Abstract: A method and system for entities of a data access layer, the data access layer following an entity-relationship model in which data are depicted in term of entities and relationships between them and the entities are provided with a CRUD interface. The method includes the steps of: defining a meta-entity being a virtual entity, resulting as a composition of parts of one or more entities; describing the virtual entity, via a virtual entity descriptor, as a hierarchical structure in which entities are connected in a parent-child structure via a link; in the virtual entity descriptor, specifying which properties are taken from each entity to form partial entities of the virtual entity; providing a CRUD interface on the virtual entity; and at run time, accessing the virtual entity via its CRUD interface. The accessing is implemented as a set of calls to CRUD methods accessing the entities composing the virtual entity.

Abstract: A data de-duplication method begins by a processing module receiving a plurality of data storage requests from a plurality of requesting devices wherein a data storage request includes the data and a requester identifier (ID). The method continues with the processing module obtaining a data identifier (ID) for the data. For each of the plurality of data storage requests, the method continues with the processing module producing a requester storage record, dispersed storage error encoding the requester storage record to produce a set of encoded requester storage record slices, and sending the set of encoded requester storage record slices to a dispersed storage network (DSN) memory for storage therein. The method continues with the processing module dispersed storage error encoding at least a portion of the data to produce a set of encoded data slices and sending the set of encoded data slices to the DSN memory for storage therein.

Abstract: A computer that is programmed with software attaches one object (“from-object”) to another object (“to-object”) by preparing a new duplicate of certain metadata in the from-object, without copying any content of the from-object. The new duplicate metadata is stored in memory for use in identifying the from-object and the to-object as being attached. If the from-object itself has any existing attachments, e.g. to a group of additional objects, there already exists a group of existing metadatas that form existing attachments between the from-object and the group of additional objects. In such a case, the computer still prepares, without content copying, a group of new metadatas to identify the relationship between a corresponding additional object and the from-object. Some embodiments also identify the to-object within each metadata in the group of new metadatas, thereby to identify a path of objects through which an additional object is accessible.

Abstract: The present invention provides techniques for managing a multi-tenant database system. In one embodiment the method includes providing access to data stored in a multi-tenant data structure that is implemented by storing data for multiple tenants on a pool of computer servers defining the multi-tenant data structure that having a plurality of data columns and one or more index columns. The one or more index columns define a first data field for a first tenant of the multi-tenant data structure and a second data field for a second tenant of the multi-tenant data structure. The first field indicates a first data type and the second field indicates a second data type, wherein the second data type is different than the first data type. Once created, records having data values in the first and second fields are stored to a single column in the data structure. The single column includes data values having different data types for different tenants in the multi-tenant data structure.

Abstract: Systems and methods enabling search of a repository for the location of data that is similar to input data, using a defined measure of similarity, in a time that is independent of the size of the repository and linear in a size of the input data, and a space that is proportional to a small fraction of the size of the repository. Additionally, remote operations are accomplished with significantly reduced system bandwidth by implementing remote differencing operations.

Abstract: An information-processing apparatus includes a networking device that communicates with an external apparatus. The information-processing apparatus also includes a storage that stores an album of a plurality of content data and a transfer log indicating whether each of the content data has been transferred to the external apparatus. The information-processing apparatus additionally includes a processing unit that identifies certain content data from the content data of the album when the transfer log indicates that the certain content data has never been transferred to the external apparatus and controls a display of information about the album. Further, the processing unit starts a transfer of the certain content data to the external apparatus, when the album has been selected and the certain content data has never been transferred to the external apparatus, and updates the transfer log when the networking device transfers the certain content data to the external apparatus.

Abstract: A method for retrieving data in a data source is provided. The method includes receiving a search term; identifying an active tag associated with the search term; correlating the active tag to dynamic data that is operative to adapt to a mining context in which data is stored; and retrieving the data using the dynamic data.

Abstract: Information hierarchies are efficiently stored and accessed in a relational or object-relational database system. A path signature, similar to a pathname, is stored in a database system in association with data for the node identified by the pathname. For example, a path signature identifying an element is stored in a row that holds data for the element. To retrieve data for a hierarchical query that identifies the data requested using, for example, an XPATH string, a string pattern is generated that is matched by path signatures identified by the XPATH string. Pattern matching is then used to select rows associated with matching path signatures, and data from the selected rows is used to compute the XPATH query. Furthermore, hash values representing path signatures are generated in a way that preserves the ordering of data in an information hierarchy. The hash values can be indexed to provide quick access.

Abstract: The invention provides a system and method for retrieving documents from a collection of documents that match a word search query. A word index is generated for each document in which each entry is an enriched-term string built from the stemmed form of the word to be searched and a separator character followed by the original form of the word to be searched. During a retrieving operation, a search query is processed depending the original form or the stemmed form of a word to be searched. Cross-documents tables are addressed to find documents that match the enriched-term string of the word to be searched.

Abstract: A coordinate system is assigned to an object in a group of objects (e.g. an image in a digital photo album or a page in a document). The object is rendered on a display. A value correlated to the coordinate system is transmitted when another object in the group of objects is to be viewed. From this value, another related object (e.g. the next image in the album or the next page in the document) is identified and transmitted. This related object is then rendered on the display in place of the first object.

Abstract: At least one quasi-identifier attribute of a plurality of ranked attributes is selected for use in anonymizing a database. Each of the ranked attributes is ranked according to that attribute's effect on a database-centric application (DCA) being tested. In an embodiment, the selected quasi-identifier attribute(s) has the least effect on the DCA. The database is anonymized based on the selected quasi-identifier attribute(s) to provide a partially-anonymized database, which may then be provided to a testing entity for use in testing the DCA. In an embodiment, during execution of the DCA, instances of database queries are captured and analyzed to identify a plurality of attributes from the database and, for each such attribute identified, the effect of the attribute on the DCA is quantified. In this manner, databases can be selectively anonymized in order to balance the requirements of data privacy against the utility of the data for testing purposes.

Abstract: A recommendation system may use a network of relationships between many different entities to find search results and establish a relevance value for the search results. The relevance value may be calculated by analyzing trust and similarity components of each relationship between the search user and the entity providing the search results. The entities may be, for example, persons associated within express or implied social networks, or corporations or other organizations with a historical or other reputation. The relationships may be created through many different contact mechanisms and may be unidirectional, asymmetric bidirectional, or symmetric bidirectional relationships. The relationships may be different based on topic or other factors.
