This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
Book Synopsis A Conceptual Approach to Object-oriented Data Modeling by : Gerald Byron Barnes
Download or read book A Conceptual Approach to Object-oriented Data Modeling written by Gerald Byron Barnes and published by . This book was released on 1994 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Object-oriented data modeling is starting to replace the relational model for many recently emerging database applications. The complex nature of these databases precludes mapping of their data directly into a tabular relational structure. Current object-oriented data modeling lacks the standardization and mathematical soundness of the relational model. This thesis addresses this problem by proposing a conceptual data model called OPERA (Object Paradigm / Entity-Relationship Approach). OPERA incorporates the static features of the Entity-Relationship Model with the dynamic properties of object- orientation. In addition to OPERA, an object-oriented extension to the graphical query language GORDAS (Graph-Oriented Data Selection) is proposed. To demonstrate the effectiveness of the proposed model, we will model a United States combat systems support database, the EWIRDB (Electronic Warfare Integrated Reprogramming Database). We map the EWIRDB from its basic relational format to an object schema and then to an OPERA graph. Finally, this conceptual schema is mapped to a GORDAS schema graph and queries are performed on the database. OPERA is conceptually superior to the ER Model and its object-oriented variant, the Enhanced Entity-Relationship Model (EER) Model. We demonstrate this by representing methods as relationship types, which the ER and EER models are incapable of OPERA also aids in query formulation for visual query languages such as GORDAS by providing a query graph mapping template.
Book Synopsis An Extended Entity-relationship Model by : Martin Gogolla
Download or read book An Extended Entity-relationship Model written by Martin Gogolla and published by Springer. This book was released on 1994 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Book Synopsis Entity-Relationship Versus Object-Oriented Modeling and the Underlying DBMS. by :
Download or read book Entity-Relationship Versus Object-Oriented Modeling and the Underlying DBMS. written by and published by . This book was released on 1992 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the impressive accomplishments in relational database research, greater support is needed for persistence of the new types of data encountered with object-oriented programming. The concept of object-orientation is not new in the realm of programming; however, its utilization in database management systems is still immature. Regardless of this fact, there is an urgency for object-oriented database technology. With this increase in demand for the next generation databases comes the need to examine object-oriented data modeling versus the conventional entity-relationship modeling of relational database design. This thesis objective is to analyze both paradigms to determine if object-oriented modeling can significantly improve Department of Defense systems. After analyzing the entity-relationship paradigm and a representation of object-oriented modeling techniques we see a unifying of conceptual models encompassing both application and database development. Object-orientation's higher level of abstraction enables modeling of all problem domains and provides a common language between developer and client. The critical issue in adoption of the object-oriented paradigm becomes not whether to adopt, but how to adopt object-oriented techniques. The benefits of object-oriented technology close the semantic gap by helping the computer to 'see' things our way.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of the workshops associated with the ER'99 18th International Conference on Conceptual Modeling is to give participants access to high level presentations on specialized, hot, or emerging scientific topics. Three themes have been selected in this respect: — Evolution and Change in Data Management (ECDM'99) dealing with han dling the evolution of data and data structure, — Reverse Engineering in Information Systems (REIS'99) aimed at exploring the issues raised by legacy systems, — The World Wide Web and Conceptual Modehng (WWWCM'99) which ana lyzes the mutual contribution of WWW resources and techniques with con ceptual modeling. ER'99 has been organized so that there is no overlap between conference ses sions and the workshops. Therefore participants can follow both the conference and the workshop presentations they are interested in. I would like to thank the ER'99 program co-chairs, Jacky Akoka and Mokrane Bouzeghoub for having given me the opportunity to organize these workshops. I would also like to thank Stephen Liddle for his valuable help in managing the evaluation procedure for submitted papers and helping to prepare the workshop proceedings for publication. August 1999 Jacques Kouloumdjian Preface for ECDM'99 The first part of this volume contains the proceedings of the First International Workshop on Evolution and Change in Data Management, ECDM'99, which was held in conjunction with the 18th International Conference on Conceptual Modehng (ER'99) in Paris, France, November 15-18, 1999.

