I want to put together a Web Site that aggregates niche text information.
I have to start somewhere so I am posting my initial questions here, in hope of some expert guidance and education.

I would like web site visitors to subscribe monthly to search the information.

So I have some questions.

Would I need a web host that provides a database?

What would be a fairly simple database application to use for this type of searching?

How can I import data and categorize it?

Is there a Search Site or Search Database application that you can recommend?

What else would you recommend?

Thanks. I look forward to your replies.
