[try again]

I have heard that Access Databases are not great when used in high volume
situations. 

I plan to use an Access dbase for logins which would only be accessed for
members but I also want a lookup table to resolve directory names
according to a page / category code passed. 

Can anyone tell me if there is any disadvantage in holding this lookup
table as a csv file. This would be constantly read by practically every
visitor who visits the content pages. I hoped to avoid constant opening of
the database but this may be a false economy if the same applies to text
files as it does to Access.

Any help in understanding the issues would be greatly apreciated.

regards

Louis
