## Entries

- [Interface Segregation Principle (ISP)](https://banes-lab.com/records/architecture/interface-segregation.md): A design rule that a client depends on an interface holding only the methods it uses.
- [Dependency Inversion Principle (DIP)](https://banes-lab.com/records/architecture/dependency-inversion.md): A design rule that high-level policy and low-level detail both depend on an abstraction owned by the policy.
- [Open/Closed Principle (OCP)](https://banes-lab.com/records/architecture/open-closed.md): A design rule that a module gains new behavior by adding code at an extension point, leaving its existing code unchanged.
- [Liskov Substitution Principle (LSP)](https://banes-lab.com/records/architecture/liskov-substitution.md): A design rule that a subtype can replace its base type anywhere, because it keeps the base type's preconditions, postconditions and invariants.
- [Polymorphism](https://banes-lab.com/records/architecture/polymorphism.md): A mechanism that lets one interface have several implementations, with the implementation chosen by the object that receives the call.
