Abstract:
Elepaño et al. has successfully accomplished all features and functional requirements
necessary for the development of VirHoLex. However, the system was not thoroughly tested
after each module was integrated, generating a number of system bugs as a result. Though
Morales has partially refactored VirHoLex, specifically the Virho References and Virho
Hotspots modules, the modifications done were not sufficed to make the codes maintainable.
In order to preserve the credibility of the system, Struts framework was incorporated
into the program structure of VirHoLex after the system was debugged. Struts is built on
MVC design pattern that promotes separation of concerns, that is, separating business logic
from the user's view. The whole VirHoLex was refactored a) to remove jumbled and
redundant codes; b) to make the codes reusable and modular; and c) to promote programming
style uniformity for all modules. This will allow the future developers to easily understand
and modify the system.
In addition, the use of Subversion and Mantis Bug Tracking tool is pertinent to the
study since it permits the developers to easily track down the history of file changes, and to
have a proper documentation of system bugs and new features respectively. More
importantly, the second version of VirHoLex was deployed on MaxPlanck server so that
virologists can fully utilize the system.
