Abstract: Systems, methods, and program products for federating a plurality of data sources using semantic data models are disclosed. A configuration ontology may be generated for each data source to identify how to access the data source. Generated metadata ontologies may be generated based upon extracted metadata to specify the data present at each data source. Domain ontologies may be generated for one or more target data environments that comprise a respective lexicon for specifying queries of the plurality of data sources. Bridge ontologies may be generated comprising electronic mappings between each data source and each domain ontology. For each data source that cannot be queried in place, a re-hosted data ontology may be generated by extracting the data and converting it to a corresponding triple data structure based upon the respective bridge ontology and the respective extracted metadata. Queries may then be directed to the plurality of data sources.

Abstract: A method of constructing a plurality of downloadable files from an application file and a plurality of transcripts. The application file stores data blocks and implements an application. Each of the transcripts stores at least one order in which at least a portion of the data blocks of the application file were accessed by the application when executed previously. The transcripts are combined into a combined transcript storing at least one combined order comprising a combined portion of the data blocks. The data blocks of the combined portion are arranged in a data structure having an origin. A first set of data blocks within a predetermined distance from the origin is stored in at least one initial execution file. A second set of data blocks outside the predetermined distance from the origin is stored in downloadable sequence files.

Abstract: A method and system for providing a connected sales associate service application via a mobile device. The application provides for an integrated platform upon which various tools for providing support to a sales associate are built. The application includes a database of information regarding the operation of a retail establishment, and a database of reference materials. The application provides a user interface for allowing several sales associate to access a central server for the retail establishment on multiple mobile devices. The user interface displays information regarding sales and inventory information and reference materials for products, such as user's manuals, which enable the sales associate to answer questions posed by customers. A sales associate can thus search for and find all store products which meet a customer's specifications.

Abstract: Methods, devices and systems enable restoring a database system more efficiently. A server computing device may be configured to determine a recovery time interval for a session store database system so as to allow a large number of sessions (e.g., ninety percent of sessions, etc.) to start and finish within that interval, periodically review database records to identify a database record that has not been updated within a most recent recovery time interval, add the identified database record to a journaling log, and update the identified database record to include information identifying a time at which the database record was last added to the journaling log. After detecting a failure event, the server computing device may perform the database operations identified in the journaling log to restore the database system.

Responsive to the indication, the requested copy is provided and is configured to reference the replica when the requested copy is accessed.

Abstract: Various methods and systems for monitoring files in a computer system are provided. In this regard, aspects of the invention facilitate file monitoring without file handle use, as it pertains to file monitoring and tailing, thereby mitigating file handle locking conflicts. In various implementations, information for the monitored files is obtained from the kernel using a filter driver in the I/O path. When the filter driver detects write operations being performed on monitored files, file-write data is copied and placed in a kernel buffer, where it can be pulled by a user mode monitoring process and fed to a monitoring application. As such, there is no need for coordination between the monitoring process and the user mode processes of other third-party applications writing data to monitored files.

Abstract: A system for modeling tabular data containing column and pivot table formats. Tabular data containing categorical and/or metric data is received and the metric data is determined. A group of identified columns are grouped comprising one or more adjacent columns containing similar metric data. Adjacent columns with unique metric types are not grouped. A number of columns (n) and rows (m) are identified. A table is generated comprising two sub-tables. A first sub-table is populated by metric data of ungrouped columns, repeated n times, containing ungrouped column category labels. A second sub-table with two columns, populated with grouped column category labels, repeated m times, and metric data from the grouped columns respectively. Category labels of the second table are determined via semantic analysis. The generated table, containing (n×m)+1 rows, is communicated to a model library.

Abstract: Techniques for analyzing and synthesizing complex knowledge representations (KRs) may utilize an atomic knowledge representation model including both an elemental data structure and knowledge processing rules stored as machine-readable data and/or programming instructions. One or more of the knowledge processing rules may be applied to analyze an input complex KR to deconstruct its complex concepts and/or concept relationships to elemental concepts and/or concept relationships to be included in the elemental data structure. One or more of the knowledge processing rules may be applied to synthesize an output complex KR from the stored elemental data structure in accordance with an input context. Multiple input complex KRs of various types may be analyzed and deconstructed to populate the elemental data structure, and input complex KRs may be transformed through the elemental data structure to output complex KRs of different types, providing semantic interoperability to KRs of different types and/or KR models.

Abstract: The present invention provides a system and method for sending a cellular text message to a system server through a data network, including an identification of a requested database record and a forward address. The system server then performs a database lookup or related search and sends an enhanced message or a file to the forward address, which could be a cellular phone, e-mail address, server, computer, mobile device, or any hardware or device associated with the intended recipient that is communicatively coupled to the system server.

Abstract: The subject matter described herein relates to managing data with flexible schema. A method, computer storage medium, and system are provided for managing data with flexible schema. In one embodiment, the method comprises providing a logical view for logical tables of a database; and managing mappings between the logical tables and a physical table according to predefined mapping constraints, each of the logical tables mapped as a part of the physical table. The mapping constraints at least specify that (i) a logical column in the logical tables is mapped to at least one physical column in the physical table, and (ii) distinct logical columns in one of the logical tables are mapped to distinct physical columns in the physical table. As a result, schema evolution may be done with minimized data migration.

Abstract: A title standardization system is may be configured to detect an edit operation associated with the job title field of a member profile stored by an on-line social network system and, in response, perform operations to derive a canonical title that represents a raw title string found in the job title field. The derived canonical title may be then associated with the member profile, in which the originally-obtained subject title string was found. This association may be stored in a database for future use, e.g., for targeting job recommendations, recruiting, making professional contacts, as well as for other purposes.
