When trying to figure out the best way to implement a tree structure in a document database such as Couch or Mongo, several possibilities present themselves to me. Direct storage If your individual nodes aren’t very large and you can afford to load the whole thing in one call, storing it...
First, after in-depth analysis of MongoDB's features, we devise an efficient tabular document structure which flattens R-tree index into MongoDB collections. Further, relevant mechanisms of R-tree operations are issued, and then we discuss in detail how to integrate R-tree into MongoDB. ...
