Abstract
The purpose of this project is to show how new technologies help the banking and
financial industries to process and retrieve data for users. The primary goal of this project is to
demonstrate the new technologies Angular JS, RESTful Web Services, and the Cassandra
database which are faster than the other conventional software frameworks. This has been
achieved by creating two software applications; one is an online banking application with the
latest technologies and the other with traditional frameworks. After examining the time taken by
the techniques to render the web page to the user, and the availability and scalability of the
software, we will understand the need for the new technologies in the banking and financial
sectors. The application that is developed should help the users, guide them and should perform
user requested transactions with zero fault tolerance; it should give precise data without losing or
showing error data. It should also provide security to the transaction. Unauthorized transactions
should be prohibited from entering the server either from UI (User Interface) or from a mid-tier
connection. The proposed application uses the Cassandra database which has high scalability and
availability. It also uses Service Oriented Architecture (SOA) for better service and performance
of the application. In the UI we use Angular JS which is fast and can handle the REST
(Representational State Transfer) Application Programming Interface CRUD(Create, Read,
Update & Delete) operations.
