Creating Custom Containers With Generative Techniques, Gabriel A. Moreno

Gabriel A. Moreno

Component containers are a key part of mainstream component technologies, and play an important role in separating nonfunctional concerns from the core component logic. This paper addresses two different aspects of containers. First, it shows how generative programming techniques, using AspectC++ and metaprogramming, can be used to generate stubs and skeletons without the need for special compilers or interface description languages. Second, the paper describes an approach to create custom containers by composing different non-functional features. Unlike component technologies such as EJB, which only support a predefined set of container types, this approach allows different combinations of non-functional features to …

Service Grid For Business Computing, Zongwei Luo, Jia Zhang, Rosa Badia

Jia Zhang

In this chapter, we will introduce an advanced topic of grid computing – Web services-oriented grid for business computing. Web services represent a new concept of computing that enables diverse and distributed resources to communicate with each other based upon a set of standards. We will discuss what values the marriage of Web services and grid computing can bring to business computing and the current state of the art of the field. The layout of the chapter is as follows: Grid computing overview; Web services orientation; Service oriented grid; Integrated service platform for integration; and Challenges and considerations.

Privacy Issues Of Applying Rfid In Retail Industry, Haifei Li, Patrick C.K. Hung, Jia Zhang, David Ahn

Jia Zhang

This case study describes the privacy issues of applying Radio Frequency Identification (RFID) in the retail industry. With the dramatic price drop of RFID tags, it is possible that RFID be applied to individual items sold by a retailer. However, the RFID technology poses critical privacy challenges. In this study, we analyze the potential privacy issue of RFID utilization, and we propose a privacy authorization model aiming for precisely defining RFID privacy policies for the retail industry.

Auction-Based Pricing Model For Web Service Providers, Jia Zhang, Ning Zhang, Liang-Jie Zhang

Jia Zhang

Applying auctions to Web services selection and invocation calls for examination due to the unique features of Web services, such as interoperable machine-to-machine interactions and reenterable bargaining services. In this paper we propose a formal model for Web services-based auctions. Examining one-sided sealed auction type, we prove mathematically that service requestors’ risk preferences could lead to different pricing strategies for service providers towards higher profit. We argue that Service Level Agreement (SLA) documents can be used to analyze service requestors’ preferences. On top of WS-Agreement, we propose a basic service requestor risk preference elicitation algorithm, as well as a historical …

A Mobile Agents-Based Approach To Test The Reliability Of Web Services, Jia Zhang

Jia Zhang

The paradigm of web services has been transforming the internet from a repository of data into a repository of services, or so-called web services. As more and more web services are published on the internet, how to opt for an appropriate and trustworthy web service poses a big challenge. In this paper we propose a mobile agents-based approach that selects reliable web service components in a cost-effective manner.

A Service-Oriented Multimedia Componentization Model, Jia Zhang, Liang-Jie Zhang, Francis Quek, Jen-Yao Chung

Jia Zhang

As Web services become more and more popular, how to manage multimedia Web services that can be composed as value-added service solutions remains challenging. This paper presents a service-oriented multimedia componentization model to support Quality of Service (QoS)-centered, device-independent multimedia Web services, which seamlessly incorporates cuttingedge technologies relating to Web services. A multimedia Web service is divided into control flow and data flow, each can be delivered via different infrastructures and channels. Enhancements are proposed to facilitate Simple Object Access Protocol (SOAP) and Composite Capability/Preference Profiles (CC/PP) protocols to improve their flexibility to serve multimedia Web services. We present a …

Enabling Predictable Assembly, Scott A. Hissam, Gabriel A. Moreno, Judith Stafford, Kurt C. Wallnau

Gabriel A. Moreno

Demands for increased functionality, better quality, and faster time-to-market in software products continue to increase. Component-based development is the software industry’s response to these demands. The industry has developed technologies such as EJB and CORBA to assemble components that are created in isolation. Component technologies available today allow designers to plug components together, but do little to allow the developer to reason about how well they will play together. Predictable assembly focuses on issues related to assembling component-based systems that predictably meet their quality attribute requirements. This paper introduces prediction-enabled component technology (PECT) as a means of packaging predictable assembly …

Packaging And Deploying Predictable Assembly, Scott A. Hissam, Gabriel A. Moreno, Judith Stafford, Kurt C. Wallnau

Gabriel A. Moreno

Significant economic and technical benefits accrue from the use of pre-existing and commercially available software components to develop new systems. However, challenges remain that, if not adequately addressed, will slow the adoption of software component technology. Chief among these are a lack of consumer trust in the quality of components, and a lack of trust in the quality of assemblies of components without extensive and expensive testing. This paper describes predictionenabled component technology (PECT). A PECT results from integrating component technology with analysis models. An analysis model permits analysis and prediction of assembly-level properties prior to component composition, and, perhaps, …

Statistical Models For Empirical Component Properties And Assembly-Level Property Predictions: Toward Standard Labeling, Gabriel A. Moreno, Scott A. Hissam, Kurt C. Wallnau

Gabriel A. Moreno

One risk inherent in the use of software components has been that the behavior of assemblies of components is discovered only after their integration. The objective of our work is to enable designers to use known (and certified) component properties as parameters to models that can be used to predict assembly-level properties. Our concern in this paper is with empirical component properties and compositional reasoning, rather than formal properties and reasoning. Empirical component properties must be measured; assessing the effectiveness of predictions based on these properties also involves measurement. This, in turn, introduces systematic and random measurement error. As a …
