Storing site content in a mySQL database
I have been told that storing my web content in a mySQL database and serving it from there would be an immense waste of resources. Is this true? Would the speed of my site be hurt by it? Would it eat up all of my server's resources if I had a lot of hits every day? My idea was to store content in a mySQL database and use PHP pages that would read their content from the dB. This would save me from having redundant data and the content would then be searchable within the dB. Is this a bad idea?
