Federated Information Systems

Businesses can change their business structure by merging with other companies or, on the other end of the spectrum, by smoothly outsourcing some of their business processes to other more specialized parties. In this paper we will concentrate on conceptual modelling of merging and outsourcing information systems. Merging of a collection of information systems will be defined as the construction of a global information system that contains exactly the functionality of the original collection of systems. Such global information systems are called federated information systems, when we wish to address the situation where the component systems are so-called legacy systems; i.e. systems that are given beforehand and which are to interoperate in an integrated single framework in which the legacy systems are to maintain as much as possible their respective autonomy. Two major problems in constructing federated information systems concern achieving and maintaining consistency and a uniform representation of the data on the global level of the federation. The process of creation of uniform representations of data is known as data extraction, whereas data reconciliation is concerned with resolving data inconsistencies. Outsourcing of an information system, on the other hand, will be defined as the handing over of part of the functionality of the original system to an outside party (the supplier). Such functionality typically involves one or more operations, where each operation satisfies certain input- and output requirements. These requirements will be defined in terms of the ruling service level agreements (SLAs). We will provide a formal means to ensure that the outsourcing relationship between outsourcing party and supplier, determined by a SLA, satisfies specific correctness criteria. Formal specifications as offered in this paper can prove their value in the setup and evaluation of outsourcing contracts. We shall describe a uniform semantic framework for specification of both federated and outsourced information systems based on the UML/OCL data model. In particular, we will show that we can represent so-called exact views in UML/OCL, providing the means to capture the duality relation between federating and outsourcing.

Corporate Information

В условиях развития информационного общества (Knowledgeable society - KS) информационные системы стали неотъемлемой частью любой организации, даже самой малой, независимо от реализуемых ими бизнес-процессов. Такие информационные системы принято называть корпоративными информационными системами (КИС), или Corporate Information System (CIS). Особые требования при разработке КИС предъявляются к обеспечению их информационной безопасности, что может быть реализовано путем разработки КИС в защищенном исполнении. Технологии blockchain являются очень перспективными не только при применении их в традиционных сферах - производстве, сервисе, на транспорте, но и для решения проблем безопасности и информационной, в частности. Анализу данной проблемы и подходам к ее решению и посвящена данная статья. At present, in the context of the development of Knowledgeable society, information systems are at now an integral part of any organization, even the smallest, regardless of the business processes they implement. Such information systems are commonly referred to as Corporate Information Systems (CIS). Special requirements for the development of CIS are made to ensure their information security, which can be achieved by developing a protected version of the CIS. In this article is considered the analysis of this problem and approaches to its solution. Block Chain technologies are very promising not only when applying them in traditional spheres - manufacturing, service, transport, but also to solve security and information problems, in particular.

Original Approach

Workflow techniques have gained a lot of attention as a means to support advanced business applications such as cooperative information systems and process re-engineering but also as a means to integrate legacy systems. Inter-task dependencies, described separately from the other parts of the workflow, have been recognized as a valuable method in describing certain restrictions on the executions of workflows. In this paper, we study the issue of pre-analysing and enforcing inter-task dependencies. The protocol and the theory behind it are presented, along with examples and discussions on ways to improve the performance. The idea is to present the meaning of a dependency through an automaton which accepts the sequences of events tied by the dependency through an automaton which accepts the sequences of events tied by the dependency. We prune from the automata certain paths that cannot be followed due to the conflicting paths in other automata and record the feasible event sequences in a special data structure to be used during run-time. We show the correctness of the algorithms and also show that our run-time algorithm is linear, whereas the original approach suggested by MCC in Refs. 5 and 6 is exponential, when resolution of one event is concerned.

Intention To Continue

The Expectation-Confirmation Model of Information Systems Continuance (ECM-IS) explains antecedents that influence IS users’ behavior and affect their decision whether to continue or discontinue information system (IS) using. ECM-IS emphasizes differences between initial acceptance and IS continuance. For companies that deal with the design and software development, IS continuance is retaining of existing customers of product and services. This study extends the ECM-IS by accounting for unobserved heterogeneity. The Finite Mixture Partial Least Squares (FIMIX-PLS) methodology is applied for identification of distinctive customer segments. Segmentation of IS users was made on the basis of cognitive beliefs and affect influencing one’s intention to continue using IS and two different segments of users were derived. The first segment comprises 65.6%, and the other one 34.4% users. The ECM-IS explained 51.9% of IS continuance intention and 20.7% of satisfaction for the first segment, while for the second segment the ECM-IS explained 98.1% of IS continuance intention and 91.3% of satisfaction.
