different types of system design documents
The System Design Document describes the system requirements, operating environment, system and subsystem architecture, files and database design, input formats, output layouts, human-machine interfaces, detailed design, processing logic, and external interfaces. INTRODUCTION.
Generally, documentation is divided into two main areas. 1  Process Documents guide the development, testing, maintenance and improvement of systems. They are used by managers, engineers, testers, and marketing professionals. 2  User Documents give customers the information they need to use the product.
Supply a high-level context diagram for the system and subsystems, if applicable. Refer to the requirements trace ability matrix (RTM) in the Functional Requirements Document (FRD), to identify the allocation of the functional requirements into this design document.
