    Within the analysis and development of software, it has been considered a fundamental aspect the implementation of standards that allow us to implement, design and integrate different elements for an application to meet or be framed within different characteristics. The requirements of users have become over time in real challenges to be met by software developers and has sought the need to lower costs with the goal of mass production of content. For this reason, that has been penetrated in new technologies that handle this type of paradigms with the objective of optimizing the necessary resources for the implementation of technological projects, we have found tools such as Integranova, WebRatio, Genexus, that have adopted the paradigm or part of it, offering an agile development alternative in an increasingly competitive market. The objective of the present research is to analyze and to make a comparative between two tools based on a Model-Driven paradigm and to determine which of the two is more convenient for the use by the characteristics that it possesses, as well as by that well it complies the parameters to be considered a Model-Based tool. In the present study the comparison between two tools will be carried out in a given scenario, through the same one it is proposed to analyze the advantages and disadvantages that each tool has in the development of the different requirements of the initial problem. It will evaluate the versatility of the tool and the facilities that they present to the users for their correct implementation and likewise will evaluate the capacity of assimilation of the tool as the basis of a factor of productivity applied to a real field. There will be different regulations to satisfy based on the definition of the model Entity-Relationship, services, transactions, roles and user permissions, etc. We will evaluate how these requirements are handled in both tools, as well as the final product obtained with each of them.Dentro del análisis y desarrollo de software, se ha considerado un aspecto fundamental la implementación de estándares que nos permitan implementar, diseñar e integrar diferentes elementos para que una aplicación cumpla o se encuentre enmarcada dentro de diferentes características. Los requerimientos de los usuarios se han convertido con el pasar del tiempo en verdaderos retos a cumplir por parte de los desarrolladores de software y se ha buscado la necesidad de abaratar costos con el objetivo de masificar la producción de contenidos. Es por esta razón, que se ha incursionado en nuevas tecnologías que manejan este tipo de paradigmas con el objetivo de optimizar los recursos necesarios para implementación de proyectos tecnológicos, se han encontrado herramientas como Integranova, WebRatio, Genexus¿, que han adoptado el paradigma o parte de él, ofreciendo una alternativa de desarrollo ágil en un mercado cada vez más competitivo. El objetivo de la presente trabajo es analizar y realizar una comparativa entre dos herramientas basadas en un paradigma model-driven y determinar cuál de las dos es más conveniente para su uso por las características que posea, así como también por que tan bien cumpla los parámetros para ser considerada una herramienta basada en modelos. En el presente estudio se realizará la comparativa entre dos herramientas en un escenario determinado, mediante el mismo se plantea analizar las ventajas y desventajas que posee cada herramienta en el desarrollo de los diferentes requisitos del problema inicial. Se evaluará la versatilidad de la herramienta y las facilidades que presentan a los usuarios para su correcta implementación y de igual manera se evaluará la capacidad de asimilación de la herramienta como la base de un factor de productividad aplicada a un campo real. Habrá diferentes normativas que satisfacer partiendo de la definición del modelo entidad ¿ relación, servicios, transacciones, roles y permisos de usuario, etc. Se evaluarán como se manejan estos requisitos en ambas herramientas, así como el producto final obtenido con cada una de ellas.Pineda Álvarez, DF.

    A semantic framework for unified cloud service search, recommendation, retrieval and management

    Cloud computing (CC) is a revolutionary paradigm of consuming Information and Communication Technology (ICT) services. However, while trying to find the optimal services, many users often feel confused due to the inadequacy of service information description. Although some efforts are made in the semantic modelling, retrieval and recommendation of cloud services, existing practices would only work effectively for certain restricted scenarios to deal for example with basic and non-interactive service specifications. In the meantime, various service management tasks are usually performed individually for diverse cloud resources for distinct service providers. This results into significant decreased effectiveness and efficiency for task implementation. Fundamentally, it is due to the lack of a generic service management interface which enables a unified service access and manipulation regardless of the providers or resource types.To address the above issues, the thesis proposes a semantic-driven framework, which integrates two main novel specification approaches, known as agility-oriented and fuzziness-embedded cloud service semantic specifications, and cloud service access and manipulation request operation specifications. These consequently enable comprehensive service specification by capturing the in-depth cloud concept details and their interactions, even across multiple service categories and abstraction levels. Utilising the specifications as CC knowledge foundation, a unified service recommendation and management platform is implemented. Based on considerable experiment data collected on real-world cloud services, the approaches demonstrate distinguished effectiveness in service search, retrieval and recommendation tasks whilst the platform shows outstanding performance for a wide range of service access, management and interaction tasks. Furthermore, the framework includes two sets of innovative specification processing algorithms specifically designed to serve advanced CC tasks: while the fuzzy rating and ontology evolution algorithms establish a manner of collaborative cloud service specification, the service orchestration reasoning algorithms reveal a promising means of dynamic service compositions

    Una aproximación dirigida por modelos para la caracterización de la capa de presentación web de aplicaciones empresariales

    Actualmente, UML es la notación de diseño más ampliamente usada en el diseño y desarrollo de software orientado a objetos. Sin embargo, UML estándar no es suficiente para caracterizar la capa de presentación Web de las aplicaciones empresariales. La comunidad de la Ingeniería Web ha proporcionado el concepto de mapa navegacional para tratar de gestionar la complejidad inherente a las aplicaciones Web. Siguiendo este concepto, hemos desarrollado NMMp, una notación de diseño que, como las notaciones de la Ingeniería Web, proporciona una visión abstracta de la estructura navegacional dela capa de presentación Web. Sin embargo, a diferencia de estas, promueve la inclusión explícita de todo el catálogo de patrones arquitectónicos y de diseño en los modelos, los cuales, son ampliamente usados en el sector industrial.Sin embargo, NMMp no tiene en cuenta la caracterización de frameworks específicos usados ampliamente en el desarrollo de la capa de presentación Web de aplicaciones empresariales modernas. Generalmente, estos frameworks soportan el desarrollo de la navegación, la estructura de presentación y el control de acceso basado en roles (RBAC),características presentes en la mayoría de este tipo de aplicaciones. Siguiendo la filosofíade NMMp, hemos desarrollado el enfoque Enterprise Web Application Extensión (EWAE),como un conjunto de extensiones UML que soportan el modelado de estas características presentes en frameworks específicos..

    Model-Driven Design and Development of Semantic Web Service Applications

    This paper proposes a model-driven methodology to design and develop semantic Web service applications and their components, described according to the emerging WSMO standard. In particular, we show that business processes and Web engineering models have sufficient expressive power to support the semi-automatic extraction of semantic descriptions (i.e., WSMO ontologies, goals, Web services, and mediators), thus partially hiding the complexity of dealing with semantics. Our method is based on existing models for the specification of business processes (BPMN) combined with Web engineering models for designing and developing semantically rich Web applications (WebML). The proposed approach leads from an abstract view of the business needs to a concrete implementation of the application, by means of several design steps; high level models are transformed into software components. Our framework increases the efficiency of the whole design process, yielding to the construction of semantic Web service applications spanning over several enterprises
