IndexDB initialization data

var myDB={
    name:"univisity",
    version:1,
    db:null,
    ojstore:{
        name:"students",//
        keypath:"id"//
    }
};
var INDEXDB = {
        indexedDB:window.indexedDB||window.webkitindexedDB,
        IDBKeyRange:window.IDBKeyRange || window.webkitIDBKeyRange,//
        openDB:function(dbname,dbversion,callback){
            //(ObjectStore)
            var self = this;
            var version = dbversion || 1;
            var request = self.indexedDB.open(dbname,version);
            request.onerror = function(e){
                console.log(e.currentTarget.error.message);
            };
            request.onsuccess = function(e){
                myDB.db = e.target.result;
                console.log(":"+myDB.name+" version"+dbversion);
            };
            request.onupgradeneeded=function(e){
                var db=e.target.result,transaction= e.target.transaction,store;
                if(!db.objectStoreNames.contains(myDB.ojstore.name)){
                    //
                    store = db.createObjectStore(myDB.ojstore.name,{keyPath:myDB.ojstore.keypath});
                    console.log(":"+myDB.ojstore.name);
                }
            }


        }
}
INDEXDB.addData(myDB.db,myDB.ojstore.name,students);

just looked at the indexDb, above code initialization page to create a storage space for univisity in indexdb, and create a data table for students in this space. I want to create another data table for teachers. How should I write it?
