The term database here may be a bit confusing.  How 'bout we replace it
with dataset?
 
And to answer a part of the question that didn't really get answered,
DD is Data Definition.)   In the stream Nathan gives there's a line:
//X DD *
The // indicates this is a card with control language.  The X "names"
the dataset to follow.  DD says that this control card is a data definition.
The * says that the data follows this card directly and will end when a
/* (the last card in the example) is sent.
 
You may call me crazy (you won't be the first :-), but I *love* old OS
JCL... *sigh*  I miss it.  So clean.  So precise.
