Conditional access to data

A database system may include records, each record including a set of attributes. The database system may also include database views, each representing a subset of the set of attributes. A subset of attributes indicating a set of attributes and a destination object of processing destination data may be stored. Each processing destination may be associated with one or more entities authorized to access a subset of processing destination attributes. A request for data for a particular processing purpose and a selected one of the database views may be received. Objects indicative of particular processing destination data may be retrieved. A subset of attributes represented by the selected view may be compared to a subset of attributes indicated in the retrieved data destination object. Values for a subset of attributes of the selected view may be provided. 数据库系统可以包括记录，每个记录包括一组属性。数据库系统还可包括数据库视图，每个数据库视图表示属性集的子集。可以存储指示属性集合的属性子集和处理目的数据目的对象。每个处理目的可以与被授权访问处理目的属性子集的一个或多个实体相关联。可以接收对用于特定处理目的的数据的请求和所述数据库视图中的所选视图。可以检索指示特定
