ABSTRACT:
Hierarchical data may be provided. First, first data may be received corresponding to a first item. The first item may correspond, for example, to a web site. Next, a first cache may be created corresponding to an ancestry of the first item. In creating the first cache, information may be included configured to define a hierarchy of the first item. The first item may correspond to a child web site and the information in the cache may correspond to a plurality of parent web sites higher in the hierarchy and being related to the child web site. The first cache may include the plurality of parent web sites in a parent-relative fashion. Then, the received first data corresponding to the first item may be stored in a database. In addition, the first cache may be stored in the database as a property of the stored first item.
