Abstract: A data backup manager links data backup robustness to an external state. The data backup manager monitors the external state. Responsive to the external state, the data backup manager adjusts parameters controlling data backup, such as backup frequency, backup content, and backup retention time. The data backup manager can increase these parameters responsive to an increase in an external distress state level, and decrease them in response to a decrease in the external distress state level.

Abstract: This disclosure describes systems, methods, and apparatus for expanding a row or column in an existing report, sourced from a relational database, where a column or row, respectively, of an opposite axis has already been expanded. Such a need often arises in reports sourced from a SQL database, and overcomes the storage-draining need to precompute all possible arrangements of data from the database prior to displaying the report. In some embodiments, a client can make a request for a multi-axis expansion, and a server can create filters for use in sub queries, one for each level of expansion in an axis of the report opposite to the axis where expansion is requested, the sub queries can be executed, results sets can be combined/formatted to form a new report, and the new report can be returned to the client for stitching into the existing report.

Abstract: A network database system wherein clients of subscribing entities are authorized network access to reliable documents that are identified by each entity as being relevant to clients of that entity. Features that can be included in the system are customization of the documents to reflect sourcing by particular subscribers, automated formatting of the documents for storing in a network database, client access facilitated by subscriber-maintained databases, and the avoidance of cookies remaining on clients' computer hard drives following document access. Also disclosed is a method for processing repeated data requests on a distributed computer database.

Example techniques may include associating the data with at least one geographical characteristic, and allocating the data to at least one of the plurality of storage devices based on the geographical characteristic.

Abstract: A method is provided for compressing results of a join query. A join order of a result set is determined from the join query, where the result set includes a plurality of tuples. A plurality of dictionary entries for the result set is received. A nested hierarchy of dictionaries is created based on the join order and the dictionary entries. A plurality of encoded tuples is received. The nested hierarchy of dictionaries is used by a processor to decode the plurality of encoded tuples so as to produce the plurality of tuples of the result set.

Abstract: In one embodiment, a web service engine server 104 may predict a successive action by a user based on an entity reference 302. The web service engine server 104 identifies an entity reference 302 in a data transmission caused by a user. The web service engine server 104 determines from the data transmission a user intention towards the entity reference 302 using an intention model based on a transmission log. The web service engine server 104 predicts a related successive web action option 522 for the entity reference 302 based on the user intention.

Abstract: Techniques for improving data compression of a storage system in an online manner are described herein. According to one embodiment, in response to a sequence of data to be stored, the sequence of data is partitioned into a plurality of data chunks according to a predetermined chunking algorithm. A sketch for each of the data chunks is generated based on one or more features extracted from the data chunk. Each of the data chunks of the sequence of data is associated with one of a plurality of groups based on the sketch, wherein each group is represented by a sketch. The data chunks of each group are compressed and stored in a compression region of the storage systems, such that similar data chunks are compressed and stored in the same compression region.

Abstract: A system aggregates documents from multiple genres of data sources, where the multiple genres of data sources may include news sources, blogs, news groups, and discussion groups. The system groups the aggregated documents into one or more clusters, where each of the one or more clusters relates to a same topic. The system further classifies each of the one or more clusters into one or more taxonomies and archives each cluster with its respective classifications.

Abstract: A method for identifying a result responsive to a current location of a client device includes receiving, form a client device and at a host, a search query that includes a point of interest and a current location of the client device. The method also includes automatically updating the search query as the current location of the client device changes and instructing the host to identify a potential location associated with the point of interest and located within a user-defined proximity from the current location of the client device.

Abstract: A system for providing real-time streaming of data in non-POSIX formats to systems in POSIX formats in the general context of system backup and recovery. The system uses an index to manage storage and retrieval of data in non-POSIX formats. While retrieving the backup, the system presents a virtual volume to a hypervisor or other similar device to create a virtual machine that allows the user to make read or write requests with respect to the backup before it is completely restored. The system merges any changes to the virtual volume, due to write requests, with the complete, backed-up volume. In one embodiment, a system backup is stored in object storage and can be recovered in real-time, allowing a user to access and use the system before it has finished recovering.
