    //insertOne
    db.collection("App").insertOne(data1,function (err,data) {

        if(err!=null){
            return console.log(err);
        }
        console.log(data.ops[0]);

    //insertMany

var Data=[data1,data2];

db.collection("App").insertMany(Data,forceServerObjectId=true,function (err,data) {

        if(err!=null){
