With recent advances in mobile technologies and infrastructures, there are increasing demands for ubiquitous access to networked services. These services, generally known as m-services, extend supports from Web browsers on personal computers to handheld devices, such as mobile phones and PDAs. However, in general, the capabilities and bandwidth of these devices are significantly inferior to desktop computers over wired connections, which have been assumed by most Internet services. Instead of redesigning or adapting m-services in an ad-hoc manner for multiple platforms available in handheld devices, we propose a methodology for such adaptation based on three tiers: user interface views, data views, and process views. These views provide customization and help balance security and trust. User interface views provide alternative presentations of inputs and outputs. Data views summarize data over limited bandwidth and map heterogeneous data sources. In addition, we introduce a novel approach of applying process views to m-service adaptation, where mobile users may execute a more concise version or modified procedures of the original process. The process view also serves as the key mechanism for integrating user interface views and data views. In addition, we present a formal model on view consistency and integrity in our methodology. We demonstrate the feasibility of our methodology by extending a service negotiation subsystem into an m-service with multi-platform support.

“…Motivated by views in federated object databases [26], we propose the use of process views as a fundamental mechanism for flexible m-service adaptation. A process view is a structurally correct subset of a process definition derived from a base process (as defined in [17], [28]).…”

With recent advances in mobile technologies and infrastructures, there are increasing demands for mobile users to connect to existing collaboration systems. This requires extending supports from web browsers on personal computers to SMS, WAP, and PDAs. However, in general, the capabilities and bandwidth of these mobile devices are significantly inferior to desktop computers over wired connections, which have been assumed by most collaboration systems. Instead of redesigning or adapting collaboration systems in an ad-hoc manner for different platforms in a connected society, we propose a methodology of such adaptation based on three tiers of views: user interface views, data views and process views. These views provide customization and help balance security and trust. User interface views provide alternative presentations of inputs and outputs. Data views summarize data over limited bandwidth and display them in different forms. Furthermore, we introduce a novel approach of applying process views to mobile collaboration process adaptation, where mobile users may execute a more concise version or modified procedures. The process view also serves as the centric mechanism for integrating user interface views and data views. This methodology also discusses ways to support external mobile users who have no agent support, customizable degree of agent delegation and the employment of constraint technology for negotiation. We demonstrate the feasibility of our methodology by extending a web-based meeting scheduler into a distributed mobile one.

“…An object-oriented data model like ODMG-93 [Cat94, Cat963 can serve as the canonical data model for the global layer. An example is the IRO-DB system [GFF97,GGp96,RFFS95,BFHK94] which provides a standard ODMG interface for each participating local system to alleviate data model differences.…”

Object technology has received considerable attention in the re cent years for the integration of various local data sources in a multi-database system (MDBS). An object-oriented data model like ODMG-93 can serve as the canonical data model for the global layer in the MDBS. The ODMG-93 standard defines a closed nested ACID transaction model without intra-transaction parallelism. Although the nested transaction model provides special support for distributed computing enviromnents, the implications of its usage as a global transaction model for MDBS have so far not been examined.In this paper, we present a simple and practical method to implement global nested transaction management for ODMGcompliant multi-database systems. The main contribution of our work is the adaption of the ticket method to achieve global serializability for global nested transactions that conform to ODMG. Our approach is also applicable to OMG's common object request broker architecture. We have successfully implemented our global nested transaction model within the IRO-DB multi-database system.
