Consistent Interface for Customer - Message Set 2

A distributed system operating in a landscape of computer systems providing message-based services defined in a service registry, the system comprising:

• a graphical user interface comprising computer readable instructions, embedded on tangible media, for querying information about customer data using a query by communication data, the instructions using a request;
• a first memory storing a user interface controller for processing the request and involving a message including a message package hierarchically organized as:
• a customer by communication data query sync message entity;
• a customer selection by communication data package including a customer selection by communication data entity;
• a processing conditions package including a processing conditions entity;
• and
• a requested elements package including a requested elements entity;
• and
• a second memory, remote from the graphical user interface, storing a plurality of service interfaces, wherein one of the service interfaces is operable to process the message via the service interface.

A computer readable medium including program code for providing a message-based interface for exchanging information about customers, the medium comprising:

• program code for receiving via a message-based interface exposing at least one service as defined in a service registry and from a heterogeneous application executing in an environment of computer systems providing message-based services, a first message for querying information about customer data using a query by elements, the first message including a message package hierarchically organized as:
• a customer by elements query sync message entity;
• a customer selection by elements package including a customer selection by elements entity;
• a processing conditions package including a processing conditions entity;
• and
• a requested elements package including a requested elements entity;
• and
• program code for sending a second message to the heterogeneous application responsive to the first message.
