Hi, new to mysql, php, designing a membership type of database,
potentially many members.
Essentially I am faced with a design choice;
have an oft run (modifiable) query run every time any user wants to
run it, comparing criteria againt each and every user in the table and
delviering list OR saving that list (user/user/) so the next time all
that needs to be queried is the existence of a record in the table.
The basic tradeoff; version 1 there are many simultaneous queries of
the user db on complex search criteria; version 2 there are fewer but
their are as many far more simple queries to a much larger table, not
to mention many writes to same to keep the table current.
I know this is pretty vague, but I was wondering if in general there
is an area that mysql excels in vis a vis complex query smaller tables
simple query larger tables.
Question 2 is there anyway to guestiate the search/write times of a
user log in to both query and update? #Records, fields, etc? I'd like
to keep log in to < 10 seconds max.
Thanks for any lite you can shed.
