    • A method, system and article of manufacture for protecting sensitive data in databases and, more particularly, for managing access to sensitive data in a database. One embodiment comprises receiving a query against the data in the database comprising at least (i) a result field specification, and (ii) a sorting instruction. The method further comprises retrieving a result set from the database, and filtering the retrieved result set on the basis of predefined filtering rules to remove selected data from a selected result field of at least one data record included with the retrieved result set. The filtered result set is sorted according to the sorting instruction to produce the sorted result set, whereby the sorting is done independently of the removed selected data so that the sorted result set places the at least one data record at a position which is non-indicative of a value of the removed selected data.
    • 一种用于保护数据库中敏感数据的方法,系统和制品,更具体地说,用于管理对数据库中的敏感数据的访问。 一个实施例包括接收关于数据库中的数据的查询,其包括至少(i)结果字段规范和(ii)排序指令。 该方法还包括从数据库检索结果集,并且基于预定义的过滤规则对检索的结果集进行过滤,以从包含在检索结果集中的至少一个数据记录的选定结果字段中移除所选数据。 根据分类指令对滤波后的结果集进行排序,以产生排序结果集,由此排序独立于所移除的所选数据进行,使得分类结果集将至少一个数据记录放置在非指示位置 的已删除选定数据的值。

    • A method, system, and article of manufacture to process database queries are disclosed. One embodiment comprises receiving an abstract query against a database having a multiplicity of data records. The abstract query identifies a model entity that defines a focus of the abstract query. The method further comprises receiving a limitation request configured to restrict a result set for the abstract query. The limitation request specifies a limitation on data records that are returned for one or more instances of the underlying model entity. From the abstract query, an executable query capable of being executed by a query engine is generated. The executable query is modified on the basis of the limitation request. The modified executable query is executed against the database to obtain the result set, whereby the result set is restricted as requested by the limitation request.
    • 公开了一种处理数据库查询的方法,系统和制品。 一个实施例包括针对具有多个数据记录的数据库接收抽象查询。 抽象查询标识定义抽象查询焦点的模型实体。 该方法还包括接收被配置为限制抽象查询的结果集的限制请求。 限制请求指定对基础模型实体的一个或多个实例返回的数据记录的限制。 从抽象查询,生成能够被查询引擎执行的可执行查询。 可执行查询根据限制请求进行修改。 针对数据库执行修改的可执行查询以获得结果集,由此限制请求的请求限制结果集。
