Abstract: Embodiments of the present disclosure relate to a database system for dynamically and automatically accessing and storing data items from multiple data sources. The system may, for example, determine data sources to access, and ways of accessing data items from those data sources, based on an indication of an analysis level and/or other analysis criteria. Further, the system may selectively and efficiently integrate data items from the multiple data sources. Selective integration of data items may be based, for example, on the indication of the analysis level and/or other analysis criteria. The system may further generate outputs of the selective integration of data items. These outputs may, for example, include specialized reports and/or user interfaces. The outputs of the system, in some implementations, may be interactive and dynamically updated in response to user inputs, for example.

Abstract: A system for measurements of merchant performance using a payment card processing system, the system includes a managing computer system of a payment card service provider, the managing computer system having a memory device capable of storing data for generating measurements of merchant performance based on payment card transactions, and a computer processor. The computer processor is configured to: receive payment card transactions from at least one merchant; store the payment card transactions for the at least one merchant; generate at least one business performance indicator for the payment card transactions of the at least one merchant; compare the at least one business performance indicator for the at least one merchant to a comparable business performance indicator; and generate a measurement of merchant performance for the at least one merchant based on the comparison of the at least one business performance indicator to the comparable business performance indicator.
