US Classification:

707 6, 707 9

Abstract:

A method, system and computer program product for controlling access to data files stored in a repository is disclosed. The invention entails a determination of the requested file's availability and the authorization and authentication of the requester. A requester may specify the format in which they wish to receive the data file, and facilities are provided for translating the requested file to the requested format if the file is not stored in the requested format. Advantageously, the invention provides a repository for retaining responses to requests so as to minimize successive requests against the repository for the same data file. Moreover, in such instances wherein a requested data file requires a format translation, a facility is provided for determining the correct stored file format to use as the input for the format translation. Such a determination may be based upon criteria such as minimizing data lost as a result of the translation or minimizing processing required in performing the translation.

International Classification:

H04Q 11/00

US Classification:

370360

Abstract:

A system and method for the efficient use of satellite radio modems and satellite bandwidth is disclosed. In the system and method, a satellite radio modem is used for PRACH requests, each PRACH request occupying 31. 25 kHz in a packet data transfer channel. The packet data transfer channels can be either 125. 0 kHz or 156. 25 kHz. Therefore, four PRACH requests can be transmitted in any one packet data transfer channel. The packet data transfer channels are broken into eight time slots, and one time slot in each channel (either the odd frame or even frame) is dedicated to a PRACH request. A satellite radio modem for PDCH transfers is dedicated for each channel. The satellite radio modem assigned to receive the four PRACH requests is timeshared over 16 channels, thereby reducing the amount of satellite radio modems that would otherwise have been needed, had the PRACH request transmissions utilized a dedicated modem for each PRACH request, for each channel.

Inventors:

Sanjay Gupta - Poughkeepsie NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707 7, 707203

Abstract:

A method for increasing performance of non-relational databases with reduction in view index sizes is provided. One or more user views are provided in addition to the master view having all hierarchical/categorized data. User views are created having a subset of this hierarchical/categorized data that significantly reduces index size and improves performance. The indexes of the user view are associated with the indexes of the master view. This method improves view caching by dividing view cache into partitions based on the types of view, each with different priorities and management techniques. The master view may have a higher priority and may be used by servers while the user view may have lower priorities and may be used by users and client applications. In this way, legacy non-relational databases may continue to be suitably maintained with acceptable performance and avoiding potential cost and risk of migrating to a relational database.

International Classification:

G06F 17/30

US Classification:

707 6, 707 9, 707 10

Abstract:

A method, system and computer program product for controlling access to data files stored in a repository is disclosed. The method includes receiving a request for a data file from a requester. The request specifies a data format preference for receiving the data file. The requested data format is different than either of a data format used to create the data file and a data format in which the data file is stored at the time of the request. The method also includes determining if the requester is authorized to access the requested data file and translating the requested data file from a stored data format into the requested data format responsive to receiving the request if the stored format differs from the requested format. The method further includes making the translated data file accessible to the requester if it is determined that the requester is authorized.

US Classification:

707 2, 707 1, 707100, 707101, 707103, 709203

Abstract:

A method and system is provided that optimizes performance in non-relational databases. A method includes: sorting and categorizing a first set of columns within a view of the non-relational database; marking a second set of columns within the view as if the second set of columns were already sorted and categorized prior to actual sorting and categorizing of the second set of columns, the second set of columns including all columns exclusive of the first set of columns; sorting and categorizing at least one column of the second set of columns in response to performing a query on the at least one column; maintaining the first set of columns in a portion of cache; and maintaining the at least one column of the second set of columns in another portion of cache. In the method, the second set of columns is visible as collapsed data.

Inventors:

Sanjay Gupta - Poughkeepsie NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707753

Abstract:

A method and system is provided that optimizes performance in non-relational databases. According to one aspect, view index size is kept at a level that optimizes performance by categorizing and sorting only a subset of the columns contained within the corresponding view. The remaining columns are marked as having been categorized and sorted, but are not actually categorized and sorted until these columns are queried.
