Fundamentals of Information Systems contains articles from the 7th International Workshop on Foundations of Models and Languages for Data and Objects (FoMLaDO '98), which was held in Timmel, Germany. These articles capture various aspects of database and information systems theory:

identification as a primitive of database models
deontic action programs
marked nulls in queries
topological canonization in spatial databases
complexity of search queries
complexity of Web queries
attribute grammars for structured document queries
hybrid multi-level concurrency control
efficient navigation in persistent object stores
formal semantics of UML
reengineering of object bases and integrity dependence

.
Fundamentals of Information Systems serves as an excellent reference, providing insight into some of the most challenging research issues in the field.
