We here aim to provide the restaurants with a tablet menu that would remend dishes based on are mendation algorithm which has not been implemented elsewhere. In addition to this we run the app on an Android based tablet amp。 Cosine Equation We used Jaccard`s coefficient in our models. Technologies The technologies being used to build the system are cutting and largely open source. Open source technologies help in keeping the costs in check, thus enabling the various establishments to use this setup without any cause of concerns with regards to the costs involved. Amazon Web Services has a very effective and inexpensive service known as Elastic Cloud Compute which allows one to setup servers on the fly with the specifications one requires. We will be using the same (or similar) service to keep the costs down and maintain scalability. The server uses software known Nginx. Nginx [engine x] is an HTTP and reverse proxy server, as well as a mail proxy server, written by Igor Sysoev. For a long time, it has been running on many heavily loaded Russian sites including Yandex, , VKontakte, and Rambler. According to Netcraft nginx served or proxied % busiest sites in February 2020. The database uses the ever popular MySQL as its DBMS. The web services mentioned earlier are powered by a web framework called Symfony that uses PHP and an ORM called Doctrine. OAuth and SSL can and will be used to implement security. The tablets supplied to the patrons will be running Android OS.

It could be used by an 8 year old or an 80 year old person, from varying cultures and background. This ensures the need for a design that is intuitive, user friendly and beautiful thus making it a pleasure to use. Scalable The system has the potential of being used by millions of users at any given time, with possible peaks at various rush hours at the establishments this may be implemented at. Thus, the system will have to be scalable and should be able to acmodate as many users and as much data as required. Secure Since private information about so many businesses and individuals will be stored in our database. We will need to ensure that the whole system the web service, the app, the database as well as the server be secure from external as well as internal threats. Assumptions The success of the proposed system is based on the following assumptions that: 1. End users should be able to use tablets. 2. Network connection will always remain stable.
