Abstract. Often, XML documents stored in an XML database must be transformed by an XSL processor into a client-specific format before queries are submitted. In applications where X...
We investigate a higher-order query language that embeds operators of the positive relational algebra within the simply-typed λ-calculus. Our language allows one to succinctly de...
When building scalable systems that involve general-purpose computation and persistent data, object-oriented languages and relational databases are often essential components. Yet...
In this paper, still images are modeled by hierarchical tree structures and object relational graphs. These modeling concepts can be described naturally using XML schema. We intro...
