                 vital to an organisation




Nitin V Pujari           B.E– CS - Software Engineering – Legacy Systems   Slide 1
Objectives
                 To explain what is meant by a legacy system and why these systems
                 are important
                 To introduce common legacy system structures
                 To briefly describe function-oriented design
                 To explain how the value of legacy systems can be assessed
