A large volume of data with complex structures is currently represented in GML (Geography Markup Language) for storing and exchanging geographic information. As the size and complexity of such documents and their schemas grow, techniques and rules for designing and creating such documents become indispensable. This paper introduces a method for mapping geographic conceptual specifications (defi...

This paper proposes an approach for translating an existing relational database (RDB) schema into relatively newer database (i.e., object-oriented, object-relational and XML) schemas, based on available standards. The approach is superior to existing proposals as it generates three different and equivalent target schemas. The solution takes an RDB as input, enriches its metadata representation ...

We provide mechanisms that facilitate database design based on a shrink wrap schema. A shrink wrap schema is a well-crafted, complete, global schema that represents an application. We develop the notion of concept schemas as a way to decompose shrink wrap schemas. A concept schema is a subset of an application schema that addresses one particular point of view in an application. To aid in shrin...

In this work we present an algorithm to generate a XML Schema for data whose structure is specified by the E-R conceptual model. The main goal of the translation process is to obtain a normalized schema preserving the structural information of the original one.
