How can I detect that a file was added then display a message to the share, then save the filename and username to a database in a  table that I create ? What are the steps ?

Based on this question you asked about how to fetch data from a database via JavaScript, I'm going to assume you figured this out. Looks like you chose to use a Behavior, which is a good approach, but, as I noted in my response, you really ought to write to a separate database and stay out of Alfresco's schema.
