Recently, a set of new software development techniques - termed Aspect-Oriented Software Development (AOSD) - has become available that aims to support modularisation of systemic properties (also referred to as crosscutting-concerns) and their subsequent composition with other parts of the system. Rashid focuses on the use of Aspect-Oriented Programming (AOP) techniques to modularise otherwise broadly scoped features in database systems like the transaction or the versioning model to improve their customisability, extensibility, and maintainability. His aim is to show how the use of AOP can transform the way we develop, use and maintain database systems. He also discusses how database systems can support AOP by providing means for storage and retrieval of aspects. Aspect-Oriented Databases Systems shows the possible synergy between AOSD and database systems and is of particular interest for researchers, graduate students and software developers in database systems and applications.
