Hello Everyone, I am starting a project for the company antivirus software installed. The company size is around 250 seats. Small environment. As I know, I can go for Microsoft SQL Express or MySql for the database. SQL Express has a 10GB size limited. For the small environment, is it work out? how much the database size will be reached? I don't want to reach the DB size limitation in one day and stop the service. Thanks GK
