title: Is it necessary to append Field-Value pairs in MongoDB?
body: <p>This is related to MongoDB. I have two documents defined in the same collection as follows. The data is related but that is spread across 2 documents. Will there be a problem in Querying a particular field from this collection or should we create a document and keep appending new field value pairs in addition to existing "Field:value" pairs similar to document #3</p>
  
  <h1>1</h1>
  
  <p>{
      "name":"David",
      "age":30,
      "team":"ManU"
  }</p>
  
  <h1>2</h1>
  
  <p>{
      "gender":"Male",
      "profession":"FootballPlayer"
  }</p>
  
  <h1>3</h1>
  
  <p>{
      "name":"David",
      "age":30,
      "team":"ManU",
      "gender":"Male",
      "profession":"FootballPlayer",
      "Country":"England"
  }</p>
