    • 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, apparatus, and article of manufacture for managing access to an abstract database are provided. The abstract database may include a data abstraction model comprising a plurality of logical field definitions, each of the definitions comprising a logical field name, and an access method maps the logical field to a physical data field. Collectively, the physical data fields provide an indirection layer logically disposed between the data abstraction model and the underlying physical database. By providing this layer of indirection using the physical data fields, a number of enhancements to the data abstraction model may be provided. This includes providing enhancements to the security, administration, and usability of an abstract database.
    • 提供了一种用于管理对抽象数据库的访问的方法,装置和制品。 抽象数据库可以包括包括多个逻辑字段定义的数据抽象模型,每个定义包括逻辑字段名称,并且访问方法将逻辑字段映射到物理数据字段。 总体而言,物理数据字段提供了逻辑上位于数据抽象模型和底层物理数据库之间的间接层。 通过使用物理数据字段提供这种间接层,可以提供对数据抽象模型的许多增强。 这包括提供抽象数据库的安全性,管理和可用性的增强功能。
