Database Technology
Whether it's a client server or a web-based application, today
it's likely there's a back-end database involved. And not just Access or some
other single user database. High-end relational databases like Microsoft's Sql
Server, Informix, Oracle, and others are being used to manage today's
high-volume business transactions.
The software engineers of today need more than just a casual
understanding of SQL. I've had the opportunity over the past 10+ years to use
several of the high-end, RDMS solutions available today. My experience includes
not only database design and query optimization, but also the use of such 3rd
party add-ons as "Crystal Reports".
