build mobile app to update remote MSSQL DB

Hi, We have an existing MSSQL DB running on a remote windows machine. The machine is accessible via internet. We need a mobile (iPhone & android) application where we can update some fields in the database. For example we have customers records and we need to be able to update the credit field. We need to update some fields in different tables. Application should be flexible, we need to be able to specify the data that can be updated and the data shown on the application. For example for a customer update, we need only the name, address and credit on the screen but only the credit can be changed. Customer data must be listed in a predefined order or it should be possible to search the correct customer. In the MQSQL database, we have some views. We also need to be able to view this data in the mobile application. Communication should be secure. You can also run a small application on the windows machine to communicate with the app and to do the configuration. a nice design is a pro
