Database logical design and physical implementation
		are always first priority, but beyond our scope here.
	Application partitioning
	Work close to the data - actually inside the database is best
	Stored procedures
			many benefits where they are applicable
			language often painfully limited compared with Perl
	Moving data is expensive -bandwidth (bulk) and latency (iterations)
	Bulk-load - use proprietary tools for maximum speed
		- you can use perl to massage the data into the right form
		- bulk-load tools often have limited functionality
		use DBI for maximum flexibility, such as update-else-insert
