Adding Aspect-Oriented Programming Features to Visual Basic .NET by Using Multidimensional Separation of Concerns (MDSOC) Approach

摘要

Aspect Oriented Programming (AOP) is a new programming paradigm that enhances current programming methodologies. It introduces higher level of modularity and better handling of software complexity by providing another level of abstraction for Separation of Concerns. Multidimensional Separation of Concerns (MDSOC) is one of the AOP approaches with the strong emphasis on addressing software evolution issues including encapsulation of random and/or even the unanticipated concerns. Visual Basic® is commonly used in various business applications that usually change so fast. It should have a good evolution capability. Now, VB .NET™ is very powerful and its abstraction capability enables MDSOC implementation on it. Hyper-VB tool is created to demonstrate how the AOP addition to VB .NET™ using MDSOC approach enhances software evolution, modularity and reusability. The techniques used are adapted from the ones used by Hyper/J™ system (an AOP implementation using MDSOC for Java™ developed by IBM®) and further improved.
