Here is what my friend told me: Database sucks and MySQL too. Try program
without using database. Database is a file system. It is slow, take more
space...
But still there is many things I can not do with just simple text file, such
as updating a record....
I just found Tie:File which added many features to text files. Here is my
feature request to the owner of Perl: Add Perl Database, or at least
something called Perl Table
For instance in file:
symbol|price on day1|volume on day1|price on day2|price on day2|....
IBM|98.02|203092|97.01|1212300
SUNW|3.45|1112232|3.72|1212219
Let me select where symbel=IBM, or let me update price on day1 where
symbol=IBM to 99.08....
And things like that. I don't know much about SQL, so my SQl syntax maybe
wrong.
Any thought on my idea?
