SQL (Structured Query Language) is intended to liberate users from the complex syntax, complex semantics and complex memory management that would be required of a procedural approach to relational database manipulation, and so allow users to concentrate ...

The paper describes our experience in teaching a database systems module that is compulsory to all final year computing and information systems students with a diverse range of backgrounds and technical abilities. This challenge has driven the attempt ...

Two international collaborative developments, involving the teaching of databases to international students, has provided a practical basis for this paper on internationalisation in databases. The conclusion drawn is that the curriculum, teaching and ...

As part of the Workshop on Teaching, Learning and Assessment in Databases, there will be a discussion centred on the challenges of introducing cutting edge technology into industry, and the impact of database teaching on a real world project. The ...

This paper describes a course in data warehouse design that includes conceptual, logical, and physical design research. The instructional modes and assessment techniques are described and illustrated. The scope of the course is given via a discussion of ...

The purpose of this paper is to share innovative teaching methods at Leeds Metropolitan University in the Innovation North Faculty of Information and Technology (INN Faculty). The paper provides an account of the use of integrated assessment with a ...

In this paper we report ongoing work in the development of diagram interpretation and assessment applied to entity-relationship diagrams (ERDs). We report on our development of an automated marking tool and the results of two large-scale experiments ...

It is always a challenge to prepare lectures, student projects and assignments for courses on active research topics. However, in order to make a study program more attractive to the students and at the same time to support research, offering such ...

While specification languages for integrity constraints for XML data have been considered in the literature, actual technologies and methodologies for checking and maintaining integrity are still in their infancy. Triggers, or active rules, which are ...

XML element retrieval aims at finding the best elements satisfying a user's information need. Elements spanning only a few words, like titles or italicized phrases, are not in themselves useful results, but they can support the relevance of their ...

Query performance issues over semi-structured data have led to the emergence of materialised XML views as a means of restricting the data structure processed by a query. However preserving the conventional representation of such views remains a ...

Design methodologies for web applications usually specify the functionality using some kind of workflow model, since the processes supported by web sites such as those used for e-commerce and information dissemination can be expressed in terms of the ...

This paper presents WordRank, a new page ranking system, which exploits similarity between interconnected pages. WordRank introduces the model of the "biased surfer' which is based on the following assumption: "the visitor of a web page tends to visit ...

This paper explores the pitfalls of information disclosure in an e-commerce context. Many unwary and unaware e-customers fall into this trap. We explore current efforts to give the user control over disclosure of sensitive information. We propose a ...

Internet applications are deployed over increasingly complex collections of devices located in network topologies of increasing variety. We seek to develop a complete development environment in which such applications can be designed, implemented and ...

Labels and datatypes are together the most important factors in identifying the best correspondences in matching XML Schemas. Besides label matching, datatype matching is also necessary since XML Schema is designed for datatype definitions for XML ...

The XQuery language is the standard query language for XML. The result of XQuery queries are typically XML documents in other formats. We introduce the term output schemas of an XQuery query, which represents those schemas, to which the resultant XML ...

XML query processing involves searching an XML document and returning results that satisfy a query while choosing the best method for the particular query and document. In this paper we develop a method called Binding Hash (BH) that performs a subset of ...
