Title: METHOD AND SYSTEM FOR PERFORMING COMPUTATIONS IN A DISTRIBUTED SYSTEM
Abstract: A data management system includes a first consistency zone, a second consistency zone, and a repository manager. The repository manager identifies a calculation event for a derived object of the second consistency zone, the derived object includes a cross-zone reference to the first consistency zone; and in response to identifying the calculation event: identifies an object in the first consistency zone associated with the cross-zone reference; sends a remote object request, to the first consistency zone, for the object with reference to an event of the first consistency zone specified by the cross-zone reference; obtains the object after sending the remote object request; and obtains a derived object instance based, at least in part, on a computation specification of the derived object and the object.

number: 7
text: The data management system of any preceding claim, wherein the event is associated with a past state of the first consistency zone.
number: 8
text: A method for processing data in a data management system comprising a first consistency zone and a second consistency zone, comprising:
number: 9
text: The method of claim 8, the method further comprises:
number: 10
text: The method of claim 9, wherein obtaining the second object based on the portion of the events comprises:
number: 11
text: The method of claim 8, wherein obtaining the second object based on the portion of the events comprises:
number: 12
text: The method of any of claims 8 to 11, wherein the method is performed by a repository manager that is part of the second consistency zone.
number: 13
text: The method of any of claims 8 to 12, wherein the method is performed by a repository manager that does not manage the first consistency zone.
number: 14
text: The method of any of claims 8 to 13, wherein the event is associated with a past state of the first consistency zone.
number: 15
text: A computer program comprising computer readable program code, which when executed by a computer processor causes the computer processor to perform a method as set out in at least one of claims 8 to 14.
