Query by Example JSON document store Query By Example allows a client to specify a structure in which is used as the example, and all entities which match are returned. Implement a basic storage mechanism which allows a user to store documents in JSON format. The structure of the document may be otherwise arbitrary. The program accepts a command through stdin followed by a space, followed by a document, followed by a newline. There are three allowed commands . add, store the given document get, find all documents which have the same properties and property values as the given document, and emit them to stdout - delete, remove all documents which have the same properties and property values as the given document. The commands are all lowercase Given the input: add f"id":1, "last": "Doe", "first": "John,"location":("city": "Oakland", "state" "CA", "postalCode": "94607),"active" true) add ("id":2, "last":"Doe", "first": "Jane", "location":"city": "San Francisco", "state": "CA","postalcode": "94105"),"active" :true add f"id":3,"last" "Black","first" "Jim", "location":"city": "Spokane", "state": "WA", "postalCode": "99207","active" true) add ("id":4, "last": "Frost","first" "Jack", "location":("city":"Seattle", "state": "WA","postalCode": "98204", "active":false) get "location" ("state": "WA", "active":true) get ("id":1) Query by Example JSON document store Query By Example allows a client to specify a structure in which is used as the example, and all entities which match are returned.
