1. IT – som værktøj Bent Thomsen Institut for Datalogi Aalborg Universitet

2. What have we covered? A bit about IT history Operating systems (Unix) Some (hopefully) useful applications –Browsers, IM, text processing (LaTeX) Networks and the Internet (HTML) Systems for engineering calculations –MATLAB and Excel Database systems –Excel and Access Programming (JavaScript and PHP)

3. What haven’t we covered? Wireless computing New display technologies Web Services Grid computing

4. IT today and tommorow

5. The Mobile Student Register for courses Always available resources –“e-textbooks” –“e-notes” –“e-references” Virtual Classroom

6. 1. Natural Language (Spoken) Command 2. Raw Speech Data 3. Server-Side Processing 4. Processed Data

7. Natural Computing for Humans

9. Web Service A Web service is like a Web site without a user interface, that serves programs instead of people. Instead of getting requests from browsers and returning web pages in response, a web service: –receives a request formatted in XML from an application, –performs a task, –and returns an XML-formatted response. Web Services are delivered using open industry standards

10. Company A Consumers, Partners MobileEmployees Company B Customers Partners Suppliers Consumers, Partners MobileEmployees The Virtual Enterprise Slide from Microsoft.Net presentation

11. Microsoft’s.NET

12. Sun One Architecture Support major standards initiatives such as SOAP, J2EE[tm], UDDI, LDAP, and ebXML to make it ready for developers who want to take advantage of the Services on Demand vision

13. Vision for web services Services to be described in WSDL Services to be announced via UDDI Data to be exchanged via XML Protocols are HTTP and SOAP Systems are developed in Java or C# or PhP

14. Beyond the Net, lies the Grid. The Net allows users everywhere to share information. The Grid will allow users to share raw computing power. »It’s under construction.

15. What is a Grid? persistent networked environments integrating geographically distributed supercomputers, large databases, and high end instruments coordinated resource sharing and problem solving in dynamic virtual organizations

16. It’s for real. Used to construct: collaborative engineering systems real-time instrument control systems problem solving environments to perform record-setting scientific simulations.

18. DOE X-ray grand challenge: ANL, USC/ISI, NIST, U.Chicago tomographic reconstruction real-time collection wide-area dissemination desktop & VR clients with shared controls Advanced Photon Source Online Access to Scientific Instruments archival storage

19. You don’t have to be a computer scientist…

20. Building on the Internet, the WWW Uniform naming A seamless, scalable information service A powerful new meta-data language: XML –SOAP - simple object access protocol - Uses XML for message encoding, HTTP for protocol. XML-RPC may become standard mechanism for Grid Services.
