Learn to Model Software Architecture using UML in 7 steps

Identify quality attributes from business requirements, including availability, scalability, security, usability, and the need for auditing, and balance them across stakeholders to guide architectural decisions.

Define the system boundary and identify actors and data flows with a context diagram. Illustrate interfaces with the mainframe banking system to clarify audiences and data boundaries.

The context diagram provides a high level view of the system for discussions with CIOs and business users, helping estimate effort and plan resources.

Post your recording and create your own context diagram for the Auto Club taxi service case study, then compare your diagram with peers and discuss approaches in the next lecture.

Explore a hands-on context diagram exercise, review how actors and interfaces refine a system model with customers, payment system, and data for analytics, and discuss ongoing refinement through collaboration.

Learn how container diagrams zoom into software systems, defining containers that host runtime code and data, such as a web application using Java and Spring, and explain their interactions.

Use the container diagram to identify the high-level shape of the software and lay down technology choices, guiding architected decisions for the solution framework.

The container diagram addresses the architecture team and project managers as guardians, guiding technology stacks and enabling appropriate architectural decisions, while the whole team gauges project requirements and provisioning activities.

Map a container diagram in a hands-on exercise, detailing a javascript web stack with dynamic and static content, hybrid mobile apps, a reporting container, database storage, and a payment gateway.

Explore the component diagram to identify system components and how each component serves as a physical model, noting that implementation often equates to a package.

Identify major components and their structure and behavior in a component diagram. Show relationships and information flow among web and mobile UIs, customized services, security, customer service, and banking systems.

Model and discuss a component diagram showing how reporting database, analysis services, security services, and event generators interact with views, customer, admin, and business services.

Identify the main purpose of a sequence diagram in software architecture, guiding design principles, patterns, and implementation, and enabling deep dives into specific use cases.

Sequence diagrams illustrate interactions over time with a time axis that proceeds down the page, with horizontal axes showing roles representing objects and life lines.

Explore sequence diagram modeling from a data analyst perspective, detailing authentication, audit logging, and reporting database usage, with collaborative brainstorming with customers and internal review team to refine the diagram.

Learn when to draw sequence diagrams in the project phase, keep them in sync with code, and use them for onboarding and knowledge transfer, including the Autocad Clive Baxi application.

Verify early in the project that the application meets quality attributes using a deployment diagram, such as availability, by illustrating balancers and clusters.

Identify deployment diagram audiences: architects and their teams ensure quality attributes and scalable requirements; production support seeks deployment norms across cloud, data center, and hybrid nodes; stakeholders refine plumbing diagram.

Explore how a deployment diagram, used early in the project phase, validates quality attributes, requirements, and the architecture's ability to sustain business continuity during outages.

Demonstrates constructing deployment diagrams with a DMZ, firewalls, load balancers, proxies, and clustered web servers and databases, highlighting authenticated communication, backup readiness, and multiple diagrams for clarity.

Explore data model definitions across conceptual, logical, and physical levels, and learn how architects and information architects map relationships, keys, and table structures from a high-level view.

Identify the audiences for a UML data model diagram, including DVRs, information architects, production support, and management, and explain how data structures and relationships support maintenance and future changes.

Use diagramming tools early in the project to validate the data model and reveal data structure and relationships. Display the diagram on the wall to ensure shared understanding, aiding maintenance.

Pause the video to sketch the initial high-level data model for the Autocad self-drive Dexia application and draw your model diagram, then redo to compare with the instructor's approach.
