Sommario/riassunto

Before SQL programmers could begin working with OLTP (On-Line Transaction Processing) systems, they had to unlearn procedural, record-oriented programming before moving on to SQL's declarative, set-oriented programming. This book covers the next step in your growth. OLAP (On-Line Analytical Processing), Data Warehousing and Analytics involve seeing data in the aggregate and over time, not as single transactions. Once more it is time to unlearn what you were previously taught.  This book is not an in-depth look at particular subjects, but an overview of many subjects that will give the

Sommario/riassunto

The Analytical Methods Committee of the Royal Society of Chemistry has for many years been involved in national and international efforts to establish a comprehensive framework for achieving appropriate quality in chemical measurement.This handbook attempts to select or define robust procedures that ensure the best use of resources and enable laboratories to generate consistent, reliable data. Written in concise, easy-to-read language and illustrated with worked examples, it is a guide to current best practice and establishes a control framework for the development and validation of laboratory

Sommario/riassunto

In the late 1980s, pediatric endocrinologists at the Children's Hospital in Winnipeg began to notice a new cohort appearing in their clinics for young people with diabetes. Through dozens of interviews, Krotz shows the impact of the disease on the lives of individuals and families, especially in communities far removed from the medical personnel and facilities available in the city.
