Database technology and entity-relationship (ER) modeling have meanwhile reached the level of an established technology. This book presents the achievements of research in this field in a comprehensive survey. It deals with the entity-relationship model and its extensions with regard to an integrated development and modeling of database applications and, consequently, the specification of structures, behavior and interaction. Apart from research on the ER model and the syntax, semantics, and pragmatics of database modeling the book also presents techniques for the translation of the ER model into classical database models and languages such as relational, hierarchical, and network models and languages, and also into object-oriented models. The book is of interest for all database theoreticians as well as practitioners who are provided with the relevant foundations of database modeling.

In "The Entity-relationship Model: A Basis for the Enterprise View of Data," Peter P.S. Chen presents the foundational concepts of the Entity-Relationship (ER) model. This seminal work, originally published in 1976, introduces a high-level data model designed to facilitate database design and data management within organizations. Chen's ER model offers a structured approach to representing data entities, attributes, and relationships, providing a clear and intuitive framework for understanding and organizing complex data structures. The book explores the principles behind the ER model, illustrating how it can be used to create a comprehensive enterprise view of data. It emphasizes the importance of effective communication between database designers, users, and managers, and demonstrates how the ER model can serve as a common language for defining data requirements and designing robust database systems. This work remains a crucial resource for anyone involved in database design, data modeling, and information management.

Entity-relationship (E-R) diagrams are time-tested models for database development well-known for their usefulness in mapping out clear database designs. Also commonly known is how difficult it is to master them. With this comprehensive guide, database designers and developers can quickly learn all the ins and outs of E-R diagramming to become expe

An entity-relationship approach to the business, a structured, systematic and intuitive business model of entities, relationships and key data for innovation, entrepreneurship and management. The Business Entity-Relationship Model (ERM) presented in this work enables: - acquire a logical and interrelated view of the key elements of the business and its application in the processes of innovation, entrepreneurship and business management - provide a new definition of the business concept, represent all businesses generically, their specific types and any particular business - redefine innovation more broadly, generate ideas and increase innovation capacity - tackle entrepreneurship with an integrated and interdependent vision of the key elements of the new business - plan, execute and control the business strategy against competitors in a sector of economic activity - identify the origin and understand the apparently complex, heterogeneous and abstract concepts used in business management and generate new key or strategic data in an organized and homogeneous form The new model is based on the Entity-Relationship technique, which allows the representation of the real world by elements called entities and relationships that occur between them. In addition, new concepts called supra-entities, supra-relationships and supra-attributes to cover the diversity of situations and perspectives existing in reality are proposed.

Essential to database design, entity-relationship (ER) diagrams are known for their usefulness in data modeling and mapping out clear database designs. They are also well-known for being difficult to master. With Database Design Using Entity-Relationship Diagrams, Third Edition, database designers, developers, and students preparing to enter the field can quickly learn the ins and outs of data modeling through ER diagramming. Building on the success of the bestselling first and second editions, this accessible text includes a new chapter on the relational model and functional dependencies. It also includes expanded chapters on Enhanced Entity-Relationship (EER) diagrams and reverse mapping. It uses cutting-edge case studies and examples to help readers master database development basics and defines ER and EER diagramming in terms of requirements (end user requests) and specifications (designer feedback to those requests), facilitating agile database development. This book Describes a step-by-step approach for producing an ER diagram and developing a relational database from it Contains exercises, examples, case studies, bibliographies, and summaries in each chapter Details the rules for mapping ER diagrams to relational databases Explains how to reverse engineer a relational database back to an entity-relationship model Includes grammar for the ER diagrams that can be presented back to the user, facilitating agile database development The updated exercises and chapter summaries provide the real-world understanding needed to develop ER and EER diagrams, map them to relational databases, and test the resulting relational database. Complete with a wealth of additional exercises and examples throughout, this edition should be a basic component of any database course. Its comprehensive nature and easy-to-navigate structure make it a resource that students and professionals will turn to throughout their careers.

This monograph is devoted to computational morphology, particularly to the construction of a two-dimensional or a three-dimensional closed object boundary through a set of points in arbitrary position. By applying techniques from computational geometry and CAGD, new results are developed in four stages of the construction process: (a) the gamma-neighborhood graph for describing the structure of a set of points; (b) an algorithm for constructing a polygonal or polyhedral boundary (based on (a)); (c) the flintstone scheme as a hierarchy for polygonal and polyhedral approximation and localization; (d) and a Bezier-triangle based scheme for the construction of a smooth piecewise cubic boundary.

"This text presents a comprehensive introduction to an extended Entity-Relationship model both on a conceptual and on a formal, mathematicallevel. In addition to the primitives given by the data model the text introduces a language for the formulation of constraints in order to restrict database states to consistent ones. The text explains an implementation of the approach chosen in the logic programing language PROLOG and discusses in this context the computational power of the proposedcalculus. The extended Entity-Relationship calculus is used to define the meaning of the relational query language SQL. A nice feature of the approach is that it becomes possible to prove language properties on a sound mathematical basis."--PUBLISHER'S WEBSITE.
