Schema、Model、Entity的关系请牢记，Schema生成Model，Model创造Entity，Model和Entity都可对数据库操作造成影响，但Model比Entity更具操作性。 Document可等同于Entity，具有属性和操作性 新增 如果是Entity，使用save方法，如果是Model，使用create方法

1. Model.create(doc(s), [callback]): Shortcut for saving one or more documents to the database. MyModel.create(docs) does new MyModel(doc).save() for every doc in docs.

2. Model.count(conditions, [callback]): Counts number of matching documents in a database collection.

3. Model.findOne([conditions], [projection], [options], [callback]): Finds one document.

4. Model.find(conditions, [projection], [options], [callback]): Finds documents

5. Model.remove(conditions, [callback]): Removes documents from the collection.

6. Model.update(conditions, doc, [options], [callback]): Updates documents in the database without returning them.

7. Model#save([options], [options.safe], [options.validateBeforeSave], [fn])

8. Schema#virtual(name, [options]): Creates a virtual type with the given name.

9. VirtualType#set(fn): Defines a setter.

10. Schema#method(method, [fn]): Adds an instance method to documents constructed from Models compiled from this schema.
