Python is great for parsing data from wherever you get it and populating 
databases.  MySQL is ideal for the write-once-read-thereafter scenario 
that research implies.  You can use R for the initial data marshaling 
if you'd rather not learn another language but Python seems like a 
better fit for that sort of thing.  It's a scripting language that 
integrates more naturally into its host environment.  For analysis and 
visualization however, R absolutely rules.
