I am developing a database/web-based db interface for what could potentially be a gargantuan amount of data. I have been developing in ASP using a MS Access database. I have started to become familiar with mySQL databases and have started to think for speed and efficiency issues that I should use a mySQL database instead of an Access one. Ive done some preliminary research but I want to know what you guys think I should do. A main reason I'm using an Access database is because the people I'm developing for know how to use its query options because its GUI-based and pretty straight forward. Any suggestions?
