Detailed Design of the Transactions and Class Methods

Abstract

This chapter describes how to map a top-level description of a transaction into a detailed description, and then how to “decompose” a detailed description of a transaction into various methods which are then attached to proper classes. Two equivalent techniques for describing methods are provided: pseudo code and message charts. The chapter ends with a review on the products of the design phase, which serve as input to the system construction (programming) phase.
