  This study was focused on the development of a web e-learning application for
the database courses taken by Information Technology (IT) students at the
College of Information and Communications Technology (CICT) of Bulacan State
University (BulSU). The research methodology used in this project was the
cross-sectional developmental approach. The Agile Software Development
methodology was followed phase by phase, up to the development phase, to
develop the system. It was used to produce the desired output rapidly while
allowing users to go back through phases without finishing the whole cycle. The
goal of this study was to create a web application that teaches Structured
Query Language (SQL) in both the MySQL and SQL Server approaches. The
application contains quizzes and examinations to allow self-assessment of
learning. Additionally, an Entity Relationship Diagram (ERD) simulation was
included to provide ERD creations in a drag-and-drop fashion. This study was
evaluated using ISO/IEC 25010 software quality evaluation criteria. The study's
overall mean was 4.24, 4.41, and 4.33, all with the descriptive meaning of
"Very Good," which showed that the system performed its necessary functions as
perceived by students, faculty members, and experts, respectively. In summary,
the e-learning web application for database courses was fully developed.
Moreover, the entity-relationship diagram was integrated well within the system
and is accessible to the users. Lastly, respondents evaluated the developed web
application using the ISO/IEC 25010 with an overall descriptive interpretation
of "Very Good." For future developments of the study, an administrator panel
may be developed to manage users and do other administrative tasks. Lastly,
higher-order thinking skills questions on assessments and quizzes may be
included.
