    The administrative window into the integrated DBMS

    Get PDF
    A good office automation system manned by a team of facilitators seeking opportunities to serve end users could go a long way toward defining a DBMS that serves management. The problems of DBMS organization, alternative approaches to solving some of the major problems, problems that may have no solution, and how office automation fits into the development of the manager's management information system are discussed

    Federation views as a basis for querying and updating database federations

    This paper addresses the problem of how to query and update so-called database federations. A database federation provides for tight coupling of a collection of heterogeneous component databases into a global integrated system. This problem of querying and updating a database federation is tackled by describing a logical architecture and a general semantic framework for precise specification of such database federations, with the aim to provide a basis for implementing a federation by means of relational database views. Our approach to database federations is based on the UML/OCL data model, and aims at the integration of the underlying database schemas of the component legacy systems to a separate, newly defined integrated database schema. One of the central notions in database modelling and in constraint specifications is the notion of a database view, which closely corresponds to the notion of derived class in UML. We will employ OCL (version 2.0) and the notion of derived class as a means to treat (inter-)database constraints and database views in a federated context. Our approach to coupling component databases into a global, integrated system is based on mediation. The first objective of our paper is to demonstrate that our particular mediating system integrates component schemas without loss of constraint information. The second objective is to show that the concept of relational database view provides a sound basis for actual implementation of database federations, both for querying and updating purposes.

    A Citation-Based Ranking of Strategic Management Journals

    Get PDF
    Rankings of strategy journals are important for authors, readers, and promotion and tenure committees. We present several rankings, based either on the number of articles that cited the journal or the per-article impact. Our analyses cover various periods between 1991 and 2006, for most of which the Strategic Management Journal was in first place and Journal of Economics & Management Strategy (JEMS) second, although JEMS ranked first in certain instances. Long Range Planning and Technology Analysis & Strategic Management also achieve a top position. Strategic Organization makes an impressive entry and achieves a top position in 2003-2006.Journal rankings; Citation analysis; Strategic Management; Academic impact; Strategy

    Economic security & reconstruction: utility, history and practice in post-conflict environments

    Please consult the paper edition of this thesis to read. It is available on the 5th Floor of the Library at Call Number: Z 9999 P65 D53 2007This paper argues that the historical origins of the modem nation-state structure are based in part on economic processes, which give contemporary nation-states a specifically economic set of features and characteristics. As a result, there is a real but little understood economic security component of international relations that is increasingly recognized by competing schools of academic thought, including the realist school, which has historically been hesitant to acknowledge such issues as a feature of the international system. The paper further suggests that an understanding of economic security has significant implications for the theory and practice of post-conflict reconstruction in contemporary nation-states. However, CUlTent reconstruction practice fails to explicitly acknowledge the reality of the economic security dimension, although it sometimes recognizes the role of economic security in an implicit way, resulting in a disturbing separation of policy and practice that weakens overall reconstruction efforts. A stronger understanding of the economic security paradigm allows the international community to identify and adopt those development and reconstruction practices that are most effective in the field, and thereby offer the greatest opportunities to strengthen and stabilize state security in postconflict environments. The paper concludes by identifying and endorsing specific reconstruction strategies and practices that, by incorporating an understanding of the economic security paradigm, are best positioned to enhance the security-building process in post-conflict environments
