gNova Inc. was founded in 2005 and closed in 2021. During that time gNova integrated its database products with the consulting services offered through O'Donnell Associates.

gNova Scientific Software created CHORD, a novel database cartridge that allowed you to easily create and quickly search relational databases containing many millions of chemical structures. 

gNova Consulting provided consulting and contract programming services to support scientific research and development. These included services related to the use and integration of CHORD, as well as many other types of scientific and web software.

O'Donnell Associates had been providing consulting and contract programming services since 1987.
