Design patterns and object oriented model of a biometric service system

Continuous changes in the software development community require challenging conventional approaches resulting in techniques that allow for early decisions at the design level. This project is a demonstration of the use of design patterns as a common way to organize objects to make practical design decisions helping to generate flexible, manageable and agile software architectures. Due to the continuity and unpredictability of its requirements, the Biometric Industry is appropriate to illustrate of the use of design patterns and object oriented analysis. First, the conceptual model of an Electronic Fingerprint Service establishes the vocabulary for discussing how a system is constructed. Since good design decisions eventually result in a good design model, this model is used to leverage the object reused when requirements change. The Electronic Biometric Services model demonstrates how by applying design patterns, the system can gain the flexibility and agility required to grow and change according to new requirements.
