  abstract  = {It is common practice for requirements traceability research to consider
	method call dependencies within the source code (e.g., fan-in/fan-out
	analyses). However, current approaches largely ignore the role of
	data. The question this paper investigates is whether data dependencies
	have similar relationships to requirements as do call dependencies.
	For example, if two methods do not call one another, but do have
	access to the same data then is this information relevant? We formulated
	several research questions and validated them on three large software
	systems, covering about 120 KLOC. Our findings are that data relationships
	are roughly equally relevant to understanding the relationship to
	requirements traces than calling dependencies. However, most interestingly,
	our analyses show that data dependencies complement call dependencies.
	These findings have strong implications on all forms of code understanding,
	including trace capture, maintenance, and validation techniques (e.g.,
	information retrieval).},
