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.

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.

A Geographic Information System (GIS) is a computerized database management system for accumulating, storage, retrieval, analysis, and display spatial data. In general, GIS contains two broad categories of information, geo-referenced spatial data and attribute data. Geo-referenced spatial data define objects that have an orientation and relationship in two or three-dimensional space, while attribute data is qualitative data that can be counted for recording and analysis. The main aim of this research is to reveal the role of GIS technology in the enhancement of bridge maintenance management system components such as the output results, and make it more interpretable through dynamic colour coding and more sophisticated visualization techniques than the conventional tabular data format. To achieve the main objective of this research, two study areas have been chosen: the old constructionbridge (Al-Qadisiyah bridge) and the newly constructed bridge (Barboty bridge). Both of them are in Al-Muthanna city \ Iraq. The data collection process was achieved in two stages: the first stage is providing a georeferenced satellite image for each study area for the purpose of producing a two-dimensional map. The second stage includes the field surveying process by total station and level instruments. GIS have been used to create a comprehensive database (Geodatabase) for both study areas. Geostatistical analysis was carried out in which the settlement areas of both study areas were defined by producing a colour image. The statistical tables for these analyses showed that the highest decline in the elevation reached at Al-Qadisiyah bridge to 19 mm in the middle of the bridge which is coloured as a red areas. On the other hand, it was found that the highest decline in the elevation of the Barboty bridge is 16 mm in the last part of steel space which is also coloured as a red areas.

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.

Geographic information systems emerged in the 1970s and have become a significant decision-making tool as their capabilities have been enhanced. This chapter discusses various GIS applications and highlights issues that public managers should consider when evaluating implementation of a geographic information system. GIS applications provide benefits at the planning level by producing maps efficiently, and at the management decision-making level through an ability to geographically display important information for policy-level decisions. While GIS analysis can be a powerful tool, there are a number of issues that pubic managers should consider in order to achieve effective implementation and use of geographic information systems.
