Abstract: Various technologies and techniques improve the updating of client content in a client/server arrangement. A client notification engine of a user interface subscribes to receive notifications from a central server side notification engine. The client notification engine polls the server side notification engine at a specified interval. The server side notification engine receives and aggregates notifications about and/or from one or more sources and aggregates them into a collection of relevant notifications. These notifications are sent to the client where the different subscriptions originated and are then used by the user interface in the client to update part of the content being displayed as appropriate.

Abstract: Images created by one or more image acquisition devices are initially stored in remote data bases at one or more remote or satellite locations and copies of the images are subsequently transferred to a central server at a central storage location over a network and stored in a central data base. A common catalog listing local image files stored at the central data base and remote image files stored at one or more remote data bases is stored at the central location and is accessed by users to search for images. User requests for images associated with local image files result in transfer of the requested images by the central server to the user. User requests for images associated with remote image files are relayed by the central server to the associated remote location, and the requested images are then relayed to the user from the remote location via the central server.

Abstract: A cluster of computer system nodes share direct read/write access to storage devices via a storage area network using a cluster filesystem. Version information about subsystems is acquired by a leader node when forming a cluster membership and distributed to all nodes in the cluster to enable proper messaging during operation.

Abstract: A system and method for distributed query processing may compile and optimize query plans for incoming query requests independent of hardware configurations and/or physical locations of data partitions in a distributed storage system (e.g., a data grid). The query plan may be divided into segments, and each segment may be instantiated on a remote query processing node of the distributed system by a query coordinator node according to metadata accessed at runtime by remote sub-query operators in the query plan. The metadata may include an indication of the physical locations of data partitions in the system and may be stored on one or more of the query processing nodes. The remote query processing nodes may execute the query plan segments and return results to the requestor. Cached query plans may be re-executed without recompilation, according to current metadata, even in the event of a node failure or data partition move.

Abstract: In a method for controlling access from a first network component to at least one second network component, a unique user identification for a user of the first network component is calculated by the first network component. A request created by the first network component on the basis of an order is transmitted with the unique user identification to the second network component. A rights checking instruction is created by the second network component on the basis of the unique user identification. The rights checking instruction is transmitted by the second network component to the first network component. Access for the user to the second network component is provisioned by the second network component when a transmitted result of a check indicates that the user is authorized for access to the second network component.

Abstract: Client node caching in a global file service. A client node receives a leaf image from a remote storage node storing a base image that is read-only accessible to the client node. The leaf image has a portion of the base image modified by the client node. The client node stores the leaf image in a cache on the client node. Unmodified portions of the base image are accessed from the remote storage node. Modified portions of the base image are accessed from the cache. The leaf images may comprise a branch modification log having portions of the base image modified by the client node and a metadata structure. The metadata structure has pointers to the modified data in the branch modification log and pointers to data unmodified by the client node in the base image. Alternatively, the leaf images may comprise a change volume for changes made to the base image by the client node.

Abstract: The invention comprises a set of complementary techniques that dramatically improve enterprise search and navigation results. The core of the invention is an expertise or knowledge index, called UseRank that tracks the behavior of website visitors. The expertise-index is designed to focus on the four key discoveries of enterprise attributes: Subject Authority, Work Patterns, Content Freshness, and Group Know-how. The invention produces useful, timely, cross-application, expertise-based search and navigation results. In contrast, traditional Information Retrieval technologies such as inverted index, NLP, or taxonomy tackle the same problem with an opposite set of attributes than what the enterprise needs: Content Population, Word Patterns, Content Existence, and Statistical Trends. Overall, the invention emcompasses Baynote Search—a enhancement over existing IR searches, Baynote Guide—a set of community-driven navigations, and Baynote Insights—aggregated views of visitor interests and trends and content gaps.

In one embodiment, the method includes moving, during a first scan, outgoing records from a sending partition to one or more receiving partitions, where free space is created in the sending partition due to the outgoing records leaving the sending partition. The method also includes filling, during the first scan, some of the free space with remaining records that do not leave the sending partition.

Abstract: A database communication system is described herein that structures communications in a way that provides lower overhead tracking, statistics, semantics for closing a communication, and reliability. The system provides communication namespaces that organize communications by component, purpose, and instance, which allow database servers to implicitly create communication-related objects without central coordination. The database communication system enables group-based communications that streamline the development of complex distributed components and protocols by providing creation and management of communications namespaces, centralized cleanup support, and centralized monitoring. These features allow the system to be highly distributed, with no one single coordinator of operations, and still provide reliable communications. Thus, the system allows databases to be spread across multiple servers while keeping the burden on database server developers of managing communications between the servers low.

Abstract: The present invention extends to methods, systems, and computer program products for accessing and manipulating data in a data flow graph. A data flow graph includes one more transforms for transforming data from one or more data stores into different formats accessible to clients. Transforms can be configured to join and split data from the same or different data stores. A metadata tree logically represents the data flow graph including locations that provide output from transforms of the data flow graph. The locations can be referenced by clients to access transformed outputs. Clients can register dependencies on data at various locations and can request evaluation of the data in response to data changes at a corresponding data store. Clients can also request data changes be propagated back through the data flow graph to one or more data stores and implemented at the one or more data stores.
