The development of applying database management applications is currently underway within Geographical Information Systems (GIS) applications in the Sultanate of Oman.The establishment of a national database management system in Oman is considered as the backbone that is required within the Geographic Information System project in Oman. The principal of the GIS project in Oman was built upon unifying the used software packages over the sultanate which is ARC/INFO as GIS Package and ORACLE as database management software. These packages are used within the different participating Ministries in the GIS project in Oman.The participating ministries will handle information that are shared between them. The shared information among the different ministries is the attributed data which is defined as descriptive information extracted from geographic features that usually existed on the topographic maps and the ministries maps (utility maps). The map features can be classified into different layers according to the principles of ARC/INFO GIS Package. Accordingly, the main objectives of this research paper is to explain the technique proposed for establishing a national database management system that can handle and manage the shared information amongst the participating ministries in the project. The proposed database design will be made using the ORACLE database management system. Moreover, the paper will handle a proposed idea for linking the geographic map layers with the corresponding attributed database in order to create Geographic Information System applications. As a Conclusion, it is Proposed that all the government GIS departments in the Sultanate will share the same information within a unique national database management which can be considered one of the major benefits in applying database management in the field of Geographic Information Systems.

Database Management System

The chapter presents the geographic information systems. A geographic information system (GIS) is a computer system that allows various sources to gather and organize, manage, analyze and combine, develop, and present geographically located information contributing in particular to the management from space. A geographic information system is also a database management system for entering, storing, retrieving, querying, analyzing, and displaying localized data. It is a set of data located in space, structured so that it can conveniently extract syntheses useful to the decision.

Legacy Information Systems

Database reverse engineering consists of recovering the abstract descriptions of files and databases of legacy information systems. A legacy information system can be defined as a “data-intensive application, such as [a] business system based on hundreds or thousands of data files (or tables), that significantly resists modifications and changes” (Brodie & Stonebraker, 1995). The objective of database reverse engineering is to recover the logical and conceptual descriptions, or schemas, of the permanent data of a legacy information system, that is, its database, be it implemented as a set of files or through an actual database management system.

Information systems must be protected from unauthorized access. Authorization has been studied extensively as the main form ofpreserving the security of databases. Every database management system provides a sophisticated set of options aimed at protecting the database from unauthorized access. An important practical problem is how to take advantage of the database security options to ensure that a user is permitted to access the database through the application program but may not be allowed to access the database directly via database query tools. A related issue is how to extend the user privileges on the client part of the application so that only authorized GUI controls are available to the user. In this paper we propose a model for the design of necessary authorization settings into both the client and the server parts of a database application. The settings are stored in an Authorization Database (ADB) to which the program connects to customize itself for the current user. The customization is based on an application role granted to the user. An application role is activated for a connection (user session). After the database server authenticates the user, the user login to the application role can be transparently obtained by the application from the ADB.

Project Quality

The development of information systems is a difficult process that often ends in failing to meet the project's initial goals. Typical outcomes for information systems development projects include delivering promised products & services on time and within budget. These pressures are now compounded by the use of virtual teams that present a new set of challenges related to the cohesion, organization, and functioning of the team process. Specifically, virtual teams must contend with problems in team formation, the organizational environment in which the team operates, and the technology used for collaboration and communication. As more organizations use virtual teams, these problems present real and pressing obstacles to the successful completion of database systems development. The goal of the study was to determine whether leadership type, transformational, transactional, or management-by-exception was significantly related to leadership effectiveness in a virtual team tasked with developing a database management system. This study targeted millennial students at the Maine Business School who were assigned to virtual teams tasked with developing a database management system. Specifically, this study sought to answer three hypotheses: 1) what is the effect of leadership type, as self-reported through the Multifactor Leadership Questionnaire on the quality of completed team projects?; 2) What is the impact of type of leadership on virtual team effectiveness as measured by the Virtual Teams Survey?; and, 3) Are there interactions between leadership style and virtual team effectiveness on the quality and uniqueness of the completed team project? Findings suggest leadership style and virtual team effectiveness did predict project quality, Transformational and Management-by-exception leadership styles had a negative relationship with virtual team effectiveness. Findings further suggest that Transactional leadership style influenced project quality directly, while transformational and management-by-exception styles influenced project quality indirectly through their direct influence on virtual team effectiveness. These findings suggest that traditionally effective leadership types do not work well for Millennial Generation teams in virtual environments

The Subject

The article discusses the possibilities of using modeling tools at the stages of database design. Database design is one of the most complex and crucial tasks associated with the creation of an automated information system. As a result of solving this problem, the content of the database should be determined, an effective way for organizing data for all its future users, and data management tools. The main goal of this stage is to develop such a database scheme that it includes the necessary and sufficient data on information objects, their properties and relationships in accordance with the objects of the subject area and the processes of their transformation. The authors present the results of using modeling tools to solve the problems of the database design stage. Creating models is considered from the point of view of three-circuit architecture, the main principle of which is abstraction. To display the levels of data presentation, three related models have been developed: an external data model that displays the representations of each type of user existing in the organization (description of the subject area); a conceptual data model that displays a logical (or generalized) idea of data, independent of the type of database management system selected; an internal data model that displays the conceptual diagram in a specific way that is understandable to the selected target database management system. As an example of a subject area, the activity of a school of foreign languages is considered, namely, the registration of students in a school. The main problem is the large amount of information that is processed manually: paper forms of clients are drawn up, reports on the implementation of work are manually generated and filled out. It is necessary to develop a draft database for the registration of students of a school of foreign languages and to further implement it in the environment of the selected database management system.
