Need to write Visual Studio C# application with SOAP Webserice for accessing the accounting program database. The application needs to be packaged into windows install program that customers can download and install on their server. The application needs to have a simple configuration to setup database details via ODBC. The Webservice will need to provide some basic methods: - get product price and availability - get product description - get products list - get invoice list for customer - get invoice details - submit order The database access layer needs to take into account that several versions of the database may exist so each version should have a separate driver that accesses the specific fields. The data access should work by creating database views which expose the fields we need in the web service for read purposes. The writing of data should have good error messages for data validation. For now we only need one driver and will provide a sample database for development and testing.

Hello, I am reading the project description and would like to propose to use the Entity Framework (ORM) instead of the ODBC driver because this will help to make a data access layer common or better said always the same for all types of databases. Of course there can be a slight differences between databases but there exists solutions. For the rest, making windows desktop application + installer to consume the webservice is a usual task. Anyway I would like to discuss to see if there are any additional, special requirements. Kind Regards, Patrik

Hi Good day For the database layer, we can use NHibernate. NHibernate will enable you to switch between different databases and enable portability accross databases. We can develop this application with C# and NHibernate and give you installation packaged. Thanks Rinsad

Good day, i have knowledge with C# and Webservices and i have worked on several project where a webservice was used as a layer between application and database. In addition i am currently a DBA for a worldwide product with extensive knowledge with databases. Please not that especially the time is a preliminary best-case and may vary depending on details of your requirements. This is how i understand them: You have a database (may exist in several versions). My task would be to: -develop SQL scripts to create views to be used -develop Webservice to acces those views -make it possible for webservice to create orders (do i understand correctly that order submit would be an insert operation into database?). Here i would propose to use a stored procedure, which would again allow to shield webservice from potentional DB structure changes -pack the application into an installer I am interested in this project and would love to work on it with you. Looking forward working with you, Have a nice day
