Abstract:

A hierarchical filing system provides a cataloging of data stored in various locations within a memory device. An upside-down tree type structure provides a downwardly expanding cataloging structure wherein directories provide for further branchings. A branching from a directory is terminated when a file is reached. Each directory is assigned a unique directory identifier value. Then, each file or directory is coupled with the directory identifier value of its parent to provide the interconnection necessary to form the cataloging structure. The complete cataloging structure is organized in the leaf nodes of a B-Tree structure and distributed in an ascending order of the key values to provide a systematic search for a given key. Each file is capable of storing a predetermined number of location description information when data is segmented into non-contiguous segments in memory. A file extents record is used to maintain record of the further segmentation.

Abstract:

There are provided systems and methods for automatic determination of card data based on network category codes. A user may engage in a transaction with another user, such as a purchase of goods, services, or other items a merchant using a physical payment card. An online transaction processor may receive information from processing of the payment card over an electronic card network so that the online transaction processor may determine data for the payment card. The data may be determined over a time period, which may be dynamically adjusted based on additional data for the user, time period, and/or payment card. The data is further identified and determined based on network category codes for different transaction data when processed over the electronic network. Thereafter, categories of data may be selected to provide benefits back to the user's account or payment card.
