Sequence Diagram Specification

1. Introduction

1.1. Purpose

This document provides the detailed Sequence Diagrams for the Tanager project. Sequence Diagrams will be generated for all main success scenarios, frequently-used scenarios, and complex scenarios. The section numbering for the Sequence Diagrams will match that used in the Tanager System Sequence Diagram Specification and the Tanager Use Case Specification. This will make it easier for the reader to match the Sequence Diagrams with the SSDs and the Use Cases.

1.2. Scope

This document describes the Sequence Diagrams for the Tanager project.

1.3. Definitions, Acronyms, and Abbreviations

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