— When we are developing a software system and we
know that it will suffer several changes, it is important to make it
adaptable, so that changes can be quickly performed with not so
much impact. One solution that has been used to develop
adaptable systems is the Adaptive Object Model (AOM)
Arquitectural Style, through which entities, properties,
relationships and behavior are represented as metadata and can
be changed by simply changing this metadata stored in a
database. However, developing systems with AOM may be
complex and its performance is questionable, especially when we
want most of the system to be adaptable. One way that has been
proposed to quickly develop AOM systems with a lot of reuse is
through the LOM (Living Object Model) framework. In this
work we show how a system can be developed using this
framework and we evaluate the performance overhead of making
most of a system adaptable with AOM using LOM. This
evaluation is performed through a case study using two versions
of a system to manage online exercises, which has been called
EducService.
