CREWS : a Component-driven, Run-time Extensible Web Service framework

Parry, Dominic Charles January 2004 (has links)
There has been an increased focus in recent years on the development of re-usable software, in the form of objects and software components. This increase, together with pressures from enterprises conducting transactions on the Web to support all business interactions on all scales, has encouraged research towards the development of easily reconfigurable and highly adaptable Web services. This work investigates the ability of Component-Based Software Development (CBSD) to produce such systems, and proposes a more manageable use of CBSD methodologies. Component-Driven Software Development (CDSD) is introduced to enable better component manageability. Current Web service technologies are also examined to determine their ability to support extensible Web services, and a dynamic Web service architecture is proposed. The work also describes the development of two proof-of-concept systems, DREW Chat and Hamilton Bank. DREW Chat and Hamilton Bank are implementations of Web services that support extension dynamically and at run-time. DREW Chat is implemented on the client side, where the user is given the ability to change the client as required. Hamilton Bank is a server-side implementation, which is run-time customisable by both the user and the party offering the service. In each case, a generic architecture is produced to support dynamic Web services. These architectures are combined to produce CREWS, a Component-driven Runtime Extensible Web Service solution that enables Web services to support the ever changing needs of enterprises. A discussion of similar work is presented, identifying the strengths and weaknesses of our architecture when compared to other solutions.

CosmosLoader : uma ferramenta de apoio ao gerenciamento de configuração baseado no modelo Cosmos* / CosmosLoader : a support framework for configuration management based on the Cosmos* model

Gayard, Leonel Aguilar, 1983- 23 August 2018 (has links)
Orientador: Cecília Mary Fischer Rubira / Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Computação / Made available in DSpace on 2018-08-23T21:56:13Z (GMT). No. of bitstreams: 1 Gayard_LeonelAguilar_M.pdf: 1532057 bytes, checksum: 8324b0d9bd3eebedc13daca6f31c7c6b (MD5) Previous issue date: 2013 / Resumo: Nos últimos anos, o desenvolvimento baseado em componentes (DBC) e a arquitetura de software emergiram como disciplinas complementares para promover o reuso no desenvolvimento de software. O desenvolvimento baseado em componentes promove o desenvolvimento de componentes reutilizáveis e a formação de novos sistemas de software a partir da integração de componentes existentes. A arquitetura de um sistema de software descreve o sistema em termos de seus componentes arquiteturais, das propriedades destes e das conexões entre eles. Modelos de componentes possibilitam concretizar elementos de DBC como componentes e conectores a partir de conceitos tradicionais de desenvolvimento de software, como por exemplo, orientação a objetos e arquivos, de modo que um conjunto de classes e arquivos complementares podem formar um componente se seguirem as regras do modelo. A adequação a um modelo de componentes oferece benefícios para o sistema de software: por exemplo, o modelo de componentes EJB possibilita que um componente seja implantado em um contêiner e se beneficie do gerenciamento de segurança e transparência de localização oferecidos pelo contêiner; o modelo Cosmos estabelece regras para a criação de componentes baseados em conceitos de linguagens orientadas a objetos, como classes, interfaces e pacotes. Assim, a integração de componentes para a composição de um sistema de software de acordo com uma arquitetura e um modelo de componentes se torna uma atividade importante no desenvolvimento de um novo sistema de software. Uma configuração concreta é um conjunto de determinadas versões de componentes de software conectados de acordo com uma arquitetura. No entanto, observa-se que, se modelos facilitam a criação de componentes de software, ainda é necessário um esforço de desenvolvimento para integrar componentes e formar novos sistemas. O uso de ambientes de desenvolvimento orientados a arquitetura e DBC, e também de ferramentas de automatização, reduzem o esforço necessário para a integração de componentes. O ambiente Bellatrix é um ambiente de desenvolvimento integrado que permite a especificação de elementos arquiteturais e a modelagem de arquiteturas de software. No entanto, ainda existe um hiato entre a arquitetura de um sistema modelada no ambiente Bellatrix e a configuração do sistema a partir de componentes concretos. Esta dissertação apresenta a ferramenta CosmosLoader, que auxilia o gerenciamento de configurações de componentes baseados no modelo Cosmos. A solução proposta se baseia na extensão do ambiente Bellatrix e no modelo de componentes Cosmos* ("Cosmos estrela"), que estende o modelo Cosmos com o conceito de composição hierárquica de componentes. Por fim, são descritos estudos de caso realizados com essas ferramentas / Abstract: In the last years, Component-Based Development (CBD) and Software Architecture emerged as complementary disciplines that promote reuse in software development. Component-Based Development promotes the development of reusable software components and the creation of new software systems by integrating existing software components. The architecture of a software system describes such system in terms of its architectural components, their properties and the connections between them. Component models materialize concepts from CBD such as components and connectors from traditional concepts of software development, such as object orientation and files, so that a set of classes and complementary files form a component if they follow the component model's rules. The adequacy to a component model brings benefits to a software system: for instance, the EJB component model allows a component to be deployed to a container and benefit from the security management and location transparency provided by the container; the Cosmos component model allows the creation of components using only concepts from object-oriented languages, such as classes, interfaces and packages. Therefore, the integration of components to compose a new software system according to an architecture and a component model becomes an important activity in the development of a new software system. A concrete configuration is the set of specific versions of software components connected according to an architecture. However, it can be observed that while models ease the creation of software components, a development effort is still necessary to integrate components and form new systems. The use of development environments oriented towards architecture and CBD, and also of automations tools, reduce the effort needed to integrate components. The Bellatrix development environment is an integrated development environment that allows the specification of architectural elements and modeling of software architectures. However, there still is a gap between the architecture of a system modeled in Bellatrix and the configuration of a system from concrete software components. This dissertation presents the CosmosLoader tool, which assists in managing the configuration of components based on the Cosmos model. The proposed solution is based on an extension to the Bellatrix development environment and on the Cosmos* component model ("Cosmos star"), which extends the Cosmos component model with hierarchical composition of components. Finally, case studies using these tools are described / Mestrado / Ciência da Computação / Mestre em Ciência da Computação

