A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs translation of an abstract query into a form that can be used against a particular physical data representation.

A system for providing secondary data storage and recovery services for one or more networked host nodes includes a server application for facilitating data backup and recovery services; a first data storage medium accessible to the server application; a second data storage medium accessible to the server application; at least one client application for mapping write locations allocated by the first data storage medium to write locations represented in a logical view of the first data storage medium; and at least one machine instruction enabling direct read capability of the first data storage medium by the server application for purposes of subsequent time-based storage of the read data into the secondary data storage medium.

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.

The present invention is generally directed to a system, method and article of manufacture for accessing data represented abstractly through an abstraction model. In one embodiment, a data repository abstraction layer provides a logical view of an underlying data repository that is independent of the particular manner of data representation. A query abstraction layer is also provided and is based on the data repository abstraction layer. A runtime component performs conversion of an abstract query (i.e., a request for results or a request to modify data) into a form that can be used against a particular physical data representation. Abstract and / or physical queries are transformed according to model entities which define a relationship between logical fields of the data repository abstraction layer.

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.

A management display method according to each type of interfaces and devices is provided in an environment where host computers are interconnected with storage apparatuses through plural types of interfaces. The management host computer includes a display apparatus and allows a user to select a physical view for displaying a physical topology between each host and storage subsystems or a logical view for displaying a connecting relation between the devices of the storage subsystem and each host computer. The management host computer operates to collect the information of the Fibre channel interface and the Ethernet interface and the information about an access limitation of each device, included in each host computer and storage subsystem and then to display the connecting relation according to the display method (view) selected by the user, based on the collected information.

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.
