Title: Support for Enterprise Applications in SOFA 2 Author: Tibor Blénessy Department: Department of Distributed and Dependable Systems Supervisor of the master thesis: RNDr. Tomáš Bureš, Ph.D. Abstract: Industry standards defining various aspects of enterprise systems were developed in order to make development of such systems faster and to increase interoperability. For systems created with Java platform, these standards are contained under Java Enterprise Edition. SOFA 2 component system provides a solid base for development of ex- tensive component oriented systems. Goal of this work is to propose and empirically verify the possibility of integration of existing industry standards for enterprise applications in SOFA 2. Proposed solution extends SOFA 2 with components for web user in- terfaces based on Java Servlet API standard and with components for persisting data into relational databases based on Java Peristence API. In addition, it integrates core technologies from the Java Enterprise Edition platform, which should make integration of further standards easier. Keywords: enteprise applications, component system, SOFA 2, Java EE

A Integração de Aplicativos Empresariais (EAI, Enterprise Application Integration) entre empresas de uma mesma cadeia produtiva é uma inovação organizacional que proporciona grandes ganhos em competitividade, o que chega a ser vital no atual ambiente de negócios. Essa integração necessita de recursos nem sempre disponíveis nesses sistemas de gestão. Este estudo fez um levantamento dos Sistemas Integrados de Gestão Empresarial (ERP, Enterprise Resource Planning) mais utilizados no Brasil, a respectiva participação no mercado brasileiro e identificou para cada um deles quais seus recursos existentes para integração com outros ERP de outras organizações da cadeia. Tem-se como resultado um panorama no qual se pode apoiar para tomada de decisão ou usá-lo como ponto de partida para pesquisa do nível de utilização do recurso de integração de sistemas entre empresas no Brasil e das barreiras à implementação da mesma. Trata-se de uma pesquisa exploratória que pela análise dos documentos disponibilizados pelos desenvolvedores dos softwares fez a identificação dos recursos de integração dos cinco sistemas ERP mais utilizados no Brasil. / Enterprise Application Integration (EAI) among companies of the same production chain is an organization innovation that provides meaningful gains in competitiveness, which may be critical in current business environment. This integration needs resources not always available in this management systems. This paper investigated Brazil most used ERP, their market share, and identified each ones existing resources to integrate with other ERP in other organizations in the chain. As a result, there is a full view on which to rely for decision making or to be taken as a start for an research on the system integration resource utilization level among Brazil companies and implementation barriers to it. It is a exploratory research, where by means of documentation made available by the softwares developers identified the integration resources of the five ERP systems most used in Brazil.

A semantic model oriented transformation mechanism is developed for the centralization of intra-enterprise data integration. Such a mechanism is especially crucial in the banking domain which is selected in this study. A new domain ontology is constructed to provide basis for annotations. A bottom-up approach is preferred for semantic annotations to utilize existing web service definitions. Transformations between syntactic web service XML responses and semantic model concepts are defined in transformation files. Transformation files are stored and executed in a separate central transformation repository to enhance abstraction and reusability. An RDF-Store is implemented to store transformed RDF data. Inference power of semantic model is exposed by executing semantic queries in the RDF-Store.

A framework for monitoring the dependencies between users, applications, and other system components, combined with the actual access times and frequencies, was proposed. Operating system commands were used to extract event information from the end-user workstations about the dependencies between system, application and infrastructure components. Access times of system components were recorded, and data mining tools were leveraged to detect usage patterns. This information was integrated and used to predict whether or not the failure of a component would cause an operational impact during certain time periods. The framework was designed to minimize installation and management overhead, to consume minimal system resources (e.g. network bandwidth), and to be deployable on a variety of enterprise systems, including those with low-bandwidth and partial-connectivity characteristics. The framework was implemented in a test environment to demonstrate the feasibility of this approach. The system was tested on small-scale (6 computers in the GT CERCS Laboratory over 35 days) and large-scale (76 CPR nodes across the entire GT campus over 4 months) data sets. The average size of the impact topology was shown to be approximately 4% of the complete topology, and this size reduction was related to providing system administrators the capability to better identify those users and resources most likely to be affected by a designated set of component failures during a designated time period.

<p>Denna rapport behandlar ett tämligen outforskat delområde inom elektroniskt handel, nämligen integration av affärssystem och e-handelssystem. Huvudfrågan i denna rapport går ut på att undersöka hur företag har integrerat sitt affärssystem med sitt e-handelssystem. För att besvara huvudfrågan delades den upp i tre delfrågor. Dessa sökte besvara dels på vilken nivå inom Enterprise Application Integration som företagen hade integrerat systemen, dels vilka integrationstekniker företagen använder för att integrera systemen samt dels vilka effekter integrationen medfört för företagen. För att besvara problemställningen utfördes telefonintervjuer med fyra företag. Resultatet av undersökningen var att samtliga företag hade integrerat på Enterprise Application Integrations datanivå, vilket även var den nivå de hade börjat med att integrera. De integrationstekniker som användes varierade. Det var dock inte särskilt vanligt att använda nyare integrationstekniker. Integrationen medförde genomgående positiva effekter för företagen, även om vissa problem kvarstod. Inga större nya problem uppkom dock.</p>
