Geographic Information Systems (GIS) have been experiencing a steady and unprecedented growth in terms of general interest, theory development, and new applications in the last decade or so. GIS is an inter-disciplinary field that brings together many diverse areas such as computer science, geography, cartography, engineering, and urban planning. Database Issues in Geographic Information Systems approaches several important topics in GIS from a database perspective. Database management has a central role to play in most computer-based information systems, and is expected to have an equally important role to play in managing information in GIS as well. Existing database technology, however, focuses on the alphanumeric data that are required in business applications. GIS, like many other application areas, requires the ability to handle spatial as well as alphanumeric data. This requires new innovations in data management, which is the central theme of this monograph. The monograph begins with an overview of different application areas and their data and functional requirements. Next it addresses the following topics in the context of GIS: representation and manipulation of spatial data, data modeling, indexing, and query processing. Future research directions are outlined in each of the above topics. The last chapter discusses issues that are emerging as important areas of technological innovations in GIS. Database Issues in Geographic Information Systems is suitable as a secondary text for a graduate level course on Geographic Information Systems, Database Systems or Cartography, and as a reference for researchers and practitioners in industry.

A. Dogramaci and N.R. Adam Productivity of a firm is influenced both by economic forces which act at the macro level and impose themselves on the individual firm as well as internal factors that result from decisions and processes which take place within the boundaries of the firm. Efforts towards increasing the produc tivity level of firms need to be based on a sound understanding of how the above processes take place. Our objective in this volume is to present some of the recent research work in this field. The volume consists of three parts. In part I, two macro issues are addressed (taxation and inflation) and their relation to produc tivity is analyzed. The second part of the volume focuses on methods for productivity analysis within the firm. Finally, the third part of the book deals with two additional productivity analysis techniques and their applications to public utilities. The objective of the volume is not to present a unified point of view, but rather to cover a sample of different methodologies and perspectives through original, scholarly papers."

1 Ali Dogramaci and Nabil R. Adam 1.1. OVERVIEW With the decline of U.S. productivity growth, interest has surged to under stand the behavior of productivity measures through time, the conceptual foundations of productivity analysis, and the linkage between productivity performance and other major forces in the economy. The purpose of this volume is to present a brief overview of some of the concepts used in aggre gate and industry-level productivity analyses and the results of some of the recent research in this field. The book is divided into three parts. Part I covers some of the methodo logical approaches used in aggregate and industry-level productivity studies. Part II deals with the movement of labor productivity measures through time. The papers in this part of the book study productivity changes as uni variate time series and analyze some of the characteristics of the patterns displayed. The papers in Part III address the issues of measurement of capi tal, the relation of capital formation to productivity growth, and the rela tion of imported intermediate inputs to U.S. productivity performance."

1 Nabil R. Adam and Ali Dogramaci Measuring, analyzing, and improving productivity in a given organization is a complex process that involves the contributions of economists, industrial engineers, operations researchers, management scientists, and lawyers. The objective of this book is to provide the reader with a sample of original papers that relate to these productivity topics at the organizational level. In the book, the word organization refers to business firms and municipal organizations. The hook is divided into three parts: perspectives on productivity mea surement, a range of studies at the micro level, and some productivity issues in public organizations. Part I, which consists of three chapters, deals with productivity measurement. The first two chapters of this part cover a broad framework of measurement concepts and techniques; the last chapter, on the other hand, provides the reader with an example of productivity measurement for a specific industry (in this case, food retail ing). Thus, a spectrum of productivity measurement issues is covered in this part of the book."

The information market place is on the horizon. However, it is unlikely that the basic functions of commerce will change appreciably, even as the coming electronic revolution dramatically changes the forms of commerce. Thus, it is of fundamental importance to carefully consider existing commercial activities in designing and proposing new infrastructures for the future.
This volume presents, in eight chapters contributed by leading experts from industry, academia and government, an unique overview of current research issues and applications in the evolving area of electronic commerce; it is based on a workshop held at the National Institute of Standards and Technology in Gaithersburg, Maryland in December 1994.

This volume is the first book coherently summarizing the current issues in digital libraries research, design and management. It presents, in a homogeneous way, thoroughly revised versions of 15 papers accepted for the First International Workshop on Digital Libraries, DL '94, held at Rutgers University in May 1994; in addition there are two introductory chapters provided by the volume editors, as well as a comprehensive bibliography listing 262 entries.
Besides introductory aspects, the topics addressed are administration and management, information retrieval and hypertext, classification and indexing, and prototypes and applications. The volume is intended for researchers and design professionals in the field, as well as for experts from libraries administration and scientific publishing.

Database management is attracting wide interest in both academic and industrial contexts. New application areas such as CAD/CAM, geographic information systems, and multimedia are emerging. The needs of these application areas are far more complex than those of conventional business applications. The purpose of this book is to bring together a set of current research issues that addresses a broad spectrum of topics related to database systems and applications. The book is divided into four parts: - object-oriented databases, - temporal/historical database systems, - query processing in database systems, - heterogeneity, interoperability, open system architectures, multimedia database systems.
