Comparison between information system architectures
نویسنده
چکیده
There are different types of information system architectures, but there has not been a structural comparison between the different types. I develop in this paper a structured approach to assess the three main Information System architectures, Enterprise Resource Planning, Service-Oriented Architecture and Multi Agent Systems, based on a structured approach. Furthermore, I provide in this paper an extensive analysis of the key characteristics of the three main IS architectures. In this paper, I develop a systematic and structured approach to pair wise compare and assess these key characteristics of the main architectures based on the IS development framework as developed by Zachman. The aim of this paper are twofold, first, to develop a framework which is suitable for comparing IS architectures and second, comparing the three architectures. The framework I developed is based on the Zachman framework and the views of the original framework are grouped together in due to the complexity of comparing the original framework for the three architectures, this resulted in a new 6x1 framework. The results of the comparison show that there are several key difference between the architectures in the areas of what kind of data is stored, the ability to keep working with legacy systems, the amount of complexity and uncertainty in which these architectures can operate and how the network which corresponds with these architectures is arranged.

Service-Oriented Information Systems Architectures In Supply Chain Management For Hybrid Value Bundles - A Structured Comparison
To avoid low-price strategies, companies are seeking intensively for new ways to distinguish themselves from the competition in a global market. A promising answer to this challenge is to extend existing offers from independent products and services to integrated problem-solving solutions for specific customer requirements. These integrated solutions are called product-service systems or hybrid...
متن کاملPerformance Comparison between Two Grid Information Service Architectures
Both hierarchical and unstructured (Peer-to-Peer or P2P) architectures can be used to construct a Grid information service (GIS) and the selection of the architecture is a factor affecting the performance of the GIS. In this paper, we have investigated and compared the performance between these two GIS architectures. We describe a P2P GIS architecture based on unstructured multi-source multicas...

This paper presents a comparison of di erent model architectures for TIMIT phoneme recognition. The baseline is a conventional diagonal covariance Gaussian mixture HMM. This system is compared to two di erent hybrid MLP/HMMs, both adhering to the same restrictions regarding input context and output states as the Gaussian mixtures. All free parameters in the three systems are jointly optimised u...
