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.

Family-centered Care for Children Needing Specialized Health and Developmental Services
Author: Terri L. Shelton
Publisher:
ISBN: 9780937821879
Category : Child health services
Languages : en
Pages : 120
Book Description
This monograph articulates eight key elements of a family-centered approach to policy and practice for children needing specialized health and developmental services. An introductory section reviews the development of the first edition of the monograph in 1987 and its widespread dissemination and acceptance since that time. Each of the following eight chapters then addresses one of the following elements: (1) recognition that the family is the constant in the child's life, while the service systems and support personnel within those systems fluctuate; (2) facilitation of family/professional collaboration at all levels of hospital, home, and community care; (3) exchange of complete and unbiased information between families and professionals in a supportive manner; (4) respect for cultural diversity within and across all families including ethnic, racial, spiritual, social, economic, educational, and geographic diversity; (5) recognition of different methods of coping and promotion of programs providing developmental, educational, emotional, environmental, and financial supports to families; (6) encouragement of family-to-family support and networking; (7) provision of hospital, home, and community service and support systems that are flexible, accessible, and comprehensive in meeting family-identified needs; and (8) appreciation of families as families, recognizing their wide range of strengths, concerns, emotions, and aspirations beyond their need for specialized health and developmental services and support. Checklists for evaluating these elements are attached. (Contains 160 references.) (DB)

Book Description
Thirty-five years I've written code, a necromancer weaving spells to bring the dead to life. Hardware and electronics never held any charm for me. I've no love for chips and cables and solder. Give me a keyboard, a screen, and a language, and you have my attention. Thirty-five years produced a lot of work. So I thought, maybe time to talk about some of those projects.
