Have you been involved with the improvement of a company's existing data architecture? If so, explain your role in the process and the impact the change had on the company overall.

"In my experience, marrying external data with internal data within corporate systems can bring about possible issues of data integrity. I initiated a project where I developed a process that carefully screened our 3rd-party purchased data using several detailed steps. I also established a close relationship with our data supplier who agreed to run several checks on the data before sending it over to us. This increased our data reliability and reduced database errors by 34% over a span of a year."
