May 13, 1997 This fall's course will build on last year's course and on progress made since last year in the subject area of the course. The progress information comes from the literature, and our own research program (funded by NSF, DARPA and Xerox PARC). A new emphasis in the course will be on patterns and architectures for object-oriented software development. The new Demeter/Java system will be used which is a great tool to learn about many aspects of software development.
