Grocery shopping can be a nightmare Some typical problems:

Difficulty in sharing the shopping list One person adding something to the list and

Methodology

Requirements Gathering Important to know how different people shop

based on the household they come from▪ Do user interviews

Usability Testing Need to know if people can use the interfaces

easily while mobile▪ Prototype Interfaces will be developed and tested

Back-end

A Web Application with a database and an API through which the front-ends can access information stored in the database

Located on same machine as the Web server

Run on Tomcat Will use SOAP to communicate

information between modules. Carries out the business logic

Back-end: Success Factors

Retrieve information from the database on request from either interface

Translate data from the database to XML Send and receive messages to/from both

the mobile interface and the Web interface in XML

Perform statistical analysis on user data and present the results to either user interface

Web Interface

Will be developed using modern Web-development techniques and technologies Such as AJAX

Will be a combination of client-side and server-side programming

Will communicate with back-end using SOAP

fully implemented and function properly Users consider the interface to have good

aesthetics and be easy to use The interface performs operations in a

acceptable timeframe User achieve their tasks with a low

number of clicks
