Abstract

A method for implementing a change capture system using an event publishing system as a database recovery log is provided. The method may include determining a set of data based on a description of events for which change capture is possible. The method may also include selecting at least one item of data from within the determined set of data, wherein the at least one item of data requires change capture to be performed. Additionally, the method may include identifying at least one published event, wherein the at least one published event is produced by the event publishing system. The method may include instructing the event publishing system to deliver the at least one identified published event to the change capture system. Furthermore, the method may include receiving the at least one identified published event. The method may also include processing the at least one published event.

Claims

1. A method for implementing a change capture system using an event publishing system as a database recovery log, the method comprising:

determining a set of data based on a description of events, wherein the set of data comprises a plurality of data for which change capture is possible;

selecting at least one item of data from within the determined set of data, wherein the at least one item of data requires change capture to be performed;

identifying at least one published event based on the at least one selected item of data, wherein the at least one published event is produced by the event publishing system, and wherein the at least one published event is a person event where a plurality of information related to a customer is changed in a source database;

instructing the event publishing system to deliver the at least one identified published event to the change capture system;

receiving, by the change capture system, the at least one identified published event;

extracting the at least one identified published event from a persisted store, wherein the at least one identified published event is extracted from the persisted store using an algorithm that provides log dependency information for a source database;

analyzing a plurality of information contained within the at least one identified published event;

identifying a change associated with the at least one item of selected data; and

recording the identified change to the at least one item of selected data to a repository.

2. The method of claim 1, wherein the recording of the identified change comprises recording a plurality of contextual information regarding the identified change to the at least one item of selected data, wherein the plurality of contextual information comprises a timestamp of the identified change to the at least one item of selected data and a plurality of customer information.

3. The method of claim 1, wherein the selected at least one item of data is selected by a graphical user interface (GUI) comprising a list of a plurality of table data and a plurality of column data.

4. The method of claim 1, wherein the determined set of data comprises a plurality of tables and a plurality of columns within the plurality of tables.

5. The method of claim 1, wherein the identified change to the at least one item of selected data comprises at least one of an insertion of a plurality of information to the source database;

an update to a plurality of information in the source database; and

a deletion of a plurality of information in the source database.
