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. The section numbering for the SSDs will match that used in the Tanager Use Case Specification. This will make it easier for the reader to match the SSDs with the Use Cases.

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.

1.3. Diagrams

All diagrams in this document were generated using Gentleware’s Poseidon for UML tool.
