Patent ID: 8832020

Claim:
A method comprising: publishing, on a computer processor, legacy tabular data from a legacy data storage device into an object semantic model of a unified grid to create object data, the legacy tabular data associated with a plurality of business platforms of an entity, the unified grid supporting in-memory data storage; performing, on the computer processor, parallel testing on access of the legacy tabular data in the legacy data storage device and the unified grid to verify accessed data consistency; based on a successful result of performance of the parallel testing, dynamically mapping, on the computer processor, the legacy tabular data structures into a plurality of grid-based objects within the in-memory data storage of the unified grid; modifying, on the computer processor, the plurality of business platforms to access the object data on the unified grid in the legacy data storage device based on mapping of the legacy tabular data structures; modifying, on the computer processor, legacy code of the plurality of business platforms to create modified code that serves objects based on the object data instead of legacy tabular records sets; harvesting, on the computer processor, a plurality of business rules from the modified legacy code; and implementing, on the computer processor, the plurality of business rules in a rules engine and a semantic relationship between the objects in place of the plurality of business rules from the modified legacy code.
