I was hoping someone on this list could help me understand the primary

because packages
o break the dependency chain (no cascading invalidations when you
install a new package body -- if you have procedures that call
procedures -- compiling one will invalidate your database)
o support encapsulation -- I will be allowed to write MODULAR, easy to
understand code -- rather then MONOLITHIC, non-understandable procedures
o increase my namespace measurably. package names have to be unique in a
schema, but I can have many procedures across packages with the same
name without colliding
o support overloading
o support session variables when you need them
o promote overall good coding techniques, stuff that lets you write code
that is modular, understandable, logically grouped together....
