What is a system architecture document?

A system architecture is the conceptual model that defines the structure, behavior, and more views of a system. An architecture description is a formal description and representation of a system, organized in a way that supports reasoning about the structures and behaviors of the system.

What should be in a system architecture document?

Document overview

A general description of the system. The logical architecture of software, the layers and top-level components. The physical architecture of the hardware on which runs the software. The justification of technical choices made.

What is a systems design document?

The System Design Document (SDD) describes how the functional and nonfunctional requirements recorded in the Requirements Document, the preliminary user-oriented functional design recorded in the High Level Technical Design Concept/Alternatives document, and the preliminary data design documented in the Logical Data …

What are the types of system architecture?

Three types of system architectures are identified, integrated, distributed and mixed, (partly integrated and partly distributed). It is shown that the type of interfaces defines the type of architecture. Integrated systems have more interfaces, which furthermore are vaguely defined.
