My Bulletin on Cogito — i.e., a short-short white paper — is now available for download. Thankfully, it turned out to be pretty consistent with what I previously wrote on the company and its technology. The conclusion to the paper bears quoting here:
In deciding between conventional DBMS and specialty graph-oriented tools such as Cogito’s, there’s one key criterion: Path length. If path lengths are short and predictable, there’s a good chance that relational DBMS and their forthcoming extensions can do the job. In complex graphs with longer paths, however, relational approaches may not scale well. In such cases, specialty technologies warrant serious consideration.
