46. NoSQL

47. NoSQL = Denormalization

48. Denormalization in NoSQL { "users": { "user1": { "name": "Alice"

    }, "user2": { "name": "Bob" } }, "links": { "link1": { "title": "Example", "href": "http://example.org", "submitted": "user1" } }, "comments": { "comment1": { "link": "link1", "body": "This is awesome!", "author": "user2" } } }

49. Denormalization in NoSQL { "users": { "user1": { "name": "Alice"

    }, "user2": { "name": "Bob" } }, "links": { "link1": { "title": "Example", "href": "http://example.org", "submitted": "user1" } }, "comments": { "comment1": { "link": "link1", "body": "This is awesome!", "author": "user2" } } }

52. • NoSQL cloud database • Realtime Data Sync with JSON

    Tree • Available data on offline Firebase Database

53. Cloud Firestore

54. • Stores data in documents organized in collections • Sending

    data with protobuf, which have more types • Introduced reference type, so requires less denormalization and data flattening • Indexed queries with compound sorting and filtering Cloud Firestore
