Software architecture and design (x) -- Architecture Technology

Iterative and incremental methods

This is an iterative and incremental method , There are five main steps , Help generate candidate solutions . The candidate solution can be further refined by repeating these steps , Finally, create an architecture design that is most suitable for our application . At the end of the process , We can review and communicate with all interested parties .

This is just a possible way . There are many other more formal ways to define , Review and communicate your architecture .

Identify architectural goals

Determine the architectural goals that form the architecture and design process . Flawless and clear goals emphasize architecture , Solve the right problems in the design , And help determine when the current phase is completed , And prepare to move to the next stage .

This step includes the following activities -

Examples of architectural activities include creating a prototype, For information about Web Order processing for applications UI, Create the feedback of customer order tracking application and design certification, as well as the authorization architecture of the application , To perform safety audits .

Key scenarios

This step focuses on the most important design . A scenario is a broad and covered description of user interaction with the system .

Key scenarios are considered the most important scenarios for application success . It helps make architectural decisions . The goal is to , Achieve a balance between business and system objectives . for example , User authentication is a key scenario , Because they are quality attributes （ Security ） And important functions （ The user logs into the system ） Intersection .

Application Overview

Overview of creating applications , This makes the architecture more touchable , Relate it to the constraints and judgments of the real world . It includes the following activities -

Identify the application type
Identify the application type , Whether it's mobile apps , Rich client &
