Layered architecture revisited - Comparison of research and practice

چکیده
Organizing a software architecture into layers has been one of the earliest architectural styles ever used. Even today layered structure is a very common architectural style used in various industrial systems. However, we have observed that the usage of layered architectural style varies greatly in different contexts. This paper aims to compare the notion of software architecture layers in research literature as well as in industrial practice. Firstly, we performed a systematic literature review of research articles on layered software architectures; we also reviewed selected books of software architecture. Secondly, to understand the practice, we investigated a number different recent architecture documents to cover the current usage of layered architectures. Our results indicate that there is very little actual research done on layered architectures. The current usage of layered structures seems to be more complex than reported before. This gap between the research and practice needs to be bridged by researchers.

Architecture Students’ Understanding of Landscape Issues in Design Studios (A Comparison Approach in Some Tehran Architecture Schools)
Without the surrounding environment of a site, architecture loses its full meaning. In the evolutionof the design process, a site's environment should be understood as the integral factor within which a designed productor artifact is expected to perform. The environment is not of secondary priority. Every building is intertwined with itscontext; context being its physical, visual and ecological...
متن کاملFinite element comparison of single, bi-layered and three-layered tube hydroforming processes
In this paper, single, bi-layered and three-layered tube hydroforming processes were numerically simulated using the finite element method. It was found that the final bulges heights resulted from the models were in good agreement with the experimental results. Three types of modeling were kept with the same geometry, tube material and process parameters to be compared between the obtained hydr...
متن کاملIntertextual Reading of Postmodern Architecture (Based on Historicist postmodern architecture and Deconstruction)
Postmodernism is a very ambiguous term. It attracted many researchers from different fields of knowledge in the late 1960s. This article explains intertextuality as a critical means to derive its concepts and components in order to understand the hidden layers of meaning in postmodern pluralist ideology. Variable thoughts of postmodern architecture have been divided into two categories—Hi...

The aim of this paper is to compare the static deflections and stress results of layered and functionally graded composite beams under static load. In the comparison study, the results obtained for a cantilever beam under point load. The Timoshenko beam and the Euler-Bernoulli beam theories are used in the beam model. The energy based Ritz method is used for the solution of the problem and alge...

E-readiness is one of the major prerequisites for effective implementation of e-government. For the correct implementation of e-government, it is needed to accurately assess the state of e-readiness in desired community. In this regard, there are models to assess, but the correct choice of model is one of the most important challenges in this area. The process of evaluating and selecting the ap...
