Web Service for Calculating the Probability of Returning a Loan – De-sign, Implementation and Deployment

The purpose of this paper is to describe the process of designing, creating, implementing and deploying a real web service. A basic theory approach is used to analyze the implementation of web services. An existing profit model is used. Its business logic is integrated within a web ser-vice. Another desktop application is created to demonstrate the use of the recently created web service. This study shows a methodology for fast development and deployment of web services. The methodology has wide practical implications – in credit institutions and banks when giving a loan. This study is the first of its kind to show the design, implementation and deployment of a web service for calculating the probability of returning a loan. The methodology may be used for the encapsulation of other business logic into web services.
