Abstract: A multi-version concurrency control method in a database and a database system, where the database system sets a data page link of a page, where the data page link includes a page pointer, and a page pointer is used to point to another version page prior to a last operation on the version page. Hence, when a page in the database is read, and when a timestamp of a current version page is greater than a timestamp of a read transaction, page-level rollback may be directly performed according to a data page link of the page that is requested to read to roll back to a page that needs to be read, which facilitates queries for data on each version page in the database, and the database system may implement record rollback efficiently.

Abstract: A circuit arrangement, program product and method are provided for resetting a dynamically grown Accelerated Data Structure (ADS) used in image processing in which an ADS is initialized by reusing the root node of a prior ADS and resetting at least one node in the prior ADS to break a link between the reset node and a linked-to node in the prior ADS. By doing so, the memory allocated to the prior ADS may be reused for the new ADS, without having to clear or wipe out all of the allocated memory. In addition, in some instances, given the similarity of many image frames, often some or all of the node structure of a prior ADS may be reused for a new ADS, requiring only the contents of nodes to be cleared, instead of having to clear out all of the nodes in the prior ADS. As a result, the processing overhead associated with initializing a new ADS can be significantly reduced.

Abstract: File system sharing in multi-host computing system (100) running multiple operating systems is described herein. A file systems stored on different data partitions (110-1) and (110-1), of different operating systems (106-1) and (106-2), running on a multi-host computing system (100) may be shared based on file server-client architecture. According to the implementation, an operating system (106-1) may share its file system as file server and other operating system (106-2) may access the shared file system as file client. In one implementation, the sharing of data between multiple hosts is enabled by a dedicated high speed, low latency, inter processor communication bus, FiRE (124).

In certain embodiments, the score is determined solely from the URL string. Other embodiments include systems configured to perform such methods.

Abstract: Disclosed is a method for managing content on an information handling device, involving identifying creation of new content on the information handling device; tagging the content created on the information handling device with a unique identifier; and storing the unique identifier in a registry. When a risk to the information handling device is perceived, a plug-in on the device efficiently manages the content on the device.

Abstract: Mechanisms are provided for importing pre-existing data into a storage system utilizing a current storage management system that is different from an original storage management system used to create the pre-existing data. One or more data storage devices are integrated into the storage system in-place without modification of the pre-existing data stored on the one or more data storage devices. Metadata for the pre-existing data is created based on a linear progression of data in the pre-existing data. Read access requests targeting the pre-existing data are executed using the created metadata. Write access requests targeting the pre-existing data are executed by redirecting the write access requests to a copy of the pre-existing data created in another storage location.

Abstract: An input extension specification can be generated, via an administration tool on a business intelligence (BI) server, for an extender associated with a data warehouse in order to extend the data warehouse. The administration tool can request for data flow information of the data warehouse from the extender. The data flow information indicates the mapping relationship between one or more source data objects and one or more target tables in the data warehouse. The administration tool further allows a user to select said one or more target tables in the data warehouse to be extended based on the data flow information, and builds the input extension specification for the extender.

Abstract: A method for storing database information includes storing a table having data values in a column major order. The data values are stored in a list of blocks. The method also includes assigning a tuple sequence number (TSN) to each data value in each column of the table according to a sequence order in the table. The data values that correspond to each other across a plurality of columns of the table have equivalent TSNs. The method also includes assigning each data value to a partition based on a representation of the data value. The method also includes assigning a tuple map value to each data value. The tuple map value identifies the partition in which each data value is located.

Abstract: Methods and systems for use in validating input data in a computing system. Input data associated with a destination software application, such as a database, is received at a computing system. The input data is forwarded to an intermediate software application, such as a web application. When the input includes one or more patterns, a query produced by the intermediate software application based on the input data is validated, such as by comparing the structure of the query to one or more expected query structures. If the validation succeeds, the query is forwarded to the destination software application. Otherwise, the query is discarded.

Abstract: In general, a data synchronization management system is disclosed in which files (and/or other data) are synchronized among two or more client computing devices in connection with a backup of those files. Synchronization polices specify files to be synchronized based on selected criteria including file data, metadata, and location information. In general, files are initially copied from a primary client computing device to secondary storage. Thereafter, files to be synchronized are identified from the secondary storage, and copied to other client computing devices. Additionally, synchronized files may be viewed and accessed through a cloud and/or remote file access interface.
