Abstract
Summary information for documents are stored as entries in a table in a relational database. Each entry includes a unique identifier, value(s) for a set of attributes and rendering information for the corresponding document. A collation order is obtained that defines a sort order for the documents based on the set of attributes. An index is generated based on the collation order and includes the rendering information for each document. In response to a rendering request or other query, a query that uses index-only access for the summary table can be used to obtain the rendering information. Further, a set of marker values can be included to provide efficient navigation of the index. Still further, additional functionality can be included to display the documents in a hierarchical structure. To this extent, the invention can automatically re-categorize data when the child locations of a hierarchical location exceed a specified number and/or link other relational data to a hierarchical location.
