    Currently, information technology has gained interests in various ways and has been used by almost all businesses The development of information technology has affected wider areas in every industry, both private and public Information systems are beneficial to the management of the organization or agency They allow users in each level to access information and use that information quickly, allow executives to use data from the information systems in strategic management of the organization correctly, help in the monitoring and controlling of the operation clearly and accurately, help analyze and fix problems that occur, and reduce costs and working time It can be concluded that any agency or organization that makes use of information systems in the operation and management at each level of the organization is moving in the right direction However, the information systems must be based on the development of systems that are accurate, reliable, and on the cutting edge of technology Saving and credit cooperative is another kind of agency that emphasizes on service and management by information systems, since the operation needs accurate information and cannot tolerate database update anomalies, because it is a system that is related to financial management. Information systems that have been used are either developed specifically for particular organizations or as a software package The database for the system must have the best structure and integrity constraints clearly modelled on a conceptual schema Since the use of the Entity Relationship Model ER Model cannot always guarantee the fifth normal form 5NF relational database schema, another conceptual schema model is required The NIAMORM Nijjsens Information Analysis Methodology Object Role Model which guarantee the Optimal Normal Form ONF is used instead The ONF is defined as the 5NF which has the smallest number of tables.

    Applying conceptual schema to the design of knowledge management for safety activities

    At present, both small and medium size (SME) and large industries utilize machinery and modern production facilities to gain production advantages. Facilities, environment and safety management become a serious challenge. In developing countries, many workers have minimum education backgrounds and not all of them are safety conscious. Even workers with higher education sometimes have problems dealing with advanced complex equipments. High staff changing rate is also a major cause of the challenge. Knowledge management (KM) is a supplementary solution to the challenge. This paper presents a knowledge management system for safety activities and the application of the NIAM conceptual schema model to design the repository database of the system. The application of KM for safety helps both the management and qualified staff collects and organize explicit and tacit knowledge on the safety issues so that they and less experienced workers can utilize the knowledge to create better working environment. A web-based software tool has been developed to promote two way communications that finally leads to higher safety awareness, lower-risk environment and in-time accident management.
