A second course in database management
A second course in Database Management which stresses database design principles is described. The first course emphasizes database implementation utilizing both a relational and a CODASYL database management system. Students become familiar with the usage of a database management system as a implementation framework for databases. The second course provides the student with tools to perform logical database design and with techniques for converting logical designs into efficient physical implementations
Augmenting traditional conceptual models to accommodate XML structural constructs
Abstract. Although it is possible to present XML Schema graphically, such representations do not raise the level of abstraction for XML schemata in the same way traditional conceptual models raise the level of abstraction for data schemata. Traditional conceptual models, on the other hand, do not accommodate several XML Schema structures. Thus, there is a need to enrich traditional conceptual models with new XML Schema features. After establishing criteria for XML conceptual modeling, we propose an enrichment to represent the XML features missing in traditional models. We argue that our solution can be adapted generally for traditional conceptual models and show how it can be adapted for two popular conceptual models.
