help with hash/database Can't Post
I can’t decide the best way to do this:
I need to build a database like this,
key = colors=>
color1 => red
color2 =>blue
color3 => black
ect…
key = shapes=>
shape1 => oval
shape2 => square
shape3 => circle
ect…
ect…

I need to search on key and return each item separately when called.
Would this be a multi dimensional hash? If so then would I have
to use MLDBM ? I’ve tried several different approaches with no luck
if this is something simple I apologize, but I just can’t get it.
also I need to stay with dbm files and away from mysql and the likes.

thanks
paul

Re: help with hash/database [In reply to] Can't Post
The only thing I know about such information is that you can use dbmopen() to tie an hash to a file, and dbmclose() to untie. When the hash is tied, it will contain the information located in the DMB file. Any change to the hash will automatically be changed in the file aswell.

Modern Perl however, mas more features like tie(), untie() and some modules. I haven't studied anything about tha, since I didn't need it recently. If anyone can answer this commen shared question of us, please do so.
