Definition: Detail-Level Architecture Building Block Architecture is a Requirement formulating specific low-level capabilities of a software system. It should provide a structured and consistent approach to develop and maintain the system. This approach is based on breaking the system into smaller and manegable pieces (building blocks) and combined can create a robust and reliable system.
