Concrete Data Structure
(CDS) A model of programming language terms developed in the context of
constructing fully abstract semantics for sequential languages. A CDS is a
4tuple (C,V,E,) where C is a cell, V is a value, E is an event and  is an
"enabling relation". An event is a cell and a value. A cell C is "enabled" by a
set of events S if S  C. A state is a set of events which are consistent in
that the values they give for any cell are all equal. Every cell in a state is
enabled.
