Abstract:
Databases are an important modern society component and the knowledge
in this area
is
valuable for the information technology professional. It is possible
to obtain this knowledge
through
the database course, mandatory in several computer science curricula.
In the course,
it
is addressed data modeling and database design. The students perform
activities related to
a
given data modeling problem, and to do so, they use academic and/or
commercial CASE
tools.
However, among the academic tools, there is not a tool which allows
the data modeling
diagramming
and is available on the web. As a solution, it was developed Coloph,
a database
learning
CASE tools prototype available on the Web, focusing on the
conceptual, logical and
physical
modeling. A bibliographic review in the topics of databases, data
modeling, CASE
tools
and distance education was performed. Based on that, the prototype
requirements were
gathered.
Subsequently, the prototype was applied to a case study, involving
two groups: students and teachers from a database course. As a data
gathering technique, surveys based on the
TAM
(Technology Acceptance Model) methodology were used, in order to
verify the prototype
acceptance
among students and teacher. After the data analysis, it was verified
that prototype
had
a positive reception and acceptance among the students and teacher,
especially regarding to
its
availability on the Web.
