A schema defines the structure, types, and validation of documents. A model is compiled from a schema and provides CRUD methods to interact with documents. The schema is the blueprint; the model is the tool.
Create a new schema with new mongoose.Schema({ field: type }). For example, const userSchema = new mongoose.Schema({ name: { type: String, required: true }, email: { type: String, unique: true }, age: Number }).
Use mongoose.model('ModelName', schema). For example, const User = mongoose.model('User', userSchema). The model name maps to a collection (User becomes 'users'), and you use the model for all CRUD operations.
