System Sequence Diagram Specification

1. Introduction

1.1. Purpose

This document provides the System Sequence Diagrams (SSDs) for the Tanager project. SSDs will be generated for all main success scenarios, frequently-used scenarios, and complex scenarios.

1.1. Scope

This document describes the System Sequence Diagrams for the Tanager project.

1.2. Definitions, Acronyms, and Abbreviations

A complete list of definitions, acronyms, and abbreviations can be found in the Tanager Glossary.
