Information modeling is a critical process in content management. This book provides basic concepts of information models and explains how to design database based on data analysis and SQL models. It also provides case studies of database design based on information modeling techniques.
This book provides an introduction to the specification and implementation of organizational information systems. It aims to combine and integrate these traditionally compartmentalized activities. This unity is achieved through the use of a relational specification language Z in conjunction with the relational database language SQL. Both these languages have their roots in predicate logic and set theory. Features of the book include:
An introduction to sets, functions and relations which provide the essential foundations for understanding information systems.
A thorough coverage of SQL.
An introduction to database design through two contrasting graphical notations -- conceptual schema and entity-relationship diagrams.
An introduction to the essential components of the Z notation and to the conventions regarding its use.
A discussion of the relationship that must be established between an information system as implemented and its original specification.
Case studies.
End-of-chapter exercises, many of which are answered thus allowing students to pace themselves through the book.
The book suggests that we should take a knowledge-based approach to the development of information systems, with the knowledge first being represented using Z and then re-stated as application programs that use SQL to process a database. Thus the book will be of interest to computing professionals who work in the areas of systems analysis, database design and application programming. It will also provide an integrated introduction to these topics for students of information systems and computer science.

ECTACO Voice Translator is a fairly large electronic phrase book with more than 3200 phrases in 15 categories. It has a built-in text-to-speech engine (TTS) and a voice recognition system, so you can either view the translation of a selected phrase on the screen, or listen to it, or even get your PDA or handheld computer to recognize sentences spoken in one language and to say them back in another!
To be honest, voice recognition is still more like a toy rather than a serious instrument: this task requires massive computing power which is not yet available in handheld devices. But even now in the relatively quiet environment the accuracy of recognition is around 90-95%!
Attractive, convenient and intuitive interface will allow you to find the needed phrase easily and quickly; with TTS you will be able to learn how to pronounce the phrases you use.
ECTACO Voice Translator is a very useful tool for your trips abroad - its phrase bank is filled with carefully selected most common and widely used expressions. And it is much easier to use than a
dictionary, especially if you just started to study the language.
System requirements:
Processor: Intel ARM-206 SA1110 (available in Compaq iPAQ, HP Jornada 56x, Casio E-200, MobilePro P300, Pocket PC e570, etc.)
