An Introduction to Database Systems, Volume II



An Introduction to Database Systems, Volume II By C. J. Date
Publisher: Ad..dis..on We..sl..ey 1985 | 400 Pages | ISBN: 0201144743 | DJVU | 3 MB


As its title indicates, this book is a sequel to my earlier book An Introduction to Database Systems (henceforth referred to simply as Volume I). Its overall objective is to describe a somewhat miscellaneous collection of "further database topics"—topics that, despite their importance, had to be omitted from Volume I for a variety of reasons. One of those reasons was that the topics in question did not fit well into that book's overall structure, which was built around what might be termed a "data models" view of database management (all the chapters of that book were related to a greater or lesser degree to a single underlying theme, the theme of data models, and the book thus possessed a reasonably coherent and self-contained structure). The topics of Volume II, by contrast, are much less closely interconnected (as will be made clear below), and in most cases they have little to do with data models per se. In addition, of course, some of these new topics could not reasonably have been included in Volume I at all when that book was first written (about 1972), because they simply had not reached an adequate level of definition or development at that time. Distributed database and database machines are cases in point.
