43. Firebase Database
44. • NoSQL cloud database • Realtime Data Sync with JSON Tree • Available data on offline Firebase Database
45. Firebase Database
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" } } }
50. 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" } } } Join data in client

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
