Search engine/login pages

Hi,

I am a beginner in web design and i just need some basic info on how to get started with search engines. If i am using dreamweaver how would i start a website. For example if i am coding my words with html and flash, do i have to also link everything somewhere else like in access and then code it in something else? Where does access and sql come to play with this. Is there some type of step by step book i can get to help me understand better. I guess i am confused as to once i have this info stored somewhere how to make the search engine with dreamweaver, would it be actionscript?
