A database schema should consist of structures and semantic integrity constraints. Se mantic integrity constraints (SICs) are invariant restrictions on the static states of the stored data and the state transitions caused by the primitive operations: insertion, dele tion, or update. Traditionally, database design has been carried out on an ad hoc basis and focuses on structure and efficiency. Although the E-R model is the popular concep tual modelling tool, it contains few inherent SICs. Also, although the relational database model is the popular logical data model, a relational database in fourth or fifth normal form may still represent little of the data semantics. Most integrity checking is distributed to the application programs or transactions. This approach to enforcing integrity via the application software causes a number of problems. Recently, a number of systems have been developed for assisting the database design process. However, only a few of those systems try to help a database designer incorporate SICs in a database schema. Furthermore, current SIC representation languages in the literature cannot be used to represent precisely the necessary features for specifying declarative and operational semantics of a SIC, and no modelling tool is available to incorporate SICs. This research solves the above problems by presenting two models and one subsystem. The E-R-SIC model is a comprehensive modelling tool for helping a database designer in corporate SICs in a database schema. It is application domain-independent and suitable for implementation as part of an automated database design system. The SIC Repre sentation model is used to represent precisely these SICs. The SIC elicitation subsystem would verify these general SICs to a certain extent, decompose them into sub-SICs if necessary, and transform them into corresponding ones in the relational model. A database designer using these two modelling tools can describe more data semantics than with the widely used relational model. The proposed SIC elicitation subsystem can provide more modelling assistance for him (her) than current automated database design systems. / Business, Sauder School of / Graduate

Approved for public release; distribution is unlimited / The purpose of this research is to define a centralized database containing all necessary information related to the daily management in an industrial and commercial organization that is publicly owned and equipped with civil personality and financial autonomy. The system is composed of the following subsystems: o Subsystem "Human resource management" o Subsystem "Provisioning" o Subsystem "Financial, budgetary and accounting management" The three subsystems should be installed in a central site and at regional sites. Each site will have its own database. The central database will be supplied with the data, which come from the other sites at the end of the day or according to need via modems. It is necessary to develop a tool for remote database queries in order to accomplish this work. The platform on which the application must be executed is IBM-INFORMIX running on top of the WINDOWS operating system. The database will be a relational database. The framework used in the design and modeling consists of: o Object Oriented Analysis (OOA), which enables the development of high quality software by defining the problem structure. o The Delphi Language, which provides a robust development environment. The installation of the solution will be executed according to the following scenario: o Client/Server architecture with the object oriented development tool DELPHI. o The database will be installed on the central and regional servers. o The application will be installed on the end users' stations. o Data access will be through an open ODBC. This software will present an integrated solution that will provide centralized and accurate data, so that data will be used to derive the right decision at the best time. / Major, Tunisian Army
