- History Places: A Case Study for Relational Database and Information Retrieval System Design Hendry, David G. History Case Studies Student Projects Teamwork Cooperative Learning Class Activities Web Sites Databases Programming Computer Science Education Database Design Database Management Systems Electronic Libraries Information Retrieval This article presents a project-based case study that was developed for students with diverse backgrounds and varied inclinations for engaging technical topics. The project, called History Places, requires that student teams develop a vision for a kind of digital library, propose a conceptual model, and use the model to derive a logical model and information retrieval specification. From these two design representations, students implement a data-driven Web site that enables users to browse content and search by exact and best-match queries. The project brief contains a set of general requirements that promote creative solutions, while also bounding the complexity of the solution space. The article includes teaching notes and a conceptual model, expressed as an enhanced entity-relationship model in UML. The model, consisting of approximately ten entities, contains binary, unary, ternary, and specialization/generalization relationships. The article concludes with some reflections based on the experiences of using this project in six classes over four years.