Investigation and Implementation of a Live Connection between Configura CET and Revit Architecture 2009

Pintar, Freddie January 2009 (has links)
Building Information Modeling -BIM- is an innovative method to seamlessly bridgecommunication within the architecture, engineering and construction industries.With BIM software you can exchange information during the design, construction,and maintaining. BIM can be seen as a continuation of the CAD software, wherethe users exchanged information by word of mouth, now is made automatically.To get the effect required for BIM one or more CAD-systems have to work togetherto exchange information. Revit Architecture is an application by Autodeskwhere BIM is used from the design and construction to the documentation andmaintaining of a building. Configura is one of the major software developers of interiorsolutions and want to integrate their software with Revit Architecture. Theconcept of objects in both software system suit well to be used in BIM and witha live connection these could be shared between the applications. One of the conclusionsin this investigation was that the only way to have integration betweenthe applications was to use the API provided by Autodesk. And therefore theimplementation is limited to the function in it. Revit API is a powerful programmingenvironment that let 3rd party software extend the functionality in Revit.The results show how Remote Procedure Call as a communication tool can beused to exchange data between the applications, how different type of data can berepresented in both applications, and why we cannot have a live synchronization.

Software architecture evaluation for framework-based systems.

Zhu, Liming, Computer Science & Engineering, Faculty of Engineering, UNSW January 2007 (has links)
Complex modern software is often built using existing application frameworks and middleware frameworks. These frameworks provide useful common services, while simultaneously imposing architectural rules and constraints. Existing software architecture evaluation methods do not explicitly consider the implications of these frameworks for software architecture. This research extends scenario-based architecture evaluation methods by incorporating framework-related information into different evaluation activities. I propose four techniques which target four different activities within a scenario-based architecture evaluation method. 1) Scenario development: A new technique was designed aiming to extract general scenarios and tactics from framework-related architectural patterns. The technique is intended to complement the current scenario development process. The feasibility of the technique was validated through a case study. Significant improvements of scenario quality were observed in a controlled experiment conducted by another colleague. 2) Architecture representation: A new metrics-driven technique was created to reconstruct software architecture in a just-in-time fashion. This technique was validated in a case study. This approach has significantly improved the efficiency of architecture representation in a complex environment. 3) Attribute specific analysis (performance only): A model-driven approach to performance measurement was applied by decoupling framework-specific information from performance testing requirements. This technique was validated on two platforms (J2EE and Web Services) through a number of case studies. This technique leads to the benchmark producing more representative measures of the eventual application. It reduces the complexity behind the load testing suite and framework-specific performance data collecting utilities. 4) Trade-off and sensitivity analysis: A new technique was designed seeking to improve the Analytical Hierarchical Process (AHP) for trade-off and sensitivity analysis during a framework selection process. This approach was validated in a case study using data from a commercial project. The approach can identify 1) trade-offs implied by an architecture alternative, along with the magnitude of these trade-offs. 2) the most critical decisions in the overall decision process 3) the sensitivity of the final decision and its capability for handling quality attribute priority changes.

Formal Analysis of Component Adaptation Techniques

Kanetkar, Kavita Vijay 30 April 2002 (has links)
Increasing demand for commercial software components has led to a development and deployment issue of overcoming differences between the customer requirements and developer specifications for the component. Component Adaptation is one solution to the issue. This thesis focuses on modeling the adaptations to an Enterprise JavaBeanTM component using the Z notations and carrying out the adaptations using Active Interfaces adaptation technique. We also formally model the Active Interfaces adaptation technique.

The Common Tutor Object Platform

Nuzzo-Jones, Goss F 09 January 2006 (has links)
The Common Tutor Object Platform (CTOP) was designed as a lightweight component framework for creating and deploying applications relating to Intelligent Tutoring Systems. The CTOP supports a runtime for intelligent tutoring system content deployment, a content development environment, an extensive reporting tool, and other smaller applications. The CTOP was designed with future development in mind, allowing easy specification of new base objects and extension points for future development. It has been used as the foundation of the Assistments Project, a wide scale server based ITS deployment. This thesis documents the software engineering aspects of the project. The Assistments Project is capable of supporting a quarter of targeted students in Massachusetts, and optimistically scalable to the entire state and beyond.
