Book Description
A poorly performing database application not only costs users time, but also has an impact on other applications running on the same computer or the same network. SQL Tuning provides an essential next step for SQL developers and database administrators who want to extend their SQL tuning expertise and get the most from their database applications.There are two basic issues to focus on when tuning SQL: how to find and interpret the execution plan of an SQL statement and how to change SQL to get a specific alternate execution plan. SQL Tuning provides answers to these questions and addresses a third issue that's even more important: how to find the optimal execution plan for the query to use.Author Dan Tow outlines a timesaving method he's developed for finding the optimum execution plan--rapidly and systematically--regardless of the complexity of the SQL or the database platform being used. You'll learn how to understand and control SQL execution plans and how to diagram SQL queries to deduce the best execution plan for a query. Key chapters in the book include exercises to reinforce the concepts you've learned. SQL Tuning concludes by addressing special concerns and unique solutions to "unsolvable problems."Whether you are a programmer who develops SQL-based applications or a database administrator or other who troubleshoots poorly tuned applications, SQL Tuning will arm you with a reliable and deterministic method for tuning your SQL queries to gain optimal performance.

Book Description
Win the war for talent by building an army of ready-to-deploy candidates An employee leaves and you post the open position. Resumes trickle in. You interview a few candidates. No one fits the bill. The next thing you know, three months have passed and that desk is still empty . . . Nothing drives business success like a staff of talented, productive employees. So why accept a hiring process that fails you time and time again? Well, there’s one person who doesn’t: Scott Wintrip. And in High-Velocity Hiring, he provides the tools and systems for creating a hiring process designed for today’s fast-paced, talent-deficient landscape. Using the proven methods Wintrip has applied at some of today’s more forward-thinking companies, you’ll hire top employees faster—and smarter. High-Velocity Hiring replaces the old, worn-out way of hiring with the simple but revolutionary approach of actively cultivating top talent before positions open. The old way is slow and inefficient. Wintrip’s way is dynamic and proven-effective. You’ll enrich and maintain a flow of high-quality candidates, harness this flow by identifying the most talented people, and channel it into a pool of ready-to-hire prospective employees. More than ever, hiring the best people requires foresight, planning, alertness, and decisive action. With High-Velocity Hiring, you have everything you need to seize the high-ground in the war for talent and maintain it for long-term growth and profitability.
