implementation of Chitra95, a software system
developed for the visualization and analysis of
time-series trace data. Chitra95 is based upon
two earlier generations of Chitra and is aimed at
producing a system with broad applicability and
utility in this area of research.
This thesis contributes to the area of software
design for trace visualization and analysis by
proposing a set of design principles towards
achieving the goals of system extensibility,
reusability, reliability, testability and verifiability.
These design principles are demonstrated by
Chitra95, a software architecture proposed in
this thesis for visualization and analysis of
time-series trace data. This architecture is novel
in its combination of independence from
problem domain semantics; optimization for
user-extensibility and code reusability; freedom
from any specific user interface model; ability to
simultaneously produce an integrated
application and a reusable toolkit of parts that
may either be customized into a turnkey system
or integrated into other software systems;
support for enhanced reliability, testability and
verifiability; and support for an interface to the
World Wide Web and for remote execution.
Finally, this thesis makes the specific
contribution of a data structure for representing
large traces that permits the maintainance of
multiple versions of a trace and retains the
ability to undo modifications made to a trace.
