A data connection is a dynamic link that is used to receive or submit data between a Microsoft InfoPath form and data that is saved outside the form, such as a SharePoint server, Web service, or database.

Data connections overview A data connection is a dynamic link that is used to receive or submit data between a Microsoft InfoPath form and data that is saved outside the form, such as a SharePoint server, Web service, or database. For example, in an order form that contains a list of available products, the static list of product names could be saved in the form. However, any time a product is added or removed, the product list in the form must be updated.

To make sure that the form stays up-to-date, save and maintain the product information outside the form. Create a data connection to add this information to the form when users fill out the form. The benefit of using a data connection to retrieve the product information is that this information can be saved in a single place that multiple forms can link to. Also, you are assured that users always have the latest information when completing a form.
