Catherine McHugh Engstrom and Kevin Kruger’s book reveals how the widespread use of technology is reshaping the higher education and student affairs landscape. Just the arcana of the Internet leads one to conclude that, like Dorothy and Toto, "We’re not in Kansas anymore." Concepts like structured query languages, intellectual property infringement, cybernars, technology clusters, computer use policies, MUDs (multi-user domains), MOOs (multi-user domains, object-oriented) and Mushes (multi-user shared hallucinations) require that student affairs educators reconsider their roles and purposes on the college campus. The authors and editors of the sourcebook have done an admirable job of guiding the reader through this quickly shifting landscape and present a thorough analysis of the challenges and opportunities that information technology offers to student affairs educators.

Nowadays, the data are available in a variety of formats such as relational data-base tables, xml files, rdf files or simply text files. Database systems have their own query languages and tools for the manipulation of data. On the other hand, most of todays applications are created in languages based on the object-oriented paradigm. From the level of the programming language it is important to use different sources of data in a uniform manner. The paper discusses the elements of the various query languages such as SQL XQuery or SPARQL. And then shows the capabilities of LINQ and its role in the creation of abstract data access layer. Then the possibilities of LINQ extension are discussed. As the example, design and implementation of LINQ provider for Allegro is presented.
