Comparação de Metodologias de Migração de Bancos de Dados Relacionais para Bancos Orientados a Documentos

Companies have migrated data from relational databases to NoSQLdatabases to improve their business through more active services ata lower operating cost, especially by the adoption of cloud services.This process is called Data Migration and is considered by someauthors one of the biggest challenges in systems engineering today.Although it is advantageous, the process of migrating data fromthe relational model to NoSQL models is not trivial and has led tothe development of different methodologies for this purpose. Theobjective of this work was to analyze and compare three differentmigration methodologies between Relational and NoSQL DocumentOriented databases under the following aspects: algorithminput, method documentation, migration process and generateddocuments. For that, different relational models were empiricallymigrated using such methodologies, allowing the analysis of theevaluated aspects. The results show that there is no consolidatedway to perform the migration and that the method to be chosendepends on the context of the application. So, scenarios that showwhen to use each method are presented. Although not performingcomputational tests, this work provides suggestions and insightsthrough the evaluation of the migration processes under the theoreticalmodels. It expected that the results presented here will helpIT managers decide on the best data model migration methodologyto follow in their actual projects.

Multi-Agent Active Services for Online Social Networks

This chapter has the goal of showing how multi-agent systems can be a suitable means for supporting the development and the composition of services in dynamic and complex environments. In particular, the chapter copes with the problem of developing services in the field of social networks. After an introduction on the relationships between multi-agent systems, services, and social networks, the chapter describes how multi-agent systems can support the interaction and the collaboration among the members of a social network through a set of active services.

The User as a Service

The Web has changed a lot since its inception, 20 years ago, now offering dynamic information and services. The users have also evolved and are no longer mere information consumers, but rather active producers. This calls for a paradigm shift, with the user at the center of the information, service, and collaboration networks, taking the role of active services (able to respond to requests), in equal terms with current service providers. This leads to a unified user model, in which both individual and institutional entities are users and providers, although with different emphasis. To support this approach, the authors present a new Web access device, the browserver, which includes a browser and a server working in close cooperation, with the goal of replacing the classical browser but being backwards compatible with it to ease the migration path. The authors show how it can be implemented and its advantages in the case of typical applications.

Developing Of Health Promotion Of District Hospitals In Thailand

The aim of this research is to investigate the health promotion services provided by district hospitals in the northeast of Thailand in order to improve health promotion guideline for district hospitals. The qualitative research was conducted from January 2009 to March 2010. Informants were the managers, the staff members responsible for developing and providing services of health promotion from 19 small, medium and large-sized district hospitals in the Northeastern region of Thailand. The in-depth interview was employed to gather the information analyzed by using content analysis. It was found that the new health promotion trends in district hospitals in the northeast were as follows. The organizational structures for promoting health were obviously defined while active services inside and outside the hospitals were clearly developed which bring health promotion practices to serviced users. Public policy for health was offered in the form of quality control, information management and active services while environmental management emphasized on creating comfort and learning environments for the hospital staff members and serviced users. Collaborations between professional organizations and multi-level networks had been established by district hospitals resulting in services with more accessibility and strengthening local communities. In addition, personal skill development and public health education yielded change to the health behaviors of hospital staff members, serviced users and people in local communities. For health service reorientation, there was emphasis on development of the quality of local community services in forms of professional standard development and assessment of health behavior outcome. The forms of health promotion provided by district hospitals in the northeast that were found were public policy for health promotion, active services, environmental management for health, community strengthening in form of collaboration networks, personal skill development and public health education for changing behavior, and change of health services. In order to improve health promotion, health promotion policies must be clearly defined and collaboration between stakeholders both inside and outside hospitals must be supported.

Active Service Using Acquaintance Nodes in Intelligent Manufacturing Environments

An active service architecture called AAS (active service based on acquaintances) for intelligent manufacturing environments was proposed. The proposed architecture exploits stable relation and resourceful nodes, called acquaintances, which perform active services in the manufacturing network. The AAS architecture recognizes node heterogeneity in terms of mobility and capability. We analyze the characteristics of AAS architecture and operations for optimal system performance. By showing that AAS outperforms broadcast-based solutions in manufacturing environments, we validate that AAS is a flexible and adaptable architecture appropriate for dynamic manufacturing environments.

A Co-Evolutionary Contract Net-Based Framework for Distributed Manufacturing Execution Systems

A manufacturing execution system (MES) is the information system of a process which actively collects processes and analyses the materials, semi-finished goods, finished goods, machine time, cost etc. on the production site in real time and monitors work in progress (WIP). In this work we present a service recommender system for active services according to service requestors’ goal in manufacturing execution system -workflows. The system is modeled as a multi-agent environment where clients and service agents negotiate using a Co-evolutionary Contract-Net (CeCN).It will improve the MES performance and capability and operating costs significantly.
