摘要： Techniques are provided for extending a business transaction framework to support user-provided compensation logic for business transactions. The extensibility framework may be used to implement user-defined semantics for (a) validating concurrent updates to shared data and (b) performing compensating actions when an associated transaction is aborted. In one embodiment, the extensibility and the compensation are provided at the data-type level. User-provided logic also maintains summaries that include values that are externalized so that they may be referenced in user-provided operational constraints.

摘要： A metadata-driven merchant feed processing system is described herein. A merchant providing an online marketplace for the sale of items by a variety of sellers implements a feed processing mechanism driven by feed metadata. The feed metadata consists of declarative metadata statements that model the semantics for transforming seller-facing feed data describing the seller's items to customer-facing listings data to be loaded to an item catalog. The feed metadata captures differences between different versions of the item catalog by maintaining the semantics of the product categories and attributes of the item catalog as of a certain version. Similarly, semantics in the feed metadata modeling new product categories and/or attributes are utilized to support supplemental feeds from sellers to support new features and improvements in the item catalog. The metadata driven feed processing system also provides support for multiple types of seller-facing data entities and feed formats through metadata mapping.

摘要： A method and apparatus for introducing domain-specific data types with associated semantics in an RDF database system using an extensibility framework mechanism. The extensibility framework mechanism allows users to map serialized instance data for a particular user-defined data type to properties of a base data structure associated with the domain-specific data and to map instance data in base data structures to the data's serialized form. The RDF database system may return inferred properties of RDF data stored in domain-specific data types in response to a query on the data. Further, the RDF database system may infer relationships between resources in stored data.

摘要： Techniques are provided for freeing up resources before operations that change the resources have successfully completed. Resources are freed up by committing database transactions that perform portions of operations before the operations themselves have successfully completed. If the operations fail to complete successfully, then “compensation information” is used to remove the effects of the committed changes that were performed as part of the operation. Techniques are also provided for allowing database transactions to update values without retaining exclusive locks on those values. Operational constraints set forth conditions that must be satisfied before an update is allowed to proceed. If an attempt is made to update a particular value that has changes that may be undone, then the database server determines a plurality of “possible result values” for the particular value. If the possible result values satisfy the operational constraint conditions, then the update is allowed to proceed.

摘要： A method and apparatus for proactive information security management is described. In one embodiment, for example, a computer-implemented method for controlling access to sensitive information, the method comprising: maintaining access constraint data that can be used to control access to the sensitive information, wherein the access constraint data includes match pattern data and apply pattern data; receiving a semantic query from a querier requesting access to the sensitive information; based on the match pattern data, determining whether the semantic query should be constrained according to the apply pattern data; where said semantic query should be constrained according to the apply pattern data, rewriting the semantic query according to the apply pattern data to produce a rewritten query; executing the rewritten query against a database that contains the sensitive information; and returning any results of executing the rewritten query.

摘要： First data that represents a level associated with an element within an expression, such as an XPath expression, is generated from the expression, and stored in one or more columns of a table. Second data that represents a condition on an attribute of the element is generated from the expression, and stored in one or more columns of the same or a different table. A plurality of expressions can be processed as such, and a determination made whether any of the expressions match with a given hierarchical data item, such as an XML document, that includes a value that corresponds to an attribute that is associated with an element that resides at a particular level within the data item. Such determination is made based on whether the particular level matches the first data and the value satisfies the second data associated with a given expression.

摘要： Systems, methods, and other embodiments associated with row level security for a database table are described. One example method includes detecting an access statement seeking access to a row in a database table for which row level security is active. The method includes adding a predicate to the access statement. The predicate is based on an access control expression associated with the row. The access control expression depends on an instance of an expression data type associated with the row. The method includes populating an attribute of the predicate, and controlling access to the row based on a computed value for the predicate.

摘要： A mapping mechanism for a primary B+tree in a database management system. The primary B+tree includes a plurality of rows. The mapping mechanism includes introducing a mapping table that includes a plurality of rows, including a row for each row of the primary B+tree, and that stores the logical identifier of the corresponding primary B+tree row. In addition, reverse mapping is provided by augmenting a primary B+tree to include in each primary B+tree row a physical row identifier of the corresponding mapping table row. An auxiliary structure created on a primary B+tree can make use of the proposed mapping mechanism. Specifically, the auxiliary structures refers to primary B+tree rows indirectly by storing the physical row identifier of the corresponding mapping table row.
