通过映射将数据保存在firebase中>>

Question

我只是将数组传递给Firebase来存储数据，但这不是从数组查询数据的有效方法。所以，我打算以映射格式存储数据。但不确定如何做到。

{
   "ClassDetails": 
   [
     {
       "Code": "CIS695",
       "Instructor": "Dr. Antony",
       "Location": "BB444",
       "Name": "Capstone project"
     }
   ],
   "PersonalDetials": [
     {
       "Email": "[email protected]",
       "FName": "Ravi",
       "LName": "Shah",
       "Major": "MSIS"
     }
   ]
 }
想要更改此格式

{
   "ClassDetails": 
     "CIS695"{
       "Code": "CIS695",
       "Instructor": "Dr. Antony",
       "Location": "BB444",
       "Name": "Capstone project"
       }
       "CIS690"{
       "Code": "CIS690",
       "Instructor": "Dr. Smith",
       "Location": "BB444",
       "Name": "Project Management"
       }
   "PersonalDetials": 
     {
       "Email": "[email protected]",
       "FName": "Ravi",
       "LName": "Shah",
       "Major": "MSIS"
     }
 }
