Invoice/Credit Note Web Service

The overall objective of this project is to develop a web service that will receive incoming invoice/Credit Note XML’s and update them to a database. The Web Service should follow an n-tiered structure, in that there is a business tier and a data access tier behind the web service. One of the key elements of the web service is to build a framework/template web service that in the future could not only be enhanced by altered for other uses.

The overall aim of the web service is so a simple client application can send an invoice or Credit Note XML, and have it update to the relevant back end database. Again the main aim is to build a framework/template that can be expanded upon in the future.

In terms of the scope required for the project, it is limited to a simple client (VB .NET client) that will send a pre-defined invoice/Credit Note XML to a specified web service.

The main part of the project is to produce a web service that will receive the invoice/Credit Note XML, validate its contents, then either reject the XML and send an error message back to the client application (e.g. XML Response), or proceed with the processing of the XML invoice/Credit Note, and update it to a specified database.

The scope also covers the web service, interacting with a business tier and data access tier in terms of the n-tier architecture.
