Creating Value Under Uncertainty
By Adele Goldberg
|
PDF
|
|
Two disciplines, decision analysis and scenario planning, provide a level of rigor to the task of looking into the future. Both combine information available in the present with explicit assumptions, interpretations, and consequences. Why are these disciplines of interest in software engineering?

The Theory of Classification, Part 4: Object Types and Subtyping
By Anthony J.H. Simons
|
PDF
|
|
The "Theory of Classification" explains the behavior of languages such as Smalltalk, C++, Eiffel and Java in a consistent framework, modeling features such as classes, inheritance, polymorphism, message passing, method combination and templates or generic parameters. This installment focuses on sub-typing.

The Dark Side of Object Learning: Learning Objects
By Mahesh H. Dodani
|
PDF
|
|
The “holy grail” of (object) learning has been to facilitate just-in-time learning of skills that is delivered in a manner that works best for the learner. That is, the right skills at the right time in the right way. The state of the art of learning objects shows that it is, at best, at its infancy, and needs substantial work to make it effective.

On Database Technology for US Homeland Security
By Won Kim
|
PDF
|
|
In the wake of the September 11 terrorist attacks, the US government has initiated a wide set of measures to forestall replay of such attacks. One such measure is to encourage development and adoption of information technology to detect and apprehend suspects and security risks, and to manage emergencies should such an attack elude prevention. One element of information technology that is indispensable, particularly in preventing terrorism, is database technology.

The Single Model Principle
By Richard Paige and Jonathan Ostroff
|
PDF
|
|
There are two approaches to using modeling languages such as UML. One approach is based on a single model with constructions of different views based on this model and with consistency checking (automatic or semi-automatic) among the views. The single-model approach is best at providing seamless and reversible engineering of reliable software.

C# and Java: The Smart Distinctions
By Dominik Gruntz
|
PDF
|
|
This paper does not repeat the presentation and discussion of the new language features of C#, but rather focuses on simple and small distinctions to Java that fix common programming trap doors. Some of them are so subtle that they are only recognized when the language report is carefully read.
