## Entries

- [Versioning](https://banes-lab.com/records/architecture/versioning.md): A mechanism that labels each release of an interface or schema, so consumers can tell compatible changes from breaking ones.
- [Separation of Concerns](https://banes-lab.com/records/architecture/separation-of-concerns.md): A design rule that parsing, business logic, persistence and presentation each live in their own part of the code.
- [Information Hiding](https://banes-lab.com/records/architecture/information-hiding.md): A design rule that a module exposes an interface and keeps the implementation decisions behind it private.
- [Modularity](https://banes-lab.com/records/architecture/modularity.md): A design rule that a system is divided into cohesive modules with explicit boundaries and few dependencies between them.
- [Package by Feature](https://banes-lab.com/records/architecture/package-by-feature.md): A design rule that code is grouped by the feature it serves, so one change stays inside one package.
