The document discusses using the Cloud Data Management Interface (CDMI) for more than just file storage. It outlines how CDMI capabilities like its RESTful interface and use of JSON could enable it to support a variety of data-driven applications beyond files. Examples mentioned include databases, calendars, email, documents, wikis, and sensor data. The document also describes how CDMI could provide a common data management approach across cloud applications and potentially serve as a document interface for cloud computing. It notes some missing CDMI features and concludes that CDMI is a flexible technology capable of supporting many types of data applications.

 Queries, Stored Procedures, Views, Tables,
Database
 Rows Special Case and Fields Special Case
Rows Special Case and Fields Special Case.
 Dual Mapping – Container and Object
 Object When fields are simple
 Container Fields are Complex. ie a container or
object in a blob.
