Resumen:
In this paper, we propose a compact data structure to store labeled at-
tributed graphs based on the k2-tree, which is a very compact data structure designed
to represent a simple directed graph. The idea we propose can be seen as an extension of
the k2-tree to support property graphs. In addition to the static approach, we also pro-
pose a dynamic version of the storage representation, which allows
exible schemas and
insertion or deletion of data. We provide an implementation of a basic set of operations,
which can be combined to form complex queries over these graphs with attributes. We
evaluate the performance of our proposal with existing graph database systems and
prove that our compact attributed graph representation obtains also competitive time
results.
