The role of web applications in today’s day-to-day activities has been increased rapidly. The dependency upon these applications was abnormally raised. The aim of web applications is to serve the users with better quality. To achieve this user satisfaction, any web application should provide a reliable service. In general many web applications process huge amount of data. The quality of any web application depends upon various factors like ease-to-use, look and feel, security, performance and reliability. The reliability of web application is more complex when compared to stand-alone applications. In order to assess or improve the reliability of any system we use either software reliability estimation models or software reliability growth models (SRGM). The vital failure data of any software based application or system will be obtained during the test phase. In this paper we have considered the dataset of a weather forecasting web application and computed the reliability of this application by using Non-Homogeneous Poisson Process (NHPP) model. Based on the results obtained we noticed an improvement in the reliability of the software application.
