  • the rationale for developing a corporate Data warehouse and the development of a Model for sharing Data in a Data warehouse environment
    OOIS, 1996
    Co-Authors: Kieran Curley, John Murphy
    Abstract:

    In this paper, we briefly examine the background to Data warehousing, and the rationale for implementing such a system. While there are several issues involved in the implementation of a Data warehouse project, this paper concentrates on the aspect of developing a corporate Data Model. A particular design process for an Enterprise Data Model proposed by [SCHE92] is examined. A Model is then presented for sharing Data across applications on a common platform, such as a Data warehouse, using the design process outlined. The basis of the argument in favour of Data sharing in this manner is firstly, interfaces will already have been defined between the operational Database systems and the Data warehouse. Secondly, all the Data from the operational systems already populate the Data warehouse tables. Thirdly, the process of preparing Data for migration to the Data warehouse will already have solved many of the problems associated with Enterprise Data Modeling, such as determining exactly where a Data item resides and what exactly it means. Finally, Data sharing can be achieved without having to develop micro-level Models of the whole Enterprise.

  • municipal gis and the Enterprise Data Model
    International Journal of Geographical Information Science, 1993
    Co-Authors: Raphael Sussma
    Abstract:

    Abstract The City of Scarborough, like many corporations, recently re-evaluated its information technology requirements. The decision was made to Model the City's needs in terms of activities and Data requirements, concentrating on the Municipal Data Model. First, a two year study was undertaken to understand the business activities of all the disparate components that make up the corporation. This study resulted in individual Information Resource Plans (IRP) for each department. A third year was spent in reconciling the many separate documents and creating a high-level Conceptual Data Model for a Corporate Information System. Of the thirteen broad Data groupings, four were assigned to the GIS Group for the design of Detailed Data Models and to populate the resultant Databases. The GIS Group, in fact, were to initiate the new Information System for the entire City. The Modelling sessions involved hundreds of users from the entire user community in small and large groups, in intensive entity-definition act...

  • Enterprise Data Model a study with reference to technical institution
    Web Information Systems Modeling, 2010
    Co-Authors: Shashidhar K Kini, D H Manjaiah
    Abstract:

    Businesses of all sizes and in different industries, as well as government agencies, are finding that they can realize significant benefits by implementing a Data warehouse. A Data warehouse provides the base for the powerful Data analysis techniques that are available today such as Data mining and multidimensional analysis, as well as the more traditional query and reporting. Having an Enterprise Data Model (EDM) available would be very helpful for the organization in developing Data warehouse Data Model. From EDM Technical institution can derive the general scope and understanding of the business requirements. The EDM would also let the organization to relate the Data elements and the physical design to a specific area of interest.
