New Paradigms for Software Application Development: Software architectures and component-based development

摘要

In recent years several technologies and programming languages have appeared for developing software systems. Each one provides advantages and specific implementations to business applications. However, traditional approaches are still in use in many software projects, and therefore the software code was not initially developed with reuse in mind. This situation leads to delays in delivery times, production costs above budget, and possible generation of incomplete/defective software products. The architectures and the component-based development emerge as alternatives for traditional software development. The challenge is software with and for reuse, and interoperability between different technologies, platforms and applications. This paper provides a description of the component-based development and the uses of software architectures. Also, examples of program technologies that implement these concepts are given such as .NET, Web Services, OSGi, ICE, and SCA.
