Question

What is the difference between architectural design and detail design?

Answer 1

Architectural design and detail design are two fundamental faces of system design. Architecture design is abstract than detail design and it specifies the fundamental structure and patterns of the system under development. Detail design focuses on all of the implementation details necessary to implement the architecture that is specified.
Therefore, the ultimate purpose of Architectural Design and Detail Design is to create a system that fulfills a set of valid requirements. Part of this process involves creation of the interface design which is very important to establish as early as possible. This allows detailed test plans to be completed and for test code implementation to start.
