Abstract

See full text

A method for traversing hierarchical data is provided. The method may include generating, based on a source table stored in a database, an index for traversing a graph corresponding to the source table. The source table may identify a parent node for each node in the graph. The generating of the index may include iterating over the source table to generate an inner node map. The inner node map may include at least one mapping identifying one or more children nodes descending from an inner node in the graph. The graph may be traversed based at least on the index. The index may enable the graph to be traversed depth first starting from a root node of the graph and continuing to a first child node descending from the root node of the graph. Related systems and articles of manufacture, including computer program products, are also provided.
