 - [TodoItem](https://github.com/dexie/Dexie.js/blob/master/samples/dexie-cloud-todo-app/src/db/TodoItem.ts) - the shape of a to-do item, declared as a simple typescript interface.
 - [TodoList](https://github.com/dexie/Dexie.js/blob/master/samples/dexie-cloud-todo-app/src/db/TodoList.ts) - the shape and logic of a to-do list - declared as a class with methods for sharing, deleting etc - operations that involves transactions and logic, perfectly encapsulated in class! Please look at its methods to learn how realms, members, sharing and deletion should be done in order to [preserve consistency](/cloud/docs/consistency) across various offline use cases.
 
-Whether to encapsulate logic in a class as we do with [TodoList](https://github.com/dexie/Dexie.js/blob/master/samples/dexie-cloud-todo-app/src/db/TodoList.ts) is only a question of taste. It could equally well have been a pure interface just like we did with [TodoItem](https://github.com/dexie/Dexie.js/blob/master/samples/dexie-cloud-todo-app/src/db/TodoItem.ts). However, having the consistency logic close to the model is a way to encourage correct usage of the model.
