Abstract: Techniques for constructing query operations associated with a report specification are described. The query operations may include a mixture of multidimensional operations and relational operations. The application of the query operations are sequenced with the computing device to reduce or eliminate certain complexities and ambiguities during generation of reports, thereby providing an improved experience for user. For example, any multidimensional rollup operation may be applied to the multidimensional representation of the data within a first timeframe and that any aggregation operation and second level filtering are applied within a second timeframe subsequent to the first timeframe. A report may be output based on a resultant data set produced by application of the query operation in accordance with the sequencing.

Abstract: A method of synchronizing a virtual file system is implemented at a computing device. The virtual file system has a hierarchical tree structure including a plurality of tree nodes, each tree node having associated metadata and corresponding to a respective component of the virtual file system. Upon receipt of a request to generate a revision of a virtual file system in at least one storage device, the computing device serializes each tree node's associated metadata into an object, generates an object ID from the serialized object, and stores the object in the storage device if the object ID is not found in an object-storage mapping table associated with the virtual file system. Finally, the computing device inserts the object ID into the object-storage mapping table and stores the object-storage mapping table in the storage device after processing the last tree node.

Abstract: A method for connecting to a web service includes selecting a web service, selecting a server among one or more servers capable of running the selected web service, determining a real address for the selected web service running on the selected server and connecting to the selected web service running on the selected server using the determined real address.

Abstract: A method of recovering information missing from a virtual file system is implemented at a computing device that is communicatively connected to one or more storage devices. Upon receipt of a request for a file associated with an instance of the virtual file system, the computing device retrieves a set of blocks associated with the file from one of the storage devices and identifies one or more of the set of blocks as missing blocks after failing to retrieve the missing blocks from the storage devices. For each missing block, the computing device retrieves one or more parity blocks from one of the storage devices and computes the missing block by applying a predefined recovery scheme to the retrieved parity blocks. Finally, the computing device reconstructs the requested file using the computed missing blocks and other blocks associated with the requested file.

Abstract: A method of constructing an entity profile, having private and public portions with different access restrictions, commences with the assignment of a confidence level to content within an electronic document. The electronic document may be associated with the first entity (e.g., may have been authored by or addressed to the first entity). The content may furthermore potentially be descriptive of the first entity. If the confidence level assigned to the content is less than a predetermined threshold, the content is automatically rejected for inclusion within the entity profile. On the other hand, if the confidence level assigned to the content exceeds the predetermined threshold, the content is included within the private portion of the entity profile. Thereafter, the content is automatically presented to the first entity for authorization, by the first entity, for inclusion of the content within the public portion of the profile.

Abstract: A computer-implemented method is disclosed for visualizing data relationships between components of a project for identifying potential duplication of selected components. One of the components is data collection assignments.

Abstract: Methods (600-900) for optimizing performance of systems (100, 200). The methods involve determining if a device (108, 1081, 1082, . . . , 108N) has been deployed as a standalone device or a cluster device. The determination can be based on a value of a flag stored in the device (e.g., an appliance) or contents of device registration information stored in a master device of a cluster of devices. The methods also involve automatically delegating data management operations to a centralized Memory Management System (MMS) or a distributed MMS (210) based on results of said determination. The centralized MMS (110) performs relational database management operations (e.g., SQL operations) in response to said data management operations being delegated thereto. The distributed MMS performs grid database management operations (e.g., non-SQL based operations or key-value based operations) in response to said data management operations being delegated thereto.

Abstract: For automatically committing a file of a file system to a WORM committed state when the file has not been modified for a certain period of time, a file server maintains a list of file identifiers and periodically scans the list to check whether or not the certain period of time has expired for each file on the list. If so, the file is committed to the WORM state. The file server also enforces an in-place lock in response to a client request to modify or delete a file when the certain period of time is found to have expired for the file. A minimum modify time and a maximum modified time are included in each entry of the list of file identifiers in order to skip entries and to reclaim memory of entries during the periodic scan.

Abstract: Various embodiments for operating a transformation system, capable of transforming a logical data object (LO) to a transformed logical data object (TLO), are provided. In one such embodiment, an open LO request to a certain LO and addressed by the at least one client to the at least one storage device, is intercepted. An identifier (ID) in a header of a TLO corresponding to the requested LO and stored in the at least one storage device, is obtained. The obtained ID is used to characterize the TLO and the LO. A determination is made whether the transformation system handles at least one open LO characterized by an ID with a same value as the obtained ID. The requested LO is opened if at least one open LO is not found. An instance corresponding to the intercepted open LO request is generated. The instance is associated to the obtained ID.

Abstract: A method for forming a virtual file system associated with a distributed storage system is implemented at a computing device communicatively connected to the distributed storage system. The computing device retrieves one or more metadata blocks associated with the virtual file system from the plurality of storage devices. After rendering a commit tree for the virtual file system, the computing device builds an instance of the virtual file system by traversing a plurality of directory nodes and file nodes associated with the tree in a recursive manner. For a respective directory node, the computing device creates a directory in accordance with the metadata associated with the directory node; for a respective file node, the computing device retrieves one or more data blocks from the plurality of storage devices in accordance with the metadata associated with the file node and creates a file using the retrieved data blocks.

Abstract: A method of resolving conflicts between revisions to a distributed virtual file system is implemented at a computing device that is communicatively connected to a plurality of storage devices. The virtual file system at the computing device has a first revision of the virtual file system. Upon receipt of a request to synchronize the first revision of the virtual file system with the storage devices, the computing device retrieves one or more blocks from the storage devices, which are associated with a second revision of the virtual file system. The computing device then merges a first component of the first revision with a corresponding component of the second revision if a first predefined condition is met or identifies a second component of the first revision as being conflicted with a corresponding component of the second revision if a second predefined set of conditions is met.

Abstract: Embodiments are directed towards identifying auto-folder tags for messages by using a combinational optimization approach of bi-clustering folder names and features of messages based on relationship strengths. The combinational optimization approach of bi-clustering, generally, groups a plurality of folder names and a plurality of features into one or more metafolders to optimize a cost. The cost is based on an aggregate of cut relationship strengths, where a cut results when a relationship folder name and feature are grouped in separate metafolders. Furthermore, the plurality of folder names and the plurality of features are obtained by monitoring actions of a plurality of users, where the folder names are user generated folder names and features are from a plurality of messages. The metafolders may be used to tag new user messages with an auto-folder tag.

Also provided is a method for decompressing results of a join query.

Abstract: Techniques used in an automatic failover configuration having a primary database system, a standby database system, and an observer. In the automatic failover configuration, the primary database system remains available even in the absence of both the standby and the observer as long as the standby and the observer become absent sequentially. The failover configuration may use asynchronous transfer modes to transfer redo to the standby and permits automatic failover only when the observer is present and the failover will not result in data loss due to the asynchronous transfer mode beyond a specified maximum. The database systems and the observer have copies of failover configuration state and the techniques include techniques for propagating the most recent version of the state among the databases and the observer and techniques for using carefully-ordered writes to ensure that state changes are propagated in a fashion which prevents divergence.
