What is Firebase? BaaS ( Backend-as-a-Service ), which powers the backend of the App / Website Main Features Drive: Small businesses, Shorten development cycles, avoid repeated framework development.

What is NoSQL? not only SQL database. Non-relational, distributed, open-source, and horizontally scalable. Drive: Big Data, Cloud Technology, bad performance of traditional relational databases.

When collapse NoSQL have low requirement on consistency of the structures of Data, can be horizontally scaled. Modifying the data schema wouldn’t require a change on the whole database

Data Stored as JSON

Localization in iOS Apple provides developers with thorough definitions of its APIs. In this research,CLLocation and CLLocationManager class in Core Location Framework are used. Steps: 1. adopt protocol in class definition and set delegate to itself. 2. set desired accuracy and event filter 3. start tracking, and get data via didChangeAuthorization version of LocationManager()

How the underlying GPS system works: Global Positioning System: a network of about satellites orbiting Earth. Whenever you are on the planet, there are at least four GPS satellites that are ‘visible’ at any time. Each one transmits information about its position and the current time at regular intervals. These Data are received by the GPS receiver. Once the receiver receives at least three satellites’ data, GPS receiver can pinpoint the location using a process called ‘Trilateration’.
