Code

Mongoose

Schema、Model、Entity的关系 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。

• Schema

  一种以文件形式存储的数据库模型骨架，不具备数据库的操作能力

  • Types
    String, Number, Boolean/Bool, Array, Buffer, Date, ObjectID/Oid, Mixed

  • Sample
    

     var terminalSchema = new mongoose.Schema({
     	mac : String,
     	id : String,
     	direct : String,
     	version : String,
     	createDate : { type : Date, default : Date.now}
     });
    

• Model

  由Schema发布生成的模型，具有抽象属性和行为的数据库操作对

   var terminalModel = mongoose.model('Terminal', terminalSchema);
  

• Entity

  由Model创建的实体，他的操作也会影响数据库

   var terminalEntity = new terminalModel({
   	mac : '00-11-22-33-44-55', 
   	id : '123456', 
   	direct : 'vertical', 
   	version : 'V8-S628G01-LF1V001'
   });
