Abstract: Database information may be accessed through a user interface comprising one or more interactive treemaps. Each interactive treemap reflects a hierarchical structure of the stored information, for example parent and child nodes. By providing one type of input (e.g., a reverse finger pinch) to a sub-area of the treemap, the user may cause a different treemap to be displayed reflecting the hierarchical structure (grandchild nodes) of the sub-area. A treemap may also be manipulated by a user to provide additional detail. For example, by providing another type of input (e.g., a finger tap) to a treemap sub-area, a user may cause further information relevant to a child node to be displayed as a pop-up or as a separate detail screen. The treemap views of the interface provide a user with fluid and intuitive navigation upward/downward through the hierarchy, with detail screens allowing access to additional stored database information as desired.
