No, you don't need a database to run webeditor2009. Some CMS systems cut existing web pages into HTML snippets to fit the database requirements. We think CMS software has to adapt to an existing webpage and not the other way round. You can edit your existing web pages as is.
I'm not a computer expert. Can I install WebEditor2009 myself?
