Customizing Enterprise Software as a Service Applications: Back-End Extension in a Multi-tenancy Environment
Since the emerge of Salesforce.com, more and more business applications tend to move towards Software as a Service. In order to target Small and Medium-sized Enterprises, platform providers need to lower their operational costs and establish an ecosystem of partners, customizing their generic solution, to push their products into spot markets. This paper categorizes customization options, identifies cornerstones of a customizable, multi-tenancy aware infrastructure, proposes a framework that encapsulates multi-tenancy, and introduces a technique for partner back-end customizations with regard to a given real-world scenario.

Generic Web Services - Extending Service Scope While Preserving Backwards Compatibility
An apparatus for sorting blocks made of concrete or concrete-like material, in particular paving slabs, having a vibration arrangement and a sorting arrangement which slopes with respect to the horizontal, has an entry part for the blocks which are to be sorted and a sorting part, which has at least one collecting channel running in the conveying direction. The collecting channel has a central part and two lateral run-on surfaces arranged thereon, the width of the central part corresponding at least approximately to one of the two shorter edge lengths of the blocks which are to be sorted. The run-on surfaces are provided with stop elements, the stop elements on one run-on surface being offset in the longitudinal direction with respect to the stop elements on the other run-on surface.

Gain in Transparency versus Investment in the EPC Network - Analysis and Results of a Discrete Event Simulation Based on a Case Study in the Fashion Industry
The diffusion rate of Radio Frequency Identification (RFID) technology in supply chains is lower than expected. The main reason is the doubtful Return On Investment (ROI) mainly due to high tag prices. In this contribution, we leverage a prototypical RFID implementation in the fashion industry, extend this prototype by a discrete event simulation, and discuss the impact of an Electronic Product Code (EPC)-enabled supply chain concerning higher visibility. Thereby, we illustrate the benefit of the EPC network for Supply Chain Event Management (SCEM). Future researchers are provided with the simulation data which is available online and can be investigated.

An Aggregating Discovery Service for the EPCglobal Network
Although the achievements of EPCglobal standardization efforts in the last years are substantial and the diffusion of the EPCglobal network continues, a service to access item-level information stored at potentially unknown supply chain partners is still missing. Without this 'Discovery Service' the EPCglobal network cannot be used with unknown business partners. In this contribution we present a novel Discovery Service approach. In contrast to other Discovery Service approaches we use the Discovery Service to aggregate the data of interest. This eliminates problems other approaches cannot solve, e.g. assuring data ownership, low access control maintenance effort, and minimal complexity for the information requester. We present a requirements model, describe the implementation of our Discovery Service approach, and compare it to existing Discovery Service approaches. Finally we show how to overcome scalability challenges to implement our Discovery Service approach in a real-world environment.

Data Security in Service-Oriented Architectures
Due to standardized interfaces and loose coupling of services, serviceoriented architectures provide the possibility for close interaction between different organizations and communities. But this also introduces new risks: To have under control where which data is processed becomes increasingly difficult. This paper highlights that current approaches for ensuring data privacy and required security mechanisms are no longer adequate under these changing conditions and presents possible solutions discussed by researchers and developers. Additionally, economic implications of data privacy and security are considered.

Developing Web applications for mobile devices
Today, even small mobile devices access the Internet. Therewith, mobility issues have become an important technical and economic topic - not only in new but in proven and successful Web applications as well. The main problem derives from a growing development of heterogeneity in hardware and software of mobile devices. To overcome this problem, this paper presents a framework to develop Web applications for mobile devices. This framework issues important points when developing web application that also focuses on mobile users. This includes completely new developments, as well as development that issue an upgrade of existing Web applications to mobile devices. An important element in this framework is the employment of the fairly new CC/PP standard.

Service-oriented support of cooperative workflows considerations for urban planning processes
Web-based information sources have evolved to an essential element in our daily and professional life. To process this faster and faster growing amount of information, web portals provide personalized access to specific information and communication services. In this paper, an example from urban planning is given. In this workflow, different actors are interacting in an ad-hoc manner. Therefore, a Portal Architecture has been built up, which provides the relevant information. This paper proposes a Service Orientated Architecture to provide access to business processes, software applications and hardware resources in a workflow oriented way.
