you have been asked to develop a system to make restaurant reservations and to order food online

• The system should have a web interface where users can reserve tables at a restaurant, by giving the number of guests and the expected time of arrival. • There are no online payments required to make a reservation. However, the customer should register in the system prior to making a reservation. • To make a reservation, the customer has to give his/her mobile number, as the user ID. • Once a reservation is successfully made, the client is notified via SMS and email of the reservation. • In addition to the online reservations, food items can be selected from a menu and can be ordered online. • The payment for the food to be delivered can be made using credit cards or by paying cash at delivery. • The system can connect to a payment gateway for credit card transactions. The information that should be submitted includes the credit card number, amount, CVC number (3 digit number at the back of the card) and card holder’s name. • Once the payment is made for a delivery the user should be given a confirmation of the appointment via SMS and email. 1. Based on the above information, come up with a set of RESTful Web API services to implement the system. Use JSON as the message format. 2. Develop a web client to expose the Web API services to the end user. You should use asynchronous Javascript (AJAX) + JQuery / AngularJS / .NET HttpClient or a similar asynchronous web technology to improve the responsiveness of the web client. 3. Use appropriate security/authentication mechanisms to uniquely identify each user and to authenticate/authorize each user.
