Purpose
The Cloud Data Object (CDO) defines a protocol to manage complex business transactions when working in an n-tier application architecture. The CDO specification includes a Data Object on the client, a Data Service Catalog and a remote Data Service. The protocol is language agnostic and can be layered on existing standards-based technologies. The CDO extends mobile business apps past simple CRUD (create, read, update, delete) operations with support for transactional data synchronization and business logic invocation, something that many protocols lack. Since the client and server can be implemented in different technologies, the CDO a compelling model for integrating new clients into existing business solutions.
