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.
摘要翻译：提供了在更改资源成功完成的操作之前释放资源的技术。通过在操作本身已经成功完成之前提交执行部分操作的数据库事务来释放资源。如果操作无法成功完成，则使用“补偿信息”来消除作为操作一部分而执行的所作出的更改的影响。还提供了允许数据库事务更新值而不保留这些值的排他锁的技术。操作约束规定了允许进行更新之前必须满足的条件。如果尝试更新具有可以被撤销的变化的特定值，则数据库服务器确定特定值的多个“可能的结果值”。如果可能的结果值满足操作约束条件，则允许进行更新。

摘要： Systems, methods, and other embodiments associated with resource description framework (RDF) security are described. One example method includes generating, based on sensitivity labels associated with the contents of a triple in an RDF record, a sensitivity label. The example method may also include comparing the sensitivity label to an access label associated with an entity requesting an action associated with the record to be performed. The example method may also include performing the action upon determining that the entity has sufficient permission to request the action.

摘要： Systems, methods, and other embodiments associated with access control for graph data at the instance-level are described. One example method includes accepting data access constraints that are expressed as match and apply pattern pairs to enforce security policies. A user query on graph data with a security policy restricts the returned data to data that the user is authorized to access. For this purpose, a user query that includes query selection criteria corresponding to one or more match pattern criteria based on the resource referenced in the query is rewritten to include security conditions specified in the associated apply pattern to restrict access to the graph data.

摘要： A method for managing expressions includes receiving a first query that includes a first conditional expression. The first expression is then represented as data in a column of a table. A second query is received that specifies a first set of criteria, and the second query is executed to select data based at least on whether expressions in the column satisfy the first set of criteria. In an embodiment, the second query further specifies a second set of criteria, wherein executing the second query includes selecting data based on whether data in columns other than the expression column satisfy the second criteria. A special index is defined, which can be created on the column that stores the expressions as data, to filter large sets of expressions efficiently. A method of evaluating an expression set stored as data in a table classifies each predicate from each expression, and filters the expression set based on the predicate classification.

摘要： Disclosed are various embodiments for adjusting prices of items in foreign marketplaces based on fluctuations in currency exchange rates. A deviation from a return sought by a merchant for an item offered in an electronic marketplace is determined. The deviation results from a change in an exchange rate between a first currency employed by the merchant and a second currency employed by the electronic marketplace. It is determined whether the deviation from the return meets a threshold. One or more actions in response to the deviation are implemented when the deviation from the return meets the threshold.
