Build app and web like ola or uber cabs

Question

Hello all

I got a requirement from a client to build an app for booking a ride like ola or uber type.

 

I am analysing the requirement and needs some improvisation in it.

 

App will contains for

1. User

2. Driver

 

For admin and support team

1. Website will be there

 

Backend

1. Web services which one to choose)

2. Database (which one is robust and fast, I am proficient in MSSql)

 

For android app, I'll use xamarin.android

 

Client also need a wallet (I have no idea for implementation) to store money and redeem it at the time of payment.

 

Can anyone guide through database architecture and some designing guidance.

 

Ineed to implement google map api for navigation ( to show moving vehicle while travelling), need to calculate distance, time, please focus some light on this.

 

Thanks

Devendra
