Jason data consists of <object> and <array>.Data in a document is the form of key and value pair.Data is separated by commas.Curly bracket {  } hold objects. Box bracket [] represent the array.if you want to store more than one document or object you will use the array.The following example that explains Embedded document <objects> and <array>.
