10. January 30, 19985th TDML Conference9 Ease of Use & Design l Graphical User Interface –Objects with Properties l User Interaction –Events –Methods

11. January 30, 19985th TDML Conference10 Software Development l Visual Basic –Signal –MEDS l Visual C++ –Signal l Director –Lingo –Plug-Ins

12. January 30, 19985th TDML Conference11 Conclusions l Visual Basic –relatively easy to learn and use –not cross-platform –no easy WWW access (ActiveX) l VC++ –steep learning curve –cross-platform edition adds another level of complexity –no easy WWW access (ActiveX)

13. January 30, 19985th TDML Conference12 Conclusions l Director –Powerful with the use of Lingo & Plug-Ins –cross-platform (Mac/PC) –WWW access with Shockwave –Limited by built-in functionality l Other possible solutions: –Java –DHTML
