Event Sourcing vs CRUD

Developers should use Event Sourcing when building systems that require strong auditability, temporal querying, or complex business logic with undo/redo capabilities, such as financial applications, e-commerce platforms, or collaborative tools meets developers should learn crud because it underpins nearly all data-driven applications, from simple web forms to complex enterprise systems. Here's our take.

Event Sourcing

Nice Pick

Developers should use Event Sourcing when building systems that require strong auditability, temporal querying, or complex business logic with undo/redo capabilities, such as financial applications, e-commerce platforms, or collaborative tools

Pros

  • +It is particularly valuable in microservices architectures for maintaining consistency across services and enabling event-driven communication, as it decouples state storage from business logic and supports scalability through event replay
  • +Related to: domain-driven-design, cqrs

Cons

  • -Specific tradeoffs depend on your use case

CRUD

Developers should learn CRUD because it underpins nearly all data-driven applications, from simple web forms to complex enterprise systems

Pros

  • +It is essential for building RESTful APIs, where CRUD maps to HTTP methods (POST, GET, PUT/PATCH, DELETE), and for database interactions using SQL or ORM tools
  • +Related to: restful-apis, sql

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Event Sourcing if: You want it is particularly valuable in microservices architectures for maintaining consistency across services and enabling event-driven communication, as it decouples state storage from business logic and supports scalability through event replay and can live with specific tradeoffs depend on your use case.

Use CRUD if: You prioritize it is essential for building restful apis, where crud maps to http methods (post, get, put/patch, delete), and for database interactions using sql or orm tools over what Event Sourcing offers.

The Bottom Line
Event Sourcing wins

Developers should use Event Sourcing when building systems that require strong auditability, temporal querying, or complex business logic with undo/redo capabilities, such as financial applications, e-commerce platforms, or collaborative tools
