Service-orientierte Architektur (SOA) ist eine geschäftlich motivierte IT-Architektur, die die Integration von Geschäftsfunktionen als verbundene, wiederverwendbare Dienste (Services) unterstützt. SOA-Migration bezeichnet die Umsetzung existierender Architekturen – die sehr unterschiedlich geartet sein können – in eine SOA. Hierbei liegt der Schwerpunkt meist auf der Anwendungsarchitektur. Bei ...

This paper examines the key managerial factors affecting service-oriented architecture (SOA) implementation in organisations, and whether the implementation of SOA provides benefits to organisations. Based on a cross-sectional survey with 108 organisations, we found that top management support was a significant enabler for SOA implementation. We also found that organisations implementing SOA ga...

SOA has been widely and quickly adopted in different organizations during recent years. SOA enables to solve integration complexity problem and facilitates broadscale interoperability and unlimited collaboration across the organization. In this paper we demonstrate how Service Oriented Architecture (SOA) is important in Business Organizations based on a proposed architecture diagram and also, a...

In this article, we examine how security applies to Service Oriented Architecture (SOA). Before we discuss security for SOA, lets take a step back and examine what SOA is. SOA is an architectural approach which involves applications being exposed as "services". Originally, services in SOA were associated with a stack of technologies which included SOAP, WSDL, and UDDI. This article addresses th...

Over the past years, Service-oriented Architecture (SOA) Systems have been recognized more and more as a serious alternative to common monolithic systems for Enterprise Architectures (EA). An SOA provides a flexible means of effectively mapping business processes to IT processes. However, large IT systems require consistent leadership – IT Governance. For SOAs, governance faces new challenges. ...

We explain the importance of conceptual models for process design with service-oriented architectures (SOA) and illustrate how these models can be used to evaluate the value of SOA. To do so, a methodology is introduced, which comprises both the configuration and the implementation of processes by services and IT components. The approach presented here, makes it possible to evaluate the monetar...

This paper examines the use of Service-Oriented Architecture (SOA) services as core assets in a Software product Line (SPL). After a brief introduction to the main concepts of SOA and SPL, the paper identifies a small set of decisions that are required before implementation of SOA-SPL systems. These decisions have to do with 1) the mapping of SOA concepts to the SPL framework, and 2) an initial...

Service-Oriented Architecture (SOA) enables enterprise for distributed and flexible software development. SOA aims at promoting effective software asset reuse by means of encapsulating functionalities as reusable services accessible through well-defined interfaces. However, one of the challenging problems for the realization of this regard is an ever-increasing need for the design and managemen...

Sources, optical properties, and chemical composition of atmospheric brown carbon (BrC) aerosol are uncertain, making it challenging to estimate its contribution to radiative forcing. Furthermore, optical properties of BrC may change significantly during its atmospheric aging. We examined the effect of photolysis on the molecular composition, mass absorption coefficient, and fluorescence of sec...
