Database Replication Error Handling via Business Logic Rules

The patent introduces an intermediary error handling mechanism that sits between the replication tool and the target database. This intermediary captures replication errors, matches them to appropriate handling rules from a rule set, and applies corrective actions. This mediator layer allows the replication process to continue automatically while ensuring data accuracy by resolving compatibility issues through predefined business logic rules.

The patent applies preliminary action by pre-defining a comprehensive set of error handling rules that encode business logic specific to the organization's data requirements. These rules are established before the replication process begins and are stored in an accessible rule set. When replication errors occur, the system quickly matches them to the appropriate pre-defined rule, enabling accurate business-logic-specific error correction without interrupting the replication continuity.

The patent segments the error handling functionality into distinct, modular components: an error capture mechanism that identifies replication errors, a rule matching engine that selects appropriate handling rules from a structured rule set, and an execution component that applies the selected rules. This segmentation allows custom business logic to be integrated in a structured, maintainable way, improving error correction capability while managing system complexity through clear separation of concerns.
