Create an online database with updates fed by xml

This is a straight forward project to create an online customer database - that can be updated/parsed with feeds sent to it by XML feeds online in a secure manner. The XML feed has two schema - but the fields are very similar BACK-END This can be secured by SSL and a password that comes while the XML feed is being sent out - so no bogus data goes to the database FRONT END ADMIN CONTROL There needs to be a admin console that controls the system We need to add other users (admin) and non-admin - with passwords and username We also need to control for each user - what details of a customer record they can access. For example, with some employees, we may want to restrict access to phone number or even email records We also want to log what a non-admin user is accessing, especially if its a high number of searches of the system. SEARCH All users may need to search for a customer's details - such as by order number, email or even zip code This needs to be tight - as we want to restrict how many records come up as a security feature to prevent any copying/ harvassing of the data by any user, as data security is paramount SALES PERFORMANCE We need a way for users to enter sales that they have made - by marking an existing order on the system We need to then be able to generate reports for each user during any interval in the admin console MAINTENANCE We need to backup the data regularly and keep it clean, and other periodic maintenance I have attached some documents that provide background of the XML and some suggestions on how it may work Note, we already have existing system but we dont have the sales control or central monitoring on it, so a new system is required thanks Sam
