The lack of transparency surrounding cloud service provision makes it difficult for consumers to make knowledge based purchasing decisions. As a result, consumer trust has become a major impediment to cloud computing adoption. Cloud Trust Labels represent a means of communicating relevant service and security information to potential customers on the cloud service provided, thereby facilitating informed decision making. This research investigates the potential of a Cloud Trust Label system to overcome the trust barrier. Specifically, it examines the impact of a Cloud Trust Label on consumer perceptions of a service and cloud service provider trustworthiness and trust in the …
A Machine-Learning Approach For Workflow Identification From Low-Level Monitoring Information, Thorsten Stein
A Machine-Learning Approach For Workflow Identification From Low-Level Monitoring Information, Thorsten Stein
Theses
Knowing which workflows are executed within Service Oriented Architectures (SOA) is essential for successful IT management. In many cases, SOAs grew out of previous existing IT architectures; existing components are used as single services and therefore as parts of newly created workflows. Since such workflows consist of newly developed and legacy services, traditional workflow management systems often cannot be applied. This thesis presents a method for gathering information about the executed workflows within such heterogeneous environments. An implementation of a framework is presented. This framework allows the training of machine-learning algorithms with workflow models and the mapping of low-level monitoring …
Amvc: A Loosely-Coupled Architecture For Component-Based Clients, Brendan Lawlor
Amvc: A Loosely-Coupled Architecture For Component-Based Clients, Brendan Lawlor
Theses
There is an architectural deficit in most currently undertaken rich client applications: In n-tier applications the presentation layer is represented as a single layer. This is as true of browser-based rich clients (Rich Internet Applications) as of rich desktop clients since both are designed along component-based, event-driven lines. The result of creating rich clients without sufficient application architecture underpinning is often tightly-coupled code of unnecessary complexity, with the associated high cost of maintenance. No commonly understood pattern is currently evident that would allow rich client components to be combined into a loosely coupled application. This paper describes the theory and …
A Toolkit For Xml-Based And Process-Oriented Application Integration, Volker Münch
A Toolkit For Xml-Based And Process-Oriented Application Integration, Volker Münch
Theses
Systems integration is hard work; different architectures with different interfaces and an innumerable amount of Legacy applications with non-standard interfaces exist. However the needs to meet changing business requirements and to implement faster and optimised procedures within an enterprise and in cooperation with other external enterprises mean that there is a continuing demand for such integration strategies and products. Integration was often an activity separate from system development and could not be accomplished without re-involving system designers and developers. Such a process is therefore inefficient and costly. This thesis proposes a process-oriented integration strategy that combines the tasks of integration …
Design And Implementation Of An Intranet-Solution Especially With Workflow Aspects, Robert Loew
Design And Implementation Of An Intranet-Solution Especially With Workflow Aspects, Robert Loew
Theses
An Intranet support a new or simply an easier information system for all the workers within a company using internet technology. On the one hand, employees can use Web technology and very simple tools to provide and navigate information. On the other hand, the costly and time-consuming business of installing and maintaining software on local PCs can be avoided by using Browser-based Intranet applications. Ideally, it would be possible to access all forms of information processing using one and the same Web browser. This is the aim of the Intranet Project upon which this thesis is based.

Design And Code Generation Concepts For Statechart Diagrams Of The Uml V1.1 In Concurrent Environments, Pierre Metz
Design And Code Generation Concepts For Statechart Diagrams Of The Uml V1.1 In Concurrent Environments, Pierre Metz
Theses
This thesis deals with code generation concepts for the statechart diagrams of the UML vl.l. It explores implementation approaches for mapping statechart diagrams to code. It also focuses on modelling rules for consistent design of dynamic object behaviour. Most of the given object-oriented (00) methods have statechart diagrams as their centre. It is proposed to use statechart diagrams to model the internal behaviour of objects and lifecycles, respectively. Generally, statechart diagrams are used in the area of analysis and design of reactive systems such as realtime- and embedded-systems. This thesis introduces different existing implementation patterns and shows how they can …
