Ítem Aspectos claves en la definición y adopción de estándares de interoperabilidad electrónica de datos : El caso de HL7 en el área de la salud(Universidad Icesi, 2008-12-18) Tamura Morimitsu, Gabriel; Villegas Machado, Norha MilenaThis article presents the results of the analysis that the DRISO research group has conducted about some aspects which have been found as critical in the process of definition and adoption of standards for exchange of electronic data, in the context of the HL7 standard for interoperability in health. For each considered aspect, its potential contribution to a standard for semantic interoperability is identified, as well as how it is used in the modeling of the objects to exchange, and in the modeling of the exchange process itself. The analysis of the critical aspects of standards is done following the line of the evolution of HL7 standard, identifying and distinguishing their structural and dynamic aspects. Finally, as a matter of conclusion, a reflection about the applicability of this analysis to the Colombian Ministry of Communications GEL-XML project, for electronic data exchange of basic data in all sectors of the economy.Ítem Análisis descriptivo del proceso de implementación del nivel 2 del modelo CMMI en una empresa regional de desarrollo de software(Universidad Icesi, 2008-12-18) Picazzo M., Catherine; Villegas Machado, Norha Milena; Tamura Morimitsu, GabrielCMMI (Capability Maturity Model Integration) is basically a continuous- improvement inspired model to classify software development organizations according to a fivelevel maturity and capability scale. The classification in a given level is based on the dominance that an organization shows evidence to have over the areas of that level, which in turn reflects the degree of maturity of the organization and of the processes that it follows to develop software. This article presents a preliminary descriptive analysis of a level 2 implementation process of the CMMI model in a Colombian software development company, making an overall presentation of how it was brought into practice the theory of the model in the processes of the company, to be compliant with the conditions, goals and practices defined in the level 2 process areas of the model. The article also describes the problems which arose in the execution of the project, as well as how they were solved. As preliminary results are presented some of the indicators defined by the company for the software processes, and the software tools that were acquired or developed for the support of the implementation of the process areas. Finally, some conclusions and recommendations which can be found.Ítem Development and instrumentation of a framework for the generation and management of self-adaptive enterprise applications(Pontificia Universidad Javeriana, 2016-01-01) Arboleda Jiménez, Hugo FernandoCompanies’ operations have become over-dependent on their supporting enterprise software applications. This situation has placed a heavy burden onto software maintenance teams who are expected to keep these applications up and running optimally in varying execution conditions. However, this high human intervention drives up the overall costs of software ownership. In addition, the current dynamic nature of enterprise applications constitutes challenges with respect to their architectural design and development, and the guarantee of the agreed quality requirements at runtime. Efficiently and effectively achieving the adaptation of enterprise applications requires an autonomic solution. In this paper, we present SHIFT, a framework that provides (i) facilities and mechanisms for managing self-adaptive enterprise applications using an autonomic infrastructure, and (ii) automated derivation of self-adaptive enterprise applications and their respective monitoring infrastructure. Along with the framework, our work led us to propose a reference specification and architectural design for implementing self-adaptation autonomic infrastructures. We developed a reference implementation of SHIFT; our contribution includes the development of monitoring infrastructures, and dynamic adaptation planning and automated derivation strategies. SHIFT, along with its autonomic infrastructure and derived enterprise application, can provide a cost-effective mean to fulfill the agreed quality in these types of applications. © 2016, Pontificia Universidad Javeriana.
