Patent ID: 8818935

Claim:
A collaborative data management system for engineering, design, and construction (EDC) projects, comprising: a storage medium storing a plurality of EDC data objects and a plurality of relationship objects; wherein each of the relationship objects represents a relationship between ones of the plurality of EDC data objects; wherein the plurality of EDC data objects includes: (i) a first EDC data object that represents a first value for a first parameter, the first value defined by a first user; and (ii) a second EDC data object that represents a second value for the first parameter, the second value defined by a second user; wherein the plurality of relationship objects includes a first relationship object that represents a priority relationship between the first EDC data object and the second EDC data object, wherein the priority relationship is defined as a function of a life-cycle phase of an EDC project; a processor communicatively coupled with the storage medium; a display and input device communicatively coupled with the processor; and executable code communicatively coupled with the processor and configured to: (i) display the plurality of relationship objects on the display; (ii) allow a user to manage synchronization of the EDC objects with the input device; and (iii) redefine the first relationship object during the life-cycle of the EDC project.
