Transactional Services for the Web

Abstract: This paper investigates a new paradigm in transactional services, specially tailored for Internet purposes. This new paradigm considers transactions (called I-Transactions) as user’s atomic actions spanned upon multiple databases present in the Internet. Whereas classical transactions are designed to cope with multiple users accessing a particular DBMS, or a federation of well-known DBMS, inversely, I-Transactions are related to a single user, i.e. they are not bounded to a particular DBMS, or a federation of DBMS. Therefore, I-Transactions are self-managed since they cannot be ruled by a common global transaction manager. They provide an atomic action upon a set of DBMS that possibly do not know each other (they are determined when a transaction is initiated) and which may not be simultaneously accessed again by another I-Transaction. They are tailored to be used in the Internet environment, which now does not support many kind of transactional facility, and are designed to be easily integrated in exis ting Internet applications. This paper proposes a description of the I-Transactions and the constraints related to their utilization, in particular from the security point of view. It also outlines the major differences among I-Transactions and the CORBA Transaction Service, TIP or the X/OPEN DTP. This paper considers two architectures for supporting I-Transactions: direct interactions among the participants or brokered interactions with the introduction of transaction brokers (agencies).

CORBA on WWW: evaluative framework for interoperability issues

Abstract: In spite of various research efforts to seamlessly integrate distributed object systems (DOS) and World Wide Web (WWW or Web), with the main aim of bringing together benefits of both, interoperability concerns (issues) in the integration of DOS and WWW have not been addressed adequately in the literature. Interoperability is the fundamental concern when systems, such as software components, architectural elements interacting with each other. To prove the adequacy of interfaces (bridges) between two interoperable systems or to evaluate the sufficiency of such interoperability, shortcomings of the interfacing needs to be identified. Moreover, a qualitative and/or quantitative framework is required to evaluate the two different interoperability mechanisms. The main focus of the paper is to identify and highlight some interoperability concerns that could emerge in the development of heterogeneously distributed CORBA applications on WWW. We further propose a framework for evaluating interoperability, that provides a uniform strategy to compare solutions that provides interoperability solutions.
