how large is 4 GB

Hi, All.

New to SQL. Just downloaded SQL server Express 2005, Web doc says its max limit is 4GB,

Need to know how large a 4GB can hold. The data shall be like holding company info, say: company names, locations, line of business, phone, etc. It needs full-text search on it.

Is this Express is the choice to go?

4 GB is a LOT. First of all, it's 4294967296 characters. But it's compressed in the database, so it's actually more.

My concern is, it is web based, once start running on web, it just might soon reach the limit. I've never done database before./(or serious programming for that matter.). So need to know a clue for a comparison. say, for an example, how many books of yellow-page-like data type that a 4 GB of MS SQL SERVER Express can hold?

Thanks

Honestly, you're worrying about nothing. Did you see how big the number was that I quoted ? It won't be an issue.

Really?

BTW 4GB is 4 gigabyte, which equal to 4 billion characters, if character set is one byte wide. If I go international, I need cut that number in half.

Yeah, I know that unicode is half that, but I didn't want to muddy the waters. If it's 4 billion exactly, that's not a real gigabyte. Whatever.

Either way, I still think you're worried over nothing. Use SQL Express, and if you run into trouble, migrate to SQL Server. Don't worry about stuff before you need to - 4 gig is a lot of data.
