today, ecotourism is a major tourist activity around the world. it is based on environment potential through which suitable utilization and conservation of sites under management practices including considering accurate planning, potential, and peoples’ preferences are realized. the present study was conducted to determine people’s recreational preferences using questionnaires to evaluate the e...

Hand-drawn diagrams are frequently used as the first visualization of a model. Converting these preliminary diagrams into a specific formal format is time consuming. Computer based sketch-tools can offer support during the informal sketching stage and automatic conversion to formal representations. Entity Relationship diagrams are particularly difficult to convert because of their characteristi...

The present paper addresses a general diagram to investigate the real-time parallel computation mechanism in the brain, using an idea of “Gantt chart.” This diagram explicitly represents the temporal relationship between the computations running in various functional modules in the brain, and helps us to understand how the brain computation proceeds along the time. The author illustrates how we...

this research discusses the process of designing a conceptual model for a new information system, i.e. electronic document management system. the new system is designed for an educational institute (itvhe) whose managers are the research population. the research methodology is based on structured analysis and design methodology (ssadm). in the end, the new system proposed using a data flow diag...

Designing and building a knowledge management system involves ensuring that the right facts can be called upon to answer the question at hand, and coordinating a number of disparate resources. Modelling such resources can be problematical as there is currently no formalism that can represent the nature of the dataseeking process at a conceptual level. We introduce the functional entity (FE), an...
