  dimensional modeling interview questions: Dimensional Modeling: In a Business Intelligence Environment Chuck Ballard, Daniel M. Farrell, Amit Gupta, Carlos Mazuela, Stanislav Vohnik, IBM Redbooks, 2012-07-31 In this IBM Redbooks publication we describe and demonstrate dimensional data modeling techniques and technology, specifically focused on business intelligence and data warehousing. It is to help the reader understand how to design, maintain, and use a dimensional model for data warehousing that can provide the data access and performance required for business intelligence. Business intelligence is comprised of a data warehousing infrastructure, and a query, analysis, and reporting environment. Here we focus on the data warehousing infrastructure. But only a specific element of it, the data model - which we consider the base building block of the data warehouse. Or, more precisely, the topic of data modeling and its impact on the business and business applications. The objective is not to provide a treatise on dimensional modeling techniques, but to focus at a more practical level. There is technical content for designing and maintaining such an environment, but also business content. For example, we use case studies to demonstrate how dimensional modeling can impact the business intelligence requirements for your business initiatives. In addition, we provide a detailed discussion on the query aspects of BI and data modeling. For example, we discuss query optimization and how you can determine performance of the data model prior to implementation. You need a solid base for your data warehousing infrastructure . . . . a solid data model.
  dimensional modeling interview questions: Mastering Data Modeling John Carlis, 2000-11-10 Data modeling is one of the most critical phases in the database application development process, but also the phase most likely to fail. A master data modeler must come into any organization, understand its data requirements, and skillfully model the data for applications that most effectively serve organizational needs. Mastering Data Modeling is a complete guide to becoming a successful data modeler. Featuring a requirements-driven approach, this book clearly explains fundamental concepts, introduces a user-oriented data modeling notation, and describes a rigorous, step-by-step process for collecting, modeling, and documenting the kinds of data that users need. Assuming no prior knowledge, Mastering Data Modeling sets forth several fundamental problems of data modeling, such as reconciling the software developer's demand for rigor with the users' equally valid need to speak their own (sometimes vague) natural language. In addition, it describes the good habits that help you respond to these fundamental problems. With these good habits in mind, the book describes the Logical Data Structure (LDS) notation and the process of controlled evolution by which you can create low-cost, user-approved data models that resist premature obsolescence. Also included is an encyclopedic analysis of all data shapes that you will encounter. Most notably, the book describes The Flow, a loosely scripted process by which you and the users gradually but continuously improve an LDS until it faithfully represents the information needs. Essential implementation and technology issues are also covered. You will learn about such vital topics as: The fundamental problems of data modeling The good habits that help a data modeler be effective and economical LDS notation, which encourages these good habits How to read an LDS aloud--in declarative English sentences How to write a well-formed (syntactically correct) LDS How to get users to name the parts of an LDS with words from their own business vocabulary How to visualize data for an LDS A catalog of LDS shapes that recur throughout all data models The Flow--the template for your conversations with users How to document an LDS for users, data modelers, and technologists How to map an LDS to a relational schema How LDS differs from other notations and why Story interludes appear throughout the book, illustrating real-world successes of the LDS notation and controlled evolution process. Numerous exercises help you master critical skills. In addition, two detailed, annotated sample conversations with users show you the process of controlled evolution in action.

  dimensional modeling interview questions: Dimensional Models of Personality Disorders Thomas A. Widiger, Paul J. Sirovatka, Darrel A. Regier, Erik Simonsen, 2007-05-03 DSM-IV and ICD-10 both diagnose personality disorders categorically, yet studies indicate that many patients meet criteria for an excessive number of diagnoses, raising the question of whether personality disorders are discrete conditions or rather distinctions along dimensions of general personality functioning. This collection of papers renews long-standing proposals for a dimensional model of personality disorder, describing alternative models, addressing questions about their clinical application and utility, and suggesting that future research seek to integrate such models within a common hierarchical structure. With contributions by preeminent researchers in the field, Dimensional Models of Personality Disorders is drawn from a conference series convened by APA, WHO, and NIH in order to plan for the fifth edition of the DSM. The Nomenclature Work Group concluded that consideration should be given to basing part or all of DSM-V on dimensions rather than categories, and recommended that a dimensional model for personality disorders should serve as a basis for exploring dimensional approaches in other areas. Accordingly, the volume opens with a presentation of 18 proposals for dimensional models and proceeds with provocative contributions on a number of related issues ranging from hard science to clinical practice. Among the topics addressed are Behavioral and molecular genetic research supporting an etiologically informed dimensional classification of personality disorders The as-yet tenuous associations between dimensional trait measures of personality as contained in the models of Cloninger, Depue, and Siever-Davis, and specific neurobiological measures, as examined in neurotransmitter research Potential links between childhood and adolescent temperament and personality dimensions and adult personality psychopathology Studies examining the covariation of personality dimensions across cultures The continuity of Axis I and Axis II disorders and a proposed hierarchical structure of mental disorders that integrates the psychopathology of Axis I disorders with specific personality traits The dual challenges of coverage and cutoffs that must be addressed if dimensional models are to be considered viable alternatives to the existing categorical diagnostic system Although the editors acknowledge that concerns are certain to be raised regarding conversion to a dimensional classification -- such as the disruption to clinical practice by a radical shift in diagnosing personality disorder -- these papers make a strong case for opening the field to alternative ways of enhancing clinical utility and improving the validity of basic classification concepts. Together, they offer stimulating insight into how we approach personality disorders, with the hope of encouraging a new model of diagnosis for DSM-V.
