FINANCIAL AND ACCOUNTING INFORMATION SYSTEMS INTEROPERABILITY

The current economic developments have led to substantial changes in terms of how thefinancial and accounting activities are carried. The business environment can be characterized by awidespread consolidation of companies and their grouping in holding companies. Thus, the focus ison consolidation the financial data, and the integration and interoperability of the financial andaccounting applications and also the integrated information systems have a major significance. Withthe development of the Internet, the architecture of the informatics applications has really beenaffected, this resulted in substantial changes in how the solutions are distributed and accessed aswell. The present paper analyses and provides viable solutions for the use of the technologieswhich are applied in the interoperability of the financial and accounting information systems, in thecontext of economic activity globalization. The dynamism and economic processes development in thenew context have generated important researches in the informatics field which had resulted insimplifying the access way to applications (by simply using a Web browser) and also developing theinterconnecting technologies for the financial and accounting information systems – theirinteroperability represents, in fact, the Keyword.On this economic scenery, the financial and accounting information systems become very importantsolutions to integrate different business applications and also to offer a complete perspective for allthe business.SOA (Service Oriented Architecture), Informational Integrated Systems, XML (eXtended MarkupLanguage), Visual Studio .NET, Web Services

Web Services Technology Infrastructure

Web Services using eXtensible Markup Language (XML) based standards are becoming the new archetype for enabling business to business collaborations. This paper describes the conceptual architecture and semantics of constructing and consuming Web Services. It describes how Web Services fit into the enterprise application environment. It discusses Web Services security. Finally, it outlines the flaws of Web Services in their current state

On Systematic Design of Protectors for Employing OTS Items

Off-the-shelf (OTS) components are increasingly used in application areas with stringent dependability requirements. Component wrapping is a well known structuring technique used in many areas. We propose a general approach to developing protective wrappers that assist in integrating OTS items with a focus on the overall system dependability. The wrappers are viewed as redundant software used to detect errors or suspicious activity and to execute appropriate recovery when possible; wrapper development is considered as a part of system integration activities. Wrappers are to be rigorously specified and executed at run time as a means of protecting OTS items against faults in the rest of the system, and the system against the OTS item's faults. Possible symptoms of erroneous behaviour to be detected by a protective wrapper and possible actions to be undertaken in response are listed and discussed. The information required for wrapper development is provided by traceability analysis. Possible approaches to implementing “protectors” in the standard current component technologies are briefly outline

A Peer-to-Peer Middleware Framework for Resilient Persistent Programming

The persistent programming systems of the 1980s offered a programming model that integrated computation and long-term storage. In these systems, reliable applications could be engineered without requiring the programmer to write translation code to manage the transfer of data to and from non-volatile storage. More importantly, it simplified the programmer's conceptual model of an application, and avoided the many coherency problems that result from multiple cached copies of the same information. Although technically innovative, persistent languages were not widely adopted, perhaps due in part to their closed-world model. Each persistent store was located on a single host, and there were no flexible mechanisms for communication or transfer of data between separate stores. Here we re-open the work on persistence and combine it with modern peer-to-peer techniques in order to provide support for orthogonal persistence in resilient and potentially long-running distributed applications. Our vision is of an infrastructure within which an application can be developed and distributed with minimal modification, whereupon the application becomes resilient to certain failure modes. If a node, or the connection to it, fails during execution of the application, the objects are re-instantiated from distributed replicas, without their reference holders being aware of the failure. Furthermore, we believe that this can be achieved within a spectrum of application programmer intervention, ranging from minimal to totally prescriptive, as desired. The same mechanisms encompass an orthogonally persistent programming model. We outline our approach to implementing this vision, and describe current progress.Comment: Submitted to EuroSys 200

Network-based business process management: embedding business logic in communications networks

Advanced Business Process Management (BPM) tools enable the decomposition of previously integrated and often ill-defined processes into re-usable process modules. These process modules can subsequently be distributed on the Internet over a variety of many different actors, each with their own specialization and economies-of-scale. The economic benefits of process specialization can be huge. However, how should such actors in a business network find, select, and control, the best partner for what part of the business process, in such a way that the best result is achieved? This particular management challenge requires more advanced techniques and tools in the enabling communications networks. An approach has been developed to embed business logic into the communications networks in order to optimize the allocation of business resources from a network point of view. Initial experimental results have been encouraging while at the same time demonstrating the need for more robust techniques in a future of massively distributed business processes.active networks;business process management;business protocols;embedded business logic;genetic algorithms;internet distributed process management;payment systems;programmable networks;resource optimization
