    • 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 for managing relationships between database tables and, more particularly, for identifying and accurately describing relationships between tables in a database. One embodiment provides a method for identifying relationships between tables in a database. The method comprises receiving user input selecting a plurality of tables from the database. The plurality of tables is organized into a logical island defining a logical unit related to a particular logical entity. The method further comprises receiving user input identifying, for each of the plurality of tables, a table column containing information that identifies the particular logical entity in the table, whereby the identified table columns of different tables define logical relationships between the different tables in the logical island. On the basis of the identified table columns, relations specifications are created which describe the logical relationships between the different tables in the logical island.
    • 一种用于管理数据库表之间的关系的方法,系统和制品,更具体地,用于识别和准确描述数据库中的表之间的关系。 一个实施例提供了一种用于识别数据库中的表之间的关系的方法。 该方法包括接收从数据库中选择多个表的用户输入。 多个表被组织成定义与特定逻辑实体相关的逻辑单元的逻辑岛。 所述方法还包括接收用户输入,对于所述多个表中的每一个,识别包含标识所述表中的特定逻辑实体的信息的表列,由此所标识的不同表的表列定义逻辑中不同表之间的逻辑关系 岛。 在识别的表列的基础上,创建了描述逻辑岛中的不同表之间的逻辑关系的关系规范。
