In fact, demand for tighter integration between ChEMBL and these tools was one of the outcomes of our recent Workflows workshop . Indeed, using the web services via a workflow tool is a seamless way to search, retrieve, integrate and analyse data without having to install, maintain and update local databases or write, dreaded for some, SQL queries.
