Concept analysis transforms any relation between ``objects'' and ``attributes'' into a complete lattice. This concept lattice can be studied by algebraic means and offers remarkable insight into properties and structure of the original relation. As relations between ``objects'' and ``attributes'' occur all the time in software technology, concept analysis is an attractive foundation for a new class of program analysis tools. The article presents applications of concept lattices for the modularizqtion of legacy code, understanding configurations spaces, and transformations of class hierarchies.
