Early warning signs that an SW-Architecture is in trouble

2010-06-25T11:42:00.001+02:00

The architecture is forced to match the current organization. Top-level architecture components number more than 25. One requirement drives the rest of the design. The architecture depends upon alternatives in the system software. Proprietary components are being used when standard components would do. The component definition comes from the hardware division. There is

Checklist: questions the architect should plan to answer

Observer Pattern

2010-03-05T13:24:00.000+01:00

The observer pattern (a subset of the publish/subscribe pattern) is a software design pattern in which an object, called the subject, maintains a list of its dependants, called observers, and notifies them automatically of any state changes, usually by calling one of their methods. It is mainly used to implement distributed event handling systems. Pic1. Subject-Observer relationship in

Classes vs. Structures in VB.Net

2010-02-01T16:26:00.000+01:00

If there are no requirements for polymorphism and events, then structure type is a good candidate instead of a class. If the container types make use of inheritance and polymorphism, then using class is preferable. A structure can be preferable when: You have a small amount of data and simply want the equivalent of the UDT (user-defined type) of previous versions of Visual Basic You

What Is Analysis and Design? (OOA/D)
