Overview of DAS. Data is stored in either databases or data files (A). DAS servers (B) offer a common interface to access that data, the DAS protocol. Users (C), can use different client types (D) including specific DAS clients, internet browsers and non-visual scripts, to access the data. Optionally, clients can access the DAS Registry (E) to retrieve a list of available DAS sources.
