Data Modeling Made Simple will provide the business or IT professional with a practical working knowledge of data modeling concepts and best practices. This book is written in a conversational style that encourages you to read it from start to finish and master these ten objectives: Know when a data model is needed and which type of data model is most effective for each situation Read a data model of any size and complexity with the same confidence as reading a book Build a fully normalized relational data model, as well as an easily navigatable dimensional model Apply techniques to turn a logical data model into an efficient physical design Leverage several templates to make requirements gathering more efficient and accurate Explain all ten categories of the Data Model Scorecard Learn strategies to improve your working relationships with others Appreciate the impact unstructured data has, and will have, on our data modeling deliverables Learn basic UML concepts Put data modeling in context with XML, metadata, and agile development Book Review by Johnny Gay In this book review, I address each section in t

OBJECT-ROLE MODELING WORKBOOK (HALPIN, TERRY)
Object-Role Modeling (ORM) is a fact-based approach to data modeling that expresses the information requirements of any business domain simply in terms of objects that play roles in relationships. All facts of interest are treated as instances of attribute-free structures known as fact types, where the relationship may be unary (e.g. Person smokes), binary (e.g. Person was born on Date), ternary (e.g. Customer bought Product on Date), or longer. Fact types facilitate natural expression, are easy to populate with examples for validation purposes, and have greater semantic stability than attribute-based structures such as those used in Entity Relationship Modeling (ER) or the Unified Modeling Language (UML).All relevant facts, constraints and derivation rules are expressed in controlled natural language sentences that are intelligible to users in the business domain being modelled. This allows ORM data models to be validated by business domain experts who are unfamiliar with ORM?s graphical notation. For the data modeler, ORM?s graphical notation covers a much wider range of constraints than can be expressed i

CONCEPCIÓN Y DISEÑO DE BASES DE DATOS: DEL MODELO E/R AL MODELO RELACIONAL. . DEL MODELO E/R AL MODELO RELACIONAL (DE MIGUEL, A. P)
al Modelo Relacional. La finalidad del libro es proporcionar a los lectores unos conocimientos prácticos de la materia, no exentos, sin embargo, del adecuado rigor teórico. Para ello se presentan de forma clara y precisa los conceptos fundamentales de las bases de datos, ofreciendo un tratamiento sistemático de los tres modelos de datos convencionales más extendidos en el mercado: jerárquico, codasyl y relacional. Asimismo, se explica el modelo E/R extendido, enfatizando la importancia de un modelo conceptual, proporcionando unos principios metodológicos que ayuden al diseñador a realizar un buen diseño conceptual y suministrando también una sólida base teórica, la teoría de normalización al diseño lógico de las bases de datos. Con el libro se incluye un disquete en el que se encuentran programados diversos algoritmos de normalización.

FUNDAMENTOS Y MODELOS BASES DE DATOS/2ªED. (PIATTINI VELTHUIS, MARIO G. / SANCHEZ DE MIGUEL, ADOLFO)
El objetivo fundamental de este libro es el estudio de los conceptos básicos y de los principales modelos que se vienen utilizando en los últimos años en el área de las bases de datos. Repasa en primer lugar los Sistemasde Información y Bases de Datos, los componentes de un Sistema de Gestión de la Base de Datos y los elementos más importantes de un Modelo de Datos con el Modelo Entidad/Interrelación (ME/R), así como el modelo relacional (tanto su estática como dinámica) y los modelos en red y jerárquico. Se dedica también un capítulo completo al lenguaje SQL (sentencias de definición, manipulación y control), así como otro al diseño lógico de bases de datos en el modelo relacional, en el que se resume brevemente la teoría dela normalización. Finalmente presenta el futuro de las bases de datos y, en especial, los Sistemas de Gestión de Bases de Datos, así como los principales aspectos dela seguridad (confidencialidad, disponibilidad e integridad) en esta área.

UML AND DATA MODELING (HAY, DAVID)
Here you will learn how to develop an attractive, easily readable, conceptual, business-oriented entity/relationship model, using a variation on the UML Class Model notation.?This book has two audiences:? Data modelers (both analysts and database designers) who are convinced that UML has nothing to do with them; and UML experts who don?t realize that architectural data modeling really is different from object modeling (and that the differences are important). David Hay?s objective is to finally bring these two groups together in peace. ? Here all modelers will receive guidance on how to produce a high quality (that is, readable) entity/relationship model to describe the data architecture of an organization.? The notation involved happens to be the one for class models in the Unified Modeling Language, even though UML was originally developed to support object-oriented design. Designers have a different view of the world from those who develop business-oriented conceptual data models, which means that to use UML for architectural modeling requires some adjustments. These adjustments are described in this b

THE NIMBLE ELEPHANT (GILES, JOHN)
Leverage data model patterns during agile development to save time and build more robust applications.?Get it done well and get it done fast? are twin, apparently opposing, demands. Data architects are increasingly expected to deliver quality data models in challenging timeframes, and agile developers are increasingly expected to ensure that their solutions can be easily integrated with the data assets of the overall organization. If you need to deliver quality solutions despite exacting schedules, ?The Nimble Elephant? will help by describing proven techniques that leverage the libraries of published data model patterns to rapidly assemble extensible and robust designs. The three sections in the book provide guidelines for applying the lessons to your own situation, so that you can apply the techniques and patterns immediately to your current assignments.The first section, Foundations for Data Agility, addresses some perceived aspects of friction between ?data? and ?agile? practitioners. As a starting point for resolving the differences, pattern levels of granularity are classified, and their interdependenc

UML REQUIREMENTS MODELING FOR BUSINESS ANALYSTS (DAOUST, NORMAN)
This book provides you with a collection of best practices, guidelines, and tips for using the Unified Modeling Language (UML) for business analysis. The contents have been assembled over the years based on experience and documented best practices. Over sixty easy to understand UML diagram examples will help you to apply these ideas immediately. If you use, expect to use, or think you should use the Unified Modeling Language (UML) or use cases in your business analysis activities, this book will help you: communicate more succinctly and effectively with your stakeholders including your software development team, increase the likelihood that your requirements will be reviewed and understood, reduce requirements analysis, documentation, and review time. The first three chapters explain the reasons for utilizing the UML for business analysis, present a brief history of the UML and its diagram categories, and describe a set of general modeling guidelines and tips applicable to all of the UML diagram types. Each of the next thirteen chapters is dedicated to a different UML diagram type: Use Case Diagrams Act
