Similar Projects, Different Computer Language 
The first high-level languages of the late 1950s and 1960s such as FORTRAN
and COBOL were both flexible and portable in that they could be used for many
kinds of computer applications and they could make programs for many different
kinds of computer. By the late 1980s, some computer languages had more specific
purposes, but these languages were almost as flexible.
For
instance in 1991, two divisions of the University of Pennsylvania were using dBase
III, an advanced database programming language for two radically different tasks.
The Student Health Service was using dBase III to manage student health records,
requiring excellent information retrieval capability. The University Museum was
creating a database of Middle Paleolithic excavation sites to determine where
archeologists should dig. Both applications were written in dBase III, but the
Museum's project required the compilation and analysis of graphical and textual
criteria, whereas the Student Health Service was working with large amounts of
complex textual information. One language was able to create two different applications
whose only common factor was a need for powerful databases. Another
Museum application, COMPASS, developed at the Museum Applied Science Center for
Archeology (MASCA) relied upon a Pascal related language to map and analyze archeological
sites on MacIntosh computers. This project had conceptual parallels to the application
that required dBase III. Yet the two projects utilized two very different computer
languages. |
