TECHNOLOGY TRENDS and FUTURE NEEDS (CK) - 1

• Object-Orientation (OO) (1 of 2)
• New and old in the same time
• Still a hard to implement paradigm
• Even its inventor (B. Stroustrup) doubts its real
  capabilities for large scale, complex systems
  development (check his Web site)
• Requires long curve learning and hands-on
  training
• Language support (read C) its challenging
• Better, pure OO programming languages, did not
  catch with the industry (Smalltalk, Eiffel,
  Modula 2, even Ada or Object Pascal!)

TECHNOLOGY TRENDS and FUTURE NEEDS (CK) - 2

• Object-Orientation (OO) (2 of 2)
• Many people take VB as an OO language (!?)
• Java may help - if Microsoft wants so...
• Component-based Architecture (1 of 2)
• Even though jurys out on OO
• A software component is a program element with
  the following properties
• It may be used by other program elements, or
  clients.
• The clients and their authors do not need to be
  known to the components authors. - B. Meyer

TECHNOLOGY TRENDS and FUTURE NEEDS (CK) - 6

• Network-centered, Client/Server, and Web
  Architecture (1 of 2)
• Less and less applications are stand-alone,
  static, or in batch processing mode
• Client/Server
• the architecture of early 90s
• jurys still out on cost/benefits/affordability
• tolls and technology support
• Web architectures
• the emergence of e-commerce and e-transactions
• Intranets and Extranets are everywhere

TECHNOLOGY TRENDS and FUTURE NEEDS (CK) - 7

• Network-centered, Client/Server, and Web
  Architecture (2 of 2)
• no other way of doing business, for the
  foreseeable future
• BSIS - MSIT bridge (1 of 1)
• MSIT in question for now
• Link with ISYS 324/327
• Programming Skills, Top Computer Literacy,
  Technology Savvy all key elements, especially
  for first couple of MSIT proposed courses
• Questions, Comments, Suggestions?
