Sparksee (formerly known as DEX) is a high-performance and scalable graph database management system written in C++.

Its development started in 2006 and its first version was available on Q3 - 2008. The fourth version is available since Q3-2010. There is a free community version, for academic or evaluation purposes, available to download, limited to 1 million nodes, no limit on edges.

Sparksee is a product originated by the research carried out at DAMA-UPC (Data Management group at the Polytechnic University of Catalonia). On March 2010 a spin-off called Sparsity-Technologies has been created at the UPC to commercialize and give services to the technologies developed at DAMA-UPC.

DEX changed name to Sparksee on its 5th release on February 2014.

Graph Model [1]

DEX is based on a graph database model,[2] that is basically characterized by three properties: data structures are graphs or any other structure similar to a graph; data manipulation and queries are based on graph-oriented operations; and there are data constraints to guarantee the integrity of the data and its relationships.

A DEX graph is a Labeled Directed Attributed Multigraph. Labeled because nodes and edges in a graph belong to types. Directed because it supports directed edges as well as undirected. Attributed because both nodes and edges may have attributes and Multigraph meaning that there may be multiple edges between the same nodes even if they are from the same edge type.

One of its main characteristics is its performance storage and retrieval for large graphs (in the order of billions of nodes, edges and attributes) implemented with specialized structures.
