This document discusses architecture patterns for ASP.Net MVC web applications. It covers topics like software components, domain design, infrastructure, ORM strategies including micro ORMs and full-fledged ORMs. It also discusses repositories, database schema, separating read models from the domain, using commands to isolate business logic in the domain, and managing transactions per request. The presentation demonstrates an app called "Let's Go Out" and summarizes key points like using IoC containers, ORMs, separating read and domain models, implementing commands, and handling transactions.

3. Agenda
• What is architecture?
• Let’s Go Out survey
– Infrastructure
– Domain
– DB access

4. What is architecture?
• Network distribution
• Software components
• Services APIs
• Infrastructure
• Domain Design

5. Here & Now
• ASP.Net MVC Web Application
• Approaches & Patterns
• Components/Infrastructure/Domain

6. App demonstration
• Let’s Go Out
• Scheduling

7. Basics – how to start?
• Configuration
• IoC container
• You don’t have to inject everything

8. DB access
Code DB

9. CRUD Hell
• ADO.Net
• ORM

10. Chose ORM strategy
• Micro ORMs
– CRUD
– SQL brought to the front
• Full-fledged ORMs
– Change tracking
– Unit of Work
– Identity map
– DDD

11. Repositories… just don’t
• CRUD in Repository or FindBy… wrappers
• Used only once
• Save

12. DB schema

13. Read model
• Leave the work to DB
• Don’t be afraid of plain SQL
• Separate entities

14. Command Part
• Insert & Update
• Identity Pattern
• Unit of Work

15. Services
• Unit of Work
• DTOs objects
• Transactions

16. Commands
• Only one controller dependency
• Clean domain API
• Easier controller testing (only binding or
validation)
• Logging in bus

17. Transactions
• Connection closing
• Saving changes/Commiting
• Per request

18. Summary
• IoC containers
• ORMs
• Separating ReadModel from Domain
• Commands
• Transactions
