A “forward” delta data management technique uses a “sparse” index associated with a delta file to achieve both delta management efficiency and to eliminate read latency while accessing history data. The invention may be implemented advantageously in a data management system that provides real-time data services to data sources associated with a set of application host servers. To facilitate a given data service, a host driver embedded in an application server connects an application and its data to a cluster. The host driver captures real-time data transactions, preferably in the form of an event journal that is provided to the data management system. In particular, the driver functions to translate traditional file / database / block I / O into a continuous, application-aware, output data stream. In an illustrative embodiment, a given application aware data stream is processed through a multi-stage data reduction process to produce a compact data representation from which an “any point-in-time” reconstruction of the original data can be made.

A method, apparatus, and program product are provided for creating an Encoded Matrix Index for a column in a database table. An element of the column for all rows in the database table is compared to a corresponding reference value in a reference data structure, and in response to at least one value for the element of the column not matching the reference value, indicating a variation in a variation data structure and creating a value data structure. Queries executed using the Encoded Matrix Index include terms associated with a sub-column defined in a column of a database table. The variation data structure is accessed to determine whether any variation exists between rows belonging to a sub-column of the database table. If no variation exists, a value is accessed from the reference data structure; otherwise, a value for each row of the sub-column is accessed from a value data structure.

A wireless network device, such as a printer, to enter an infrastructure-type user wireless LAN as a station, has an additional access point function. A printer having an ESS-ID ‘MM’ as an initial setting is connected with a user wireless LAN, which includes an access point and a personal computer and uses a common ESS-ID ‘XX’. In this case, the procedure changes the ESS-ID set in the personal computer to ‘MM’ to establish an infrastructure-type communication with the printer. This arrangement enables the ESS-ID set in the printer to be changed to the common ESS-ID ‘XX’ for the user wireless LAN without varying the ESS-ID set in the access point. The technique of the invention ensures easy connection of any device without sufficient input interfaces to the wireless LAN.
