Abstract

A method and associated system for managing rules that synchronize operations of a source system and a target system. A set of linked worksheets is generated as a function of the internal logic of the synchronization rules and of worksheets that represent data models of the source and target systems. These generated worksheets describe and relate data elements of the data models, extrinsic data that is stored externally to the source and target systems, and logical procedures performed by the synchronization rules. When the source data model, the target data model, or a logical procedure is revised, the linked worksheets are updated in response to the revision and these updates automatically propagate across the synchronization rules and across other components of the source system, the target system, and the synchronization mechanism.

First claim

What is claimed is:

1. A method for automatically managing a set of synchronization rules that resolve inconsistencies between a source repository of production data managed by a source system and a target repository of production data managed by a target system, wherein a source data worksheet represents a logical organization of the source repository, a target data worksheet represents a logical organization of the target repository, a record of the source data worksheet describes a logical source data element comprised by the logical organization of the source repository, a record of the target data worksheet describes a logical target data element comprised by the logical organization of the target repository, and a first synchronization rule of the set of synchronizations rules instructs a processor of a computer system how to resolve a first inconsistency between the logical source data element and the logical target data element, the method comprising:
the processor generating a source-to-rule mapping worksheet, wherein a first record of the source-to-rule mapping worksheet associates the logical source data element with the first synchronization rule,
wherein the first synchronization rule is further associated with a second logical source data element comprised by the logical organization of the source repository,
wherein a second record of the source-to-rule mapping worksheet associates the second logical source data element with the first synchronization rule, and
wherein the first record of the source-to-rule mapping worksheet and the second record of the source-to-rule mapping worksheet each identify a total number of logical source data elements associated with the first synchronization rule;

the processor generating an extrinsic data-to-rule mapping worksheet, wherein a record of the extrinsic data-to-rule mapping worksheet is capable of associating an extrinsic data element with the first synchronization rule, and wherein the extrinsic data element is comprised by neither the source repository nor the target repository;
the processor generating a target-to-rule mapping worksheet, wherein a record of the target-to-rule mapping worksheet associates the logical target data element with the first synchronization rule;
the processor generating a rule-logic worksheet, wherein a record of the rule-logic worksheet associates the first synchronization rule with a logical procedure by which the processor may resolve the first inconsistency; and
the processor automatically responding to a revision to a first revised record of a first worksheet by automatically revising a second revised record of a second worksheet, wherein the first worksheet is distinct from the second worksheet, the first worksheet and the second worksheet are selected from the group consisting of the source data worksheet, the target data worksheet, the source-to-rule mapping worksheet, the extrinsic data-to-rule mapping worksheet, the target-to-rule mapping worksheet, and the rule-logic worksheet, and wherein the automatically revising is performed by means of a linkage between the first revised record and the second revised record.

2. The method of claim 1 , further comprising:
the processor analyzing a subset of the source data stored in the source repository and a subset of target data stored in the target repository; and
the processor updating the source data worksheet and the target data worksheet as a function of the analyzing.

3. The method of claim 1 , further comprising:
the processor receiving an indication of a revision to the logical organization of the source repository, to the logical organization of the target repository, or to the first synchronization rule;
the processor responding to the receiving by further revising a related worksheet selected from the group consisting of the source data worksheet, the target data worksheet, and the rule-logic worksheet; and
the processor automatically updating a linked worksheet selected from the group consisting of the source data worksheet, the target data worksheet, the source-to-rule mapping worksheet, the extrinsic data-to-rule mapping worksheet, the target-to-rule mapping worksheet, and the rule-logic worksheet, in response to the further revising the related worksheet, wherein the linked worksheet is distinct from the related worksheet.

4. The method of claim 1 ,
wherein the logical procedure comprises copying an element of source data comprised by the source repository to a target storage location comprised by the target repository, and
wherein the element of source data is associated with the logical source data element and the target storage location is associated with the logical target data element.

5. The method of claim 1 ,
wherein the record of the extrinsic data-to-rule mapping worksheet associates the extrinsic data element with the first synchronization rule,
wherein the extrinsic data element comprises a distinct element of data associated with an external information source;
wherein the external information source is distinct from any component of the source system, the target system, the source repository, and the target repository; and
wherein the logical procedure of the first synchronization rule depends upon a value of the extrinsic data element.

6. The method of claim 1 , wherein the logical procedure is a business function, wherein the business function is selected from the group consisting of a business process, a convention or standard of operation, and a business method, the method further comprising:
the processor receiving an indication of a revision to the business function; the processor responding to the receiving by further revising the record of the rule-logic worksheet; and
the processor automatically updating a linked worksheet selected from the group consisting of the source data worksheet, the target data worksheet, the source-to-rule mapping worksheet, the extrinsic data-to-rule mapping worksheet, and the target-to-rule mapping worksheet.

7. The method of claim 1 , further comprising providing at least one support service for at least one of creating, integrating, hosting, maintaining, and deploying computer-readable program code in the computer system, wherein the computer-readable program code in combination with the computer system is configured to implement the generating the source-to-rule mapping worksheet, generating the extrinsic data-to-rule mapping worksheet, generating the target-to-rule mapping worksheet, generating the rule-logic worksheet, and the automatically responding by automatically revising.

8. A computer program product, comprising a computer-readable hardware storage device having a computer-readable program code stored therein, said program code configured to be executed by a processor of a computer system to implement a method for automatically managing a set of synchronization rules that resolve inconsistencies between a source repository of production data managed by a source system and a target repository of production data managed by a target system, wherein a source data worksheet represents a logical organization of the source repository, a target data worksheet represents a logical organization of the target repository, a record of the source data worksheet describes a logical source data element comprised by the logical organization of the source repository, a record of the target data worksheet describes a logical target data element comprised by the logical organization of the target repository, and a first synchronization rule of the set of synchronizations rules instructs a processor of a computer system how to resolve a first inconsistency between the logical source data element and the logical target data element, the method comprisin
