Die Brüsseler Kommission hofft, mit massiver Förderung die unterschiedlichen nationalen eID-Systeme der Mitgliedsländer aus ihrem Inseldasein herauszuholen.
VIAF ist ein Gemeinschaftsprojekt von Nationalbibliotheken, das von OCLC implementiert und gehosted wird. Projektziel ist es, eine Kostensenkung bibliothekarischer Normdaten bei gleichzeitiger Steigerung ihres Nutzens zu erreichen, indem die nationalen Normdateien abgeglichen und verlinkt werden und die verlinkten Daten im Web zugänglich gemacht werden.
Der Großausfall in der Amazon-Wolke sei nur die Spitze des Eisbergs an Problemen, die Cloud-Computing mit sich bringt, sagte Internetpionier Dave Farber zu ORF.at. Am Montag gab erneut ein Cloud-Anbieter das Geschäftsfeld auf.
In today's humongous database systems, clarity may be relaxed, but business needs can still be met.
Pat Helland, Microsoft
Classic database systems offer crisp answers for a relatively small amount of data. These systems hold their data in one or a relatively small number of computers. With a tightly defined schema and transactional consistency, the results returned from queries are crisp and accurate.
New systems have humongous amounts of data content, change rates, and querying rates and take lots of computers to hold and process. The data quality and meaning are fuzzy. The schema, if present, is likely to vary across the data. The origin of the data may be suspect, and its staleness may vary.
Today's data systems coalesce data from many sources. The Internet, B2B, and enterprise application integration (EAI) combine data from different places. No computer is an island. This large amount of interconnectivity and interdependency has led to a relaxation of many database principles. Let's consider the ways in which today's answers differ from what we used to expect.
