This book is for all data modelers, data architects, and database designers―be they novices who want to learn what's involved in data modeling, or experienced modelers who want to brush up their skills.
A novice will not only gain an overview of data modeling, they will also learn how to follow the data modeling process, including the activities required for each step. The experienced practitioner will discover (or rediscover) techniques to ensure that data models accurately reflect business requirements. This book describes rigorous yet easily implemented approaches to:
modeling of business information requirements for review by business stakeholders before development of the logical data model
normalizing data, based on simple questions rather than the formal definitions which many modelers find intimidating
naming and defining concepts and attributes
modeling of time-variant data
documenting business rules governing both the real world and data
data modeling in an Agile project
managing data model change in any type of project
transforming a business information model to a logical data model against which developers can code
implementing the logical data model in a traditional relational DBMS, an SQL:2003-compliant DBMS, an object-relational DBMS, or in XML.
Part 1 describes business information models in-depth, including:
the importance of modeling business information requirements before embarking on a logical data model
business concepts (entity classes)
attributes of business concepts
attribute classes as an alternative to DBMS data types
relationships between business concepts
time-variant data
generalization and specialization of business concepts
naming and defining the components of the business information model
business rules governing data, including a distinction between real-world rules and data rules.
Part 2 journeys from requirements to a working data resource, covering:
sourcing data requirements
developing the business information model
communicating it to business stakeholders for review, both as diagrams and verbally
managing data model change
transforming the business information model into a logical data model of stored data for implementation in a relational or object-relational DBMS
attribute value representation and data constraints (important but often overlooked)

Описание: Microsoft PowerPivot es un complemento gratuito para Excel de Microsoft que permite a los usuarios producir nuevos tipos de informes y analisis que simplemente eran imposibles antes, y este libro es el primero en abordar formulas DAX, la capacidad central de PowerPivot, desde la perspectiva de la audiencia de Excel. Escrito por el principal blogger a nivel mundial y practicante de la herramienta, los conceptos y el enfoque del libro se introducen de una manera paso a paso sencilla adaptada al estilo de aprendizaje de los usuarios de Excel en todas partes. Las tecnicas que se presentan permiten a los usuarios producir, en horas o incluso minutos, resultados que anteriormente habrian tenido equipos enteros semanas o meses para producir e incluir lecciones sobre la diferencia entre las columnas y medidas calculadas, como formulas pueden ser reutilizadas a traves de informes de totalmente diferentes formas , como combinar conjuntos disjuntos de datos en informes unificados, como hacer que ciertas columnas en un pivote se comporten como si el pivote estuviese filtrado mientras otras columnas no, y como crear calculos de tiempo inteligentes en las tablas dinamicas como "Ano a Ano" y "Medias Moviles" si utilizan un calendario estandar, fiscal o un calendario personalizado. Las tecnicas de "tipo-patron" y las mejores practicas contenidas en este libro se han desarrollado y perfeccionado a lo largo de dos anos de entrenamiento en sitio con los usuarios de Excel de todo el mundo, y las lecciones clave de los seminarios que cuestan miles de dolares por dia ya estan disponibles dentro de las paginas de esta facil de seguir guia. Microsoft PowerPivot is a free add-on to Excel from Microsoft that allows users to produce new kinds of reports and analyses that were simply impossible before, and this book is the first to tackle DAX formulas, the core capability of PowerPivot, from the perspective of the Excel audience. Written by the worlds foremost PowerPivot blogger and practitioner, the books concepts and approach are introduced in a simple, step-by-step manner tailored to the learning style of Excel users everywhere. The techniques presented allow users to produce, in hours or even minutes, results that formerly would have taken entire teams weeks or months to produce and include lessons on the difference between calculated columns and measures, how formulas can be reused across reports of completely different shapes, how to merge disjointed sets of data into unified reports, how to make certain columns in a pivot behave as if the pivot were filtered while other columns do not, and how to create time-intelligent calculations in pivot tables such as "Year over Year" and "Moving Averages" whether they use a standard, fiscal, or a complete custom calendar. The "pattern-like" techniques and best practices contained in this book have been developed and refined over two years of onsite training with Excel users around the world, and the key lessons from those seminars costing thousands of dollars per day are now available to within the pages of this easy-to-follow guide.
