Análisis comparativo de patrones de diseño de software para el desarrollo de aplicaciones móviles de calidad: Una revisión sistemática de la literatura
En este artículo de revisión se realizó un estudio cuyo propósito es el de encontrar los principales estudios sobre patrones de diseño de software para el desarrollo de aplicaciones móviles de calidad, para posteriormente determinar criterios de identificación que servirán como herramienta de selección de patrones de diseño de calidad. Para este estudio se realizó una revisión sistemática de la literatura en 3 bases de datos reconocidas (IEEE, Explorer, EBSCO). De un total de 3072 artículos encontrados, se identificaron 16, que debido a su gran relevancia con el tema de estudio se seleccionaron para su posterior revisión. Se utilizó como instrumento principal la estrategia PICO para hacer la búsqueda y selección de los artículos de interés según el propósito de este estudio. Los resultados indican que son 5 los principales patrones de diseño de software para el desarrollo móvil de calidad y que existen ciertos criterios de identificación para su análisis. Se puede concluir que gracias a estos criterios de identificación podemos obtener una herramienta de selección para comparar los principales patrones de diseño de software para el desarrollo de aplicaciones móviles de calidad, y finalmente poder implementar la más conveniente según las necesidades del proyecto.Trabajo de investigaciónLIMAEscuela Profesional de Ingeniería de SistemasIngeniería de Softwar
SERVICE-BASED AUTOMATION OF SOFTWARE CONSTRUCTION ACTIVITIES
The reuse of software units, such as classes, components and services require professional
knowledge to be performed. Today a multiplicity of different software unit technologies,
supporting tools, and related activities used in reuse processes exist. Each of these relevant
reuse elements may also include a high number of variations and may differ in the level and
quality of necessary reuse knowledge. In such an environment of increasing variations and,
therefore, an increasing need for knowledge, software engineers must obtain such knowledge
to be able to perform software unit reuse activities. Today many different reuse activities exist
for a software unit. Some typical knowledge intensive activities are: transformation,
integration, and deployment. In addition to the problem of the amount of knowledge required
for such activities, other difficulties also exist. The global industrial environment makes it
challenging to identify sources of, and access to, knowledge. Typically, such sources (e.g.,
repositories) are made to search and retrieve information about software unitsand not about
the required reuse activity knowledge for a special unit. Additionally, the knowledge has to be
learned by inexperienced software engineers and, therefore, to be interpreted. This
interpretation may lead to variations in the reuse result and can differ from the estimated result
of the knowledge creator. This makes it difficult to exchange knowledge between software
engineers or global teams. Additionally, the reuse results of reuse activities have to be
repeatable and sustainable. In such a scenario, the knowledge about software reuse activities
has to be exchanged without the above mentioned problems by an inexperienced software
engineer. The literature shows a lack of techniques to store and subsequently distribute
relevant reuse activity knowledge among software engineers. The central aim of this thesis is
to enable inexperienced software engineers to use knowledge required to perform reuse
activities without experiencing the aforementioned problems. The reuse activities:
transformation, integration, and deployment, have been selected as the foundation for the
research. Based on the construction level of handling a software unit, these activities are
called Software Construction Activities (SCAcs) throughout the research. To achieve the aim,
specialised software construction activity models have been created and combined with an
abstract software unit model. As a result, different SCAc knowledge is described and
combined with different software unit artefacts needed by the SCAcs. Additionally, the
management (e.g., the execution of an SCAc) will be provided in a service-oriented
environment. Because of the focus on reuse activities, an approach which avoids changing the
knowledge level of software engineers and the abstraction view on software units and
activities, the object of the investigation differs from other approaches which aim to solve the
insufficient reuse activity knowledge problem. The research devised novel abstraction models
to describe SCAcs as knowledge models related to the relevant information of software units.
The models and the focused environment have been created using standard technologies. As a
result, these were realised easily in a real world environment. Softwareengineers were able to
perform single SCAcs without having previously acquired the necessary knowledge. The risk
of failing reuse decreases because single activities can be performed. The analysis of the
research results is based on a case study. An example of a reuse environmenthas been created
and tested in a case study to prove the operational capability of the approach. The main result
of the research is a proven concept enabling inexperienced software engineers to reuse
software units by reusing SCAcs. The research shows the reduction in time for reuse and a
decrease of learning effort is significant
