The evolution of programming paradigms and languages allows us to manage the increasing complexity of systems. Furthermore, we have introduced (and demanded) increasingly complex requirements because various paradigms provide mechanisms to support their implementation. As a result, complex requirements constitute a driving factor for the evolution of languages which in turn can support system complexity. In this circular relationship, the maintenance phase of the software life cycle becomes increasingly important and factors which affect maintenance become vital. In this chapter we review the notions of software aging and discuss activities undertaken during maintenance. We also discuss challenges and trends for the development of well-maintained systems as well as for aiding in the maintenance of legacy systems.
