Information Modeling
-
Version
2008
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.
