Introduction1.1 Purpose and objectivesOverall goals and software objectives are described.1.2 ReadersBrief describe the readers who are concerned about the document.1.3 Overview of the projectBriefly introduce the project information.1.4 Overview of the documentBriefly describe the structure and content of the document. 1.5 DefinitionsDefine the important terms and concepts in the document. 1.6 ReferencesList important references cited in the document.2. Restrictions, imitations, and constraintsDescribe the design constraints of the software such as hardware platform, OS, programming language, development tools, capability, performance, flexibility, etc.3. Software architecture design Describe the architecture design of the software and their models with hierarchy diagram, HIPO diagram, etc. Note: The description of software architecture design should be correct, complete, accurate, clear, consistent, and traceable.3.1 Architecture diagramA pictorial representation of the architecture is presented.3.2 AlternativesA discussion of other architectural styles considered is presented. Reasons for the selection of the style presented in Section3.1.1 are provided.4. Component design For each component in software architecture, describe its design (e.g., internal data structure and algorithm) with flowchart or PDL, etc. Note: The description of software component design should be correct, accurate, clear, consistent, and complete.4.1 Description for component nA detailed description of each software component contained within the architecture is presented. Section 4.1 is repeated for each of n components.4.1.1 Processing narrative (PSPEC) for component nA processing narrative for component n is presented.4.1.2 Component n interface description.A detailed description of the input and output interfaces for the component is presented.4.1.3 Component n processing detailA detailed algorithmic description for each component is presented. Section 4.1.3 is repeated for each of n components.5. Data Design A description of all data structures including internal, global, and temporary data structures.5.1 Global data structureData structured that are available to major portions of the architecture are described.5.2 Data file Data files designs are described.5.3 Database Database(s) created as part of the application is (are) described.5.4 Other data Other data design is (are) described such as network message, protocol, etc.6. Interface DesignDescribe the interface design of the software such as human computer interface, interface to other systems, etc. 6.1 External machine interfacesInterfaces to other machines (computers or devices) are described.6.2 External system interfacesInterfaces to other systems, products, or networks are described.6.3 Human computer interaction interfaceAn overview of any human interfaces to be designed for the software is presented. 7. Appendix Presents information that supplements the design specification.7.1 Requirements traceability matri
