Abstract: The present invention extends to methods, systems, and computer program products for virtualizing objects within queries. Embodiments of the invention virtualize data access for use with queries. Virtualization can be implemented within any portion of a syntax tree. For example, data can be virtualized for a property of an object that is itself another object. Data virtualization facilitates lazy evaluation of query expressions. That is, actual property values for properties within a data construction statement are virtualized until a query specifically requests the actual property values. Further, data virtualization also conserves resources and results in more efficient query evaluations.

Abstract: A system for retrieving stored data and/or index pages, receives a database request, generates an access plan for the database request for accessing data rows and/or index entries according to the statement, and generates a priming process by selecting a set of data and/or index pages. The set of data and/or index pages is a super-set or the exact set of the pages needed for accessing data rows and/or index entries according to the access plan. The present system retrieves the data and/or index pages of the set before executing the database request according to the access plan. The execution of the database request is performed by scanning the index and data pages preloaded into the cache. This reduces the number of necessary disk reads during execution.

Abstract: Methods and apparatus, including computer program products, implement techniques for processing experimental data in a laboratory data management system. An input specifies a set of variable definitions that define a set of variables for an experiment type to be represented by a pre-defined experiment class. The variables in the set of variables have types selected from a predefined set of data types. Data from an experiment of the experiment type is received. A first representation of the data is stored in a format defined according to the set of variable types. A second representation of the data, derived from the first representation, is presented in a format defined according to the set of variable definitions.

Abstract: A system and method facilitating a unified framework for accessing structured and unstructured data is provided. The invention includes a source document having data that is parsed into a data document component providing a hierarchical representation of data associated with the source document and a data set component providing a relational representation of at least a portion of the data associated with the source document. The invention further provides for a schema defining a structure of the relational representation to be associated with the source document and/or inferred by the data set component. Data stored in the data document component and the data set component are synchronized, thus a change made to data stored in the data set component is reflected in data stored in the data document component. Further, a change made to data stored in the data document component is reflected in data stored in the data set component if utilized according to the schema.

Abstract: The present invention provides “XML Schema Collections” and methods and systems for using the same. XML data is typically stored as an XML instance, each of which should conform to a “schema” according to a desired goal. An XML schema provides identification and organization for the data supplied by an XML instance. XML Schema Collections are collections of one or more XML schema namespaces. A storage location designated for storage of XML data, such as an XML column in a relational database, can be “typed” with an XML Schema Collection object, allowing that storage location to store XML instances that conform to more than one XML schema. XML Schema Collections provide increased data storage versatility, and facilitation of data searches.

Abstract: The disclosed embodiments provide rapid access to information stored on a personal computing device even though the personal computing device is powered off or otherwise in a low-power consumption state such as a sleep state or hibernation state. An software component gathers user data in a location such as a non-volatile memory associated with a host computer. A browser component accesses the stored data and makes it available to the user when the host computer is powered down or otherwise in a state of low power consumption.

Abstract: A system of query scheduling to maximize work sharing. The system schedules queries to account for future queries possessing a sharability component. Included in the system are operations for assigning an incoming query to a query queue based on a sharability characteristic of the incoming query, and evaluating a priority function for each member of a plurality of query queues to identify one highest priority query queue. The priority function accounts for the probability that a future incoming query will contain the sharability characteristic common to a member of the plurality of query queues. The system of query scheduling to maximize work sharing selects a batch of queries from the highest priority query queue, and dispatches the batch to one or more query execution units.

The selected content is related with a package corresponding to the data stored in the filtering data file.

Abstract: Systems and methods are disclosed for providing access to a thumbnail image that is embedded within an image file along with a corresponding main image. An exemplary method involves receiving a request from a client for the thumbnail image. The thumbnail image is retrieved from an image host. The entire image file is not retrieved from the image host. The thumbnail image may be sent to the client. Alternatively, the thumbnail location information may be sent to the client. Retrieving the thumbnail image from the image host may involve identifying a location of the thumbnail image within the image file, and retrieving data from the image file corresponding to the location.

Abstract: A computer-implemented system (10) for associating target data with a product classification schema includes a data association module (39) that accesses the product classification schema. The schema includes a taxonomy that includes a hierarchy of classes into which products may be categorized. The schema further includes ontologies that are associated with one or more of the classes. Each ontology includes one or more product attributes. The data association module (39) accesses the target data to be associated with the schema and determines one or more classes with which at least a portion of the target data should be associated. This determination is based on a comparison between the target data and the product attributes of the ontologies or between the target data and values for one or more of the product attributes.

Abstract: Embodiments of the invention provide methods, apparatus, and articles of manufacture for providing security architecture for content management systems. An audit log table separates security concerns in framework code from application concerns in application code. Application developers place database access code in stored procedures. Each stored procedure records a unique identifier for each object involved in the database access code into an audit log, for later security checking by framework code. After executing the stored procedure, the framework code determines whether the stored procedure was authorized by checking the audit log and access control lists stored in the database. If not, an access violation error may be returned and the database may be rolled back.

Abstract: A client computer system of a cluster may send a request to create a file in a cluster file system. A server may create a file in response to the information and allocate space in a storage to the file. If a request to write to the file is received within a predetermined amount of time, the write may complete without requiring that additional operations be performed to allocate space to the file. If a write to the file is not received within the predetermined amount of time, the space allocated to the file when it was created may be de-allocated. The file system may additionally or alternatively perform a method for opening a file while delaying an associated truncation of space allocated to the file. If a request to write to the file is received within a predetermined amount of time, the write may be performed in the space already allocated to the file.

Abstract: A relationship and navigation data repository can interface with a central data model and contains templates that define relationships among data from a number of distributed heterogeneous data sources. An integration engine is coupled to the relationship and navigation data repository, and can receive a query command and determine which of the heterogeneous data sources and which of the templates the query applies to, and then calculate the desired query result, responsive to the command, based on the relevant data sources and templates. The distributed heterogeneous data sources are managed by a system and method that involves obtaining pre-existing definitional data, instantiating in-memory nodes for the data, initializing a relationship attribute and an entity attribute for each of the nodes, and then forming an updated navigation tree structure therefrom.
