RDBMS

[St-Cyr]

Sorry, maybe not a lot. Hmm let's say exchanges about how easy a change in the SEIV app was or not. Seen, hrmm... read some about this.

What's a relational database?

In life: Oracle, MS-SQL, DB2, Sybase, MySQL, Access, etc

In science: mostly symply 3 rules which are called the 3 normal forms as defined by Cobb + add meta-data to it.

Those are real easy to find on the web so I won't enumerate them here. I'll just preach for my own:

Very simplified, it's a way to solve validation and assertion problems in a multi-user setting while the data is coming IN and not when it's going OUT.

I've seen/helped it solve excruciating logical and/or performance problems. A mouse click that used to take 45 seconds now takes the animation time to depress it; a night job that needed full cpu for 8 hours now runs in 5 minutes during rush-hour; etc.
