data flow analysis
Jump to user comments
programming A process to discover the dependencies between
different data items manipulated by a program. The order of
execution in a data driven language is determined solely by
the data dependencies. For example, given the equations
1. X = A + B
2. B = 2 + 2
3. A = 3 + 4
a data-flow analysis would find that 2 and 3 must be evaluated
before 1. Since there are no data dependencies between 2 and
3, they may be evaluated in any order, including in parallel.
