A good architecture provides a strong base to application. I divide whole project in independent and fully functional tiers and layers such as GUI, Business Logic and Repository (DAL & Database), any change in any layer does not affect others, for example change in Business Logic or database will not affect GUI and likewise. To take full advantages of a good architecture I build my own DTO (Data Transfer Objects), BO (Business Objects) and Foundation. This architecture enables me to make any change, bugs fixing, enhancement, parallel development and TDD/ Test Automation quick, simple, easy and effective. I prefer to use Provider Model (Interfaces/Factory Method/Extensibility) if application is extendable and dynamic in nature. My objectives are very clear: client satisfaction at best level, excellent feedback, learning, earning and a good everlasting business relationship.
