CS-87-6 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science, School of Engineering and Technology Thesis (M.Sc.) - Asian Institute of Technology, 1987 An information system for a small-sized hotel is designed using the entity-relationship approach. This entity-relationship data model has been extended to include both the structural and dynamic properties of data. The design process is carried out in two main steps, logical design and physical design. Emphasis on the logical design phase is on the description of the behaviour of entities of the hotel information system at the conceptual level. In order to describe the behaviour of entities and their changes that take place over a period of time , the notion of instantiation and Petri Net diagrams are used. The hotel information system, designed to be installed on microcomputers, is implemented in Microsoft Cobol language. As the system is basically a file management system, each of the entities and their relationships have been translated into a conventional Cobol file with the attributes represented as the fields of the fil e. The hotel information system is interactive in nature.
