improving Oracle database performance. Yet most guides to Oracle tuning virtually ignore SQL. Until now. Oracle SQL High-Performance Tuning zeroes in on SQL, showing how to achieve performance gains of 100% or more in many applications. Expert Oracle developer Guy Harrison presents a detailed overview of SQL processing, and then introduces SQL tuning guidelines that improve virtually any application. Learn how to:*Choose execution plans. *Work with joins. *Search for nulls and ranges. *Trace SQL statement execution. *Build indexes that support efficient queries. *Optimize virtually all type of SQL including: views, hierarchical queries, table scans, GROUP BY, updates, subqueries, distributed SQL, and more.As databases grow, and ad hoc queries to data warehouses increase, optimizing SQL becomes even more critical. Harrison offers practical guidance on using Oracle's parallel query facility for large-volume queries, and shows when to use Oracle's PL/SQL instead of standard SQL.The book is replete with examples, showing poorly tuned SQL, how to fix it-and specific performance measurements collected on a wide range of computer hardware, from high-end UNIX SMP hosts to 486 laptops running Personal Oracle.The CD-ROM contains an extraordinary collection of Oracle SQL tuning tools, including:*A complete freeware Tuning Toolkit for generating SQL execution plans in a Windows environment, and for monitoring server load and efficiency. *Trial versions of the SQLab tuning environment, Precise/SQL tuning tools, and SQL Navigator development environment. *Full-function 90-day trial versions of Personal Oracle for Windows 3.1 and Windows 95.If your Oracle applications must deliver supercharged performance, you can't afford to be without Guy Harrison's Oracle SQL High-Performance Tuning.

Microsoft SQL Server 2008 Management and Administration ReviewProduction database administrators have to know at least a little about a lot of things:
* How to install or upgrade SQL Servers
* How to build clusters
* How to plan for disaster recovery and high availability
* How to do performance tuning
* How to secure and protect databases
The production role revolves around management, not creation. Sure, they do need to know T-SQL and be able to debug problem code, but the majority of their day is making the trains run on time - not designing the seats inside the train cars.
Windows administrators who are forced into the SQL Server DBA role need this same type of information. They get handed a database server to manage, often with a database from a third party vendor like Citrix or Blackberry. They have to manage the server, make sure it performs as needed, and back it up safely - but they'll never touch a line of T-SQL code that runs on the server.
Ross Mistry and Hilary Cotter's book Microsoft SQL Server 2008 Management and Administration is a great companion for production DBAs and accidental DBAs. It covers this wide variety of topics in a good depth, and leaves topics like beginning T-SQL or how to write stored procedures out to other books.Microsoft SQL Server 2008 Management and Administration OverviewIf you need to deploy, manage, or secure Microsoft SQL Server 2008, this is the complete, fast-paced, task-based reference you've been searching for. Authored by a world-class expert on SQL Server in the enterprise, this book goes far beyond the basics, taking on the complex tasks that DBAs need to make the most of Microsoft's flagship database platform. SQL Server MVP, Ross Mistry presents proven techniques for SQL Server 2008 installation, upgrades, backup/restore, data transfer, indexing, high availability, security, and much more. He draws on extensive testing in high-profile production environments to offer step-by-step solutions and powerful tips you won't find anywhere else. Every chapter begins with a section identifying SQL Server 2008's most significant new improvements, and concludes with a convenient summary of best practices. Each chapter also outlines the benefits of leveraging Windows Server 2008.

Understand how to:
Master DBA tips, tricks, and best practices proven in actual enterprise environments

Oracle PL/SQL Programming: Covers Versions Through Oracle Database 11g Release 2 (Animal Guide) ReviewThere are always 2-3 books every developer has in their area of expertise and if you're using PL/SQL, the Feuerstein book is one of them.
I'm not sure how much someone can get out of it if they never did work coding before and you're trying to learn it but I can think of many many times I needed an example for a specific problem and the book had a great example of how to do it.
Also I warn people to be careful because especially for the later chapters, they evolve to the answer to the problem and the cognitive method for this book is to follow along to the end to see how it got there - I think to some of the reviewers this is verbose but this really sinks the PL/SQL concept into your brain effectively and in my experience it's clearly worthwhile. I'm amazed (as always) how clear the evolution is if you take the time to follow it.
I might also add if you're not doing PL/SQL for work but trying to learn it, the evolution might not make sense it's very obvious to me the author has hard core real experience to approach the topics the way he does it.
For people in the field, I'd even say if you're a brand new developer on a job or programmed in something else and are approaching PL/SQL for the first time, the examples are more than clear enough and the opening chapters cover relatively universal and simple concepts so I believe the book is extremely beneficial for beginners as well as very advanced PL/SQL developers.Oracle PL/SQL Programming: Covers Versions Through Oracle Database 11g Release 2 (Animal Guide) Overview