This book was released on 1994-07-28 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Fuzzy Database Modeling of Imprecise and Uncertain Engineering Information by : Zongmin Ma
Download or read book Fuzzy Database Modeling of Imprecise and Uncertain Engineering Information written by Zongmin Ma and published by Springer. This book was released on 2008-09-12 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer-based information technologies have been extensively used to help industries manage their processes and information systems hereby - come their nervous center. More specially, databases are designed to s- port the data storage, processing, and retrieval activities related to data management in information systems. Database management systems p- vide efficient task support and database systems are the key to impleme- ing industrial data management. Industrial data management requires da- base technique support. Industrial applications, however, are typically data and knowledge intensive applications and have some unique character- tics that makes their management difficult. Besides, some new techniques such as Web, artificial intelligence, and etc. have been introduced into - dustrial applications. These unique characteristics and usage of new te- nologies have put many potential requirements on industrial data mana- ment, which challenge today’s database systems and promote their evolvement. Viewed from database technology, information modeling in databases can be identified at two levels: (conceptual) data modeling and (logical) database modeling. This results in conceptual (semantic) data model and logical database model. Generally a conceptual data model is designed and then the designed conceptual data model will be transformed into a chosen logical database schema. Database systems based on logical database model are used to build information systems for data mana- ment. Much attention has been directed at conceptual data modeling of - dustrial information systems. Product data models, for example, can be views as a class of semantic data models (i. e.
Book Synopsis Fuzzy Database Modeling with XML by : Zongmin Ma
Download or read book Fuzzy Database Modeling with XML written by Zongmin Ma and published by Springer Science & Business Media. This book was released on 2006-06-15 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuzzy Database Modeling with XML aims to provide a single record of current research and practical applications in the fuzzy databases. This volume is the outgrowth of research the author has conducted in recent years. Fuzzy Database Modeling with XML introduces state-of-the-art information to the database research, while at the same time serving the information technology professional faced with a non-traditional application that defeats conventional approaches. The research on fuzzy conceptual models and fuzzy object-oriented databases is receiving increasing attention, in addition to fuzzy relational database models. With rapid advances in network and internet techniques as well, the databases have been applied under the environment of distributed information systems. It is essential in this case to integrate multiple fuzzy database systems. Since databases are commonly employed to store and manipulate XML data, additional requirements are necessary to model fuzzy information with XML. Secondly, this book maps fuzzy XML model to the fuzzy databases. Very few efforts at investigating these issues have thus far occurred. Fuzzy Database Modeling with XML is designed for a professional audience of researchers and practitioners in industry. This book is also suitable for graduate-level students in computer science.
Book Synopsis Fuzzy Database Modeling by : Adnan Yazici
Download or read book Fuzzy Database Modeling written by Adnan Yazici and published by Physica. This book was released on 2013-06-05 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some recent fuzzy database modeling advances for the non-traditional applications are introduced in this book. The focus is on database models for modeling complex information and uncertainty at the conceptual, logical, physical design levels and from integrity constraints defined on the fuzzy relations. The database models addressed here are; the conceptual data models, including the ExIFO and ExIFO2 data models, the logical database models, including the extended NF2 database model, fuzzy object-oriented database model, and the fuzzy deductive object-oriented database model. Integrity constraints are defined on the fuzzy relations are also addressed. A continuing reason for the limited adoption of fuzzy database systems has been performance. There have been few efforts at defining physical structures that accomodate fuzzy information. A new access structure and data organization for fuzzy information is introduced in this book.
Book Synopsis Behavioral Specifications of Businesses and Systems by : Haim Kilov
Download or read book Behavioral Specifications of Businesses and Systems written by Haim Kilov and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Behavioral Specifications of Businesses and Systems deals with the reading, writing and understanding of specifications. The papers presented in this book describe useful and sometimes elegant concepts, good practices (in programming and in specifications), and solid underlying theory that is of interest and importance to those who deal with increased complexity of business and systems. Most concepts have been successfully used in actual industrial projects, while others are from the forefront of research. Authors include practitioners, business thinkers, academics and applied mathematicians. These seemingly different papers address different aspects of a single problem - taming complexity. Behavioral Specifications of Businesses and Systems emphasizes simplicity and elegance in specifications without concentrating on particular methodologies, languages or tools. It shows how to handle complexity, and, specifically, how to succeed in understanding and specifying businesses and systems based upon precise and abstract concepts. It promotes reuse of such concepts, and of constructs based on them, without taking reuse for granted. Behavioral Specifications of Businesses and Systems is the second volume of papers based on a series of workshops held alongside ACM's annual conference on Object-Oriented Programming Systems Languages and Applications (OOPSLA) and European Conference on Object-Oriented Programming (ECOOP). The first volume, Object-Oriented Behavioral Specifications, edited by Haim Kilov and William Harvey, was published by Kluwer Academic Publishers in 1996.
