A method for logical view visualization of user behavior in a networked computer environment that includes sites that a user may visit and wherein the sites comprise pages that the user may view and / or resources that the user may request includes the step of collecting raw data representing user behavior which can include requesting resources, viewing pages and visiting sites by the user. This raw data is then refined or pre-processed into page views and visit data and stored in a data mart. Pages are clustered into super pages, and page to super page mappings reflecting the relationship between pages and super pages are stored in the data mart. An automated clustering means is applied to the page view, visit and super page data in the data mart to discover clusters of visits to define super visits having visit behavior characteristics. The visit data stored in the data mart is then scored against the super visit clusters to classify visits into super visits according to visit behavior characteristics. A system is also provided.

Systems, methods, and computer program products for synchronizing items at replicas within a topology is disclosed. Items are stored in physical tables at the replicas. The physical table layouts at each replica can differ but are mapped to a common logical view. When a replica receives an indication that synchronization should be performed, the replica determines if changes have been made at the replica that should be mapped to the logical views. Replicas can facilitate this by comparing local change enumerations for changes made in physical tables to synchronization local change enumerations for changes in the logical views. Any changes that need to be synchronized are sent through the logical views to other replicas in the topology.

The method of managing contents on a network in which a server and at least one client device are connected to one another, includes operations of the server comprising; receiving a content list request from one of the at least one client device; and providing one of physical view information and at least one type of logical view information having information on the contents which can be provided by the at least one client device to a client device which transmits the content list request.

Virtual links may be used to divert traffic within an Ethernet network without affecting overall traffic patterns on the Ethernet network. In one embodiment, the virtual link may be established on the network via a routing system in use on the network. Nodes on a defined path for the virtual link will install forwarding state for the virtual link so that traffic may follow the defined path through the network. The logical view of the virtual link, from a routing perspective however, has the same cost as the shortest path between the endpoints of the virtual link and, accordingly, does not affect other traffic patterns on the network. Once established, the end nodes on the virtual path will have two equal cost paths through the network—one following the shortest path tree and one along the path for the virtual link. The end nodes may use a tie breaking process in an Equal Cost Multi Path (ECMP) selection process to preferentially select the virtual link over the shortest path.

Systems and methods are disclosed for providing a federated backup involving the coordination and synchronization of backup and restore operations among a plurality of hosts to ensure data consistency. A master node (backup host) acts as the initiator, coordinator, controller, and possibly as primary console for the entire backup and restore operation. All other worker application hosts and / or worker backup hosts operate as worker nodes and perform various backup and restore steps as directed by the master node. Centralized error handling aborts or recovers the entire backup operation in the event of failure on any one node. In addition, a logical view of the data is provided such that the backup can be managed as one entity, while backing up the data of each node. The backup workload may also be distributed to any other dedicated worker backup hosts (nodes) in order to minimize the impact to the production environment.

Various methods and systems for presenting a logical view of a database backup are disclosed. One method involves querying a database recovery manager for logical identifiers that correspond to physical backup pieces generated during a backup. The method uses the logical identifiers to display a backup view to a user. The backup view identifies logical database components that are available to be restored.

The invention provides a configuration tool to allow a user to build a custom-selected data object hierarchy, for business intelligence or other purposes. Under conventional data storage technologies, the physical layout of the disk drive or other media has dictated what logical views and searches a user could run on the underlying data. For instance, levels could not be readily skipped or many-to-many data object relationships were difficult to maintain. In the invention, a user may select and connect a set of data objects into a hierarchy of their choosing, to permit desired reports and other manipulations on the data to be performed. The hierarchy may be edited, and entry points may be defined. Different levels of security may be applied to the different levels of the hierarchy. Multiple hierarchies or representations may be built for one database or other data source.

The virtual jukebox may be coupled with the host by way of the host system bus, or a network coupled with the host. In an alternative embodiment, the virtual jukebox is implemented as a standalone unit.

Embodiments of the present invention generally provide methods systems and articles of manufacture for query processing and for constructing a database abstraction model over an underlying physical database. The database abstraction model allows users to compose an abstract query using a logical view of data, instead of using the view of the underlying database architecture. Embodiments of the invention constrain the results returned from processing an abstract query according to relationships that exist for a group of logical fields. First, a group of logical fields may be related because they are part of a logical set. Field-to-field join constraints specify the logical fields that form a set, and an instance indicator used to determine the particular instance of a set that an element of data belongs to, according to a discrimination rule. Second, logical fields may be related because they are part of a series, and an instance identifier may provide an ordering rule used to determine the order of data elements that form the series.

A unified query building system generates a source structure comprising nodes from a data structure input of an identified data source, displays the generated source structure in a logical view, adds a selected node or element from the nodes to a design query canvas, generates a query object from the selected node based on a source type of the selected node, presents a logical view of a query function of a selected query object, and generates a unified query comprising the generated query objects. The logical view is displayed in a graphical user interface comprising a design query canvas comprising grids corresponding to functions in a query language such as SQL or XML. The generated unified query is displayed in an actual query view and is outlined in a query outline view.
