An external list is a key building block for SharePoint solutions based on external data. You can read and write external data with the familiar experience of using a SharePoint list. An external list looks and behaves a lot like a native list, but there are some differences in behavior. For example, you can create views and use calculated values with formulas, but not attach files or track versions.
Note:Â You can also create an external list by using SharePoint Designer 2010, which enables you to replace the default forms with InfoPath forms.

What do you want to do?
Before you begin
Working with external data requires several pre-requisite tasks to enable secure access to the data. The following information can help you plan your next steps. Also, if you experience problems trying to work with external data, this information can help you identify the issue. To access external data, you or an administrator must do the following:
Prepare the external data source   An administrator may need to create an account and provide permissions to the data source to ensure that the right people have access to the data and that the data does not end up in the wrong hands. In an external database, the administrator may also want to create specific tables, views, queries, and so on to limit the results to just what is needed and to help improve performance.
Configure SharePoint services and accounts   An administrator must activate Business Data Connectivity Services and Secure Store Service.
Configure Secure Store Services   An administrator must do the following: determine the best access mode for the external data source, create a target application, and set the credentials for the target application.
Configure Business Data Connectivity Services   An administrator must ensure that the user who creates the external content type has permission to the Business Data Connectivity metadata store and that appropriate users have access to the external content type that the external list is based on.
Create an external content type   A user must define an external content type which contains information about connections, access, methods of operation, columns, filters, and other metadata used to retrieve the data from the external data source.
