Not related to 764 .



U.S. skill base in decline:

•Drop in enrollments

(and drop in female enrollments:

1985 .. 50% , 2006 .. 5% )

•Retirements

•Cut in foreign visa H-1B visas

http://en.wikipedia.org/wiki/H-1B_visa

but (?) many job ads are “fake”:

“Our goal is clearly not to find a qualified and interested U.S. worker.”

Question:

Is 764 a DB Design course?

Why / how?

Not ?



Question:


Object-relational mapping:

puts the “DB” design at the “object-design” level

puts queries at the object-query level (or EJB-query)

Good software engineering:

puts analysis and design at the object (UML) level

(not ER level, not table level)



Question:


Missing: tuning, …



Relation of ~ DB courses:

app-DB-SE (764) --------- DB theory (761)

web (726) DM (864)

(?? Tuning, DBA support, very large DBs )
