Project Overview

The pgchem::tigress project was started in 2004 and aims to develop a complete solution for handling chemical data in a relational database management system, based 100% on open source components.

While pgchem::tigress fully integrates into PostgreSQL it also is an extensible toolbox for developing your own solutions and should be portable to other RDBMS.

As of version 7.x, substructure search performance is acceptable for databases up to 1 million structures on an Athlon64 3000+ or better, but performance improvement is an ongoing process.

Notable features not found in current commercial products are the perception of functional groups and the ability to choose between different screening and matching techniques.

Pgchem::tigress contains no secrets or closed components, offering a unique insight how chemical database systems work.

Development was initially funded by the Science & Technology department of Bayer Business Services GmbH and is currently continued by Ernst-Georg Schmid.
