Abstract: A system, a method, and a computer program product for detection and extraction of data are disclosed. A query containing a filtering parameter for extracting changed data from a plurality of resources is executed. Using the filtering parameter, first data in the plurality of resources is identified. Based on the identified first data, second data stored in the plurality of resources and associated with the identified first data is identified. The identified first data is contained in a first resource in the plurality of resources and the second data is contained in a second resource in the plurality of resources. Based on the filtering parameter, a determination is made whether at least one of the identified first data and the identified second data contain at least one change. At least one of the identified first data and the identified second data from the plurality of resources is retrieved.

Abstract: A system, a method, and a computer program product for replication of data changes are disclosed. Based on a received data query, at least one attribute of stored data is identified for replication. The attribute corresponds to at least one parameter of the received query. Data stored at a first time and data stored at a second time are retrieved. The second time is subsequent to the first time. Data stored at the first time is compared to the data stored at the second time to determine a delta difference between the data stored at the first and second times. The computed delta difference is selected for the identified attribute. The selected computed delta difference is replicated in response to the received query.
