writing hash to a file ...is it possible

perlplayer has asked for the wisdom of the Perl Monks concerning the following question:

hello i have a user data file all data of a single user in a single line delimited with '|' Now I am able to split the data and create dynamic hash of hashes from the data . i am working with this hash through out the script but its taking long time to finish as the users are many
My Question 1: Is there a better way to do it such that the run time will be less.
My Question 2: I want to store each user data as a hash in a file like we can store a whole structure in a file in C Lang. In perl is it possible to write that way.

I recommend you use DBM::Deep. Once loaded, it can work just like a hash and is fast.	[reply]

"My Question 2: I want to store each user data as a hash in a file like we can store a whole structure in a file in C Lang. In perl is it possible to write that way." Perhaps Storable is what you are looking for if you want to reopen these files later within a Perl script. Martin	[reply]

Q1: Access to a hash of hashes is fast, perhaps your use of the hash of hashes could be speeded up. Q2: a text based solution could be: `use Data::Dumper;` to write out and eval the contents to "reload" what has been written out.	[reply] [d/l]
