Footnote

There is some debate over what exactly constitutes a native XML database. Bourret (2003) favors the wider definition; other authors such as the Butler Group (2002) restrict the use of the term to databases systems designed and built solely for storage and manipulation of XML. Two examples of the lauer (Tamino and eXist) are covered in detailed chapters here but also included in this section is the embedded XML database system, Berkeley DB XML, considered by makers Sleepycat Software to be "native" in that it is capable of storing XML natively but built an top of the Berkeley DB engine. To the uninitiated, the revelation that schemas and DTDs are not required by either Tamino or eXist might seem a little strange. Tamino implements "loose coupling" where the validation behavior can be set to "strict," "lax" (i.e., apply only to parts of a document) or "skip" (no checking), in eXist, schemas are simply optional. Many DTDs and schemas evolve as the XML documents are acquired and so these may adhere to slightly different schemas, thus the database should support queries an similar documents that do not share the same structune. In fact, because of the difficulties in mappings between XML and database (especially relational) schemas native XML databases are very useful for storage of semi-structured data, a point not made in either chapter. The chapter an embedded databases represents a "third way," being neither native nor of the XML-enabled relational type. These databases run inside purpose-written applications and are accessed via an API or similar, meaning that the application developer does not need to access database files at the operating system level but can rely an supplied routines to, for example, fetch and update database records. Thus, end-users do not use the databases directly; the applications do not usually include ad hoc end-user query tools. This property renders embedded databases unsuitable for a large number of situations and they have become very much a niche market but this market is growing rapidly. Embedded databases share an address space with the application so the overhead of calls to the server is reduced, they also confer advantages in that they are easier to deploy, manage and administer compared to a conventional client-server solution. This chapter is a very good introduction to the subject, primers an generic embedded databases and embedded XML databases are helpfully provided before the author moves to an overview of the Open Source Berkeley system. Building an embedded database application makes far greater demands an the software developer and the remainder of the chapter is devoted to consideration of these programming issues.
After several detailed examples of XML, Direen and Jones discuss sequence comparisons. The ability to create scored comparisons by such techniques as sequence alignment is fundamental to bioinformatics. For example, the function of a gene product may be inferred from similarity with a gene of known function but originating from a different organism and any information modeling method must facilitate such comparisons. One such comparison tool, BLAST utilizes a heuristic method has become the tool of choice for many years and is integrated into the NeoCore XMS (XML Management System) described herein. Any set of sequences that can be identified using an XPath query may thus become the targets of an embedded search. Again examples are given, though a BLASTp (protein) search is labeled as being BLASTn (nucleotide sequence) in one of them. Some variants of BLAST are computationally intensive, e.g., tBLASTx where a nucleotide sequence is dynamically translated in all six reading frames and compared against similarly translated database sequences. Though these variants are implemented in NeoCore XMS, it would be interesting to see runtimes for such comparisons. Obviously the utility of this and the other four quite specific examples will depend an your interest in the application area but two that are more research-oriented and general follow them. These chapters (on using XML with inductive databases and an XML warehouses) are both readable critical reviews of their respective subject areas. For those involved in the implementation of performance-critical applications an examination of benchmark results is mandatory, however very few would examine the benchmark tests themselves. The picture that emerges from this section is that no single set is comprehensive and that some functionalities are not addressed by any available benchmark. As always, there is no Substitute for an intimate knowledge of your data and how it is used. In a direct comparison of an XML-enabled and a native XML database system (unfortunately neither is named), the authors conclude that though the native system has the edge in handling large documents this comes at the expense of increasing index and data file size. The need to use legacy data and software will certainly favor the all-pervasive XML-enabled RDBMS such as Oracle 9i and IBM's DB2. Of more general utility is the chapter by Schmauch and Fellhauer comparing the approaches used by database systems for the storing of XML documents. Many of the limitations of current XML-handling systems may be traced to problems caused by the semi-structured nature of the documents and while the authors have no panacea, the chapter forms a useful discussion of the issues and even raises the ugly prospect that a return to the drawing board may be unavoidable. The book concludes with an appraisal of the current status of XML by the editors that perhaps focuses a little too little an the database side but overall I believe this book to be very useful indeed. Some of the indexing is a little idiosyncratic, for example some tags used in the examples are indexed (perhaps a separate examples index would be better) and Ron Bourret's excellent web site might be better placed under "Bourret" rather than under "Ron" but this doesn't really detract from the book's qualities. The broad spectrum and careful balance of theory and practice is a combination that both database and XML professionals will find valuable."

- E-Rights. Bürgerrechte in der Informationsgesellschaft Eine breite Front neuer Bürgerrechtsbewegungen versucht die neu entstandenen Freiräume im Netz gegen staatliche und ökonomische Kontrollversuche zu verteidigen. Das Kapitel skizziert den Verlauf dieser Front, markiert die Teilnehmer und sagt, mit welchem rasanten Tempo staatliche Akteure Weichenstellungen für das kommende 21. Jahrhundert vornehmen. Wer entscheidet in Zukunft über den Umgang mit Wissen, Copyright und Zensur? Welche Bürgerrechte stehen zur Disposition? Schulzki-Haddouti, C.: Bürgerrechte im Netz.

Die Ökonomie des Wissens Wissensmanagement und Data-Mining versprechen Unternehmen die aktive Nutzung brachliegender Ressourcen. Wissen gilt zumindest in den ökonomischen Diskursen als grundlegender Produktionsfaktor. Wie sieht es hier in der Praxis aus? Unternehmen schauen aber nicht nur nach innen, sondern auch über den Tellerrand: Die (legale und illegale) Beschaffung von Informationen über den Markt, die Wettbewerber und das Image der eigenen Firma wird zur täglichen Aufgabe.

Massenmedien online Klassische Medien wie Fernsehen und Zeitung prägen bis heute das Bild des Alltags. Sie schaffen gemeinsames Wissen, transportieren kollektive Wertvorstellungen und neue Wissensmuster. Mit dem Gang ins Internet wagen sich die Massenmedien auf ein fremdes Terrain. Viele ehrgeizige Projekte können als gescheitert gelten, andere haben sich wider Erwarten durchgesetzt. Was ist wirklich neu an Online-Medien?

Footnote

Some of the pieces are more captivating than others and less "how-to" in nature, providing contextual discussions as well as pragmatic advice. For example, Darlene Fichter's "Blogging Your Life Away" is an interesting discussion about creating and maintaining blogs. (For those unfamiliar with the term, blogs are frequently updated Web pages that ]ist thematically tied annotated links or lists, such as a blog of "Great Websites of the Week" or of "Fun Things to Do This Month in Patterson, New Jersey.") Fichter's article includes descriptions of sample blogs and a comparison of commercially available blog creation software. Another article of note is Kelly Broughton's detailed account of her library's experiences in initiating Web-based reference in an academic library. "Our Experiment in Online Real-Time Reference" details the decisions and issues that the Jerome Library staff at Bowling Green State University faced in setting up a chat reference service. It might be useful to those finding themselves in the same situation. This volume is at its best when it eschews pragmatic information and delves into the deeper, less ephemeral libraryrelated issues created by the rise of the Internet and of the Web. One of the most thought-provoking topics covered is the issue of "the serials pricing crisis," or the increase in subscription prices to journals that publish scholarly work. The pros and cons of moving toward a more free-access Web-based system for the dissemination of peer-reviewed material and of using university Web sites to house scholars' other works are discussed. However, deeper discussions such as these are few, leaving the volume subject to rapid aging, and leaving it with an audience limited to librarians looking for fast technological fixes."
