14. 142015-08-28 Access to Internet There were lucky ones.......and not so lucky ones.

15. 152015-08-28 Architecture GeoLog architecture

16. 162015-08-28 Technologies (I) Why Java? –Everybody familiar Why Spring framework? –Enterprise capabilities –Programming to interfaces –POJOs – high testability –Out of the box features Acegi security (web authentication and authorization), transactions, abstractions

17. 172015-08-28 Technologies (II) Why JSP? –Similar to PHP Why Hibernate? –ORM – working with objects and not SQL –Support for most databases –Caching capabilities

18. 182015-08-28 What is done? (I) Requirements fulfilled 4 user interfaces Initial requirements52 Added requirements10 Dropped requirements0 Total requirements62

19. 192015-08-28 What is done? (II) Requirements fulfilled –USERS ADMINISTRATION Multiple users privileges (SA, CA, user guest) Safe registering user method User promotion to CA for one or more specific categories Banning/unbanning users Ensure privileged users Scheduled deleting of non-activated users...

20. 202015-08-28 What is done? (III) Requirements fulfilled –CONTENT ADMINISTRATION Category hierarchy Adding new categories Adding new locations, articles, comments Location, article, comment refusing/approving Location popularity ranking Locations visible in Google Earth

21. 212015-08-28 What is done? (IV) Requirements fulfilled –CONTENT ADMINISTRATION News publishing Reporting inappropriate content Locations search by name, by category or on Google Map Deleting published news Uploading images to local file system...

22. 222015-08-28 What is done? (V) Requirements fulfilled –RANKING Ranking users and locations Articles from privileged users publishes immediately Location/article/comment refusing decreases user’s rank Better ranked locations are visible from higher altitudes in Google Earth Voting restrictions; user can vote for an article only once

23. 232015-08-28 What is done? (VI) Requirements fulfilled –SYSTEM ADMINISTRATION Changing system properties –Changing boundary rank for privileged user –Changing min. number of articles for privileged user Changing SMTP properties

24. 242015-08-28 What is done? (VII) Requirements fulfilled –WEB Using CSS for easier web design changes Presenting locations using “Google maps” Scalability when listing users, comments, news (pagination) Printing style sheet

25. 252015-08-28 Problems Category hierarchy –Understandnig –Presenting category tree on web tier Technical problems –Virtual server – Fedora 4 System management, memory, web server crashes, GMaps API key Lack of time One team member has dropped of

26. 262015-08-28 Our experiences...(I) Distributed development: –communication is very important –cultural differences Real working experience –deadlines –reports and status presentations –planning project cost Team work A VERY USEFUL EXPERIENCEBut after all – A VERY USEFUL EXPERIENCE

27. 272015-08-28 Our experiences...(II) What does the team say? –Interesting and absorbing experience in software development and communication. –Bitter sweet Symphony –I worked like crazy, but at least now everybody is jelaous that I am in Sweden –Don’t try this at home –Intense concentration of different technology experts with variable working habits and different cultural backgrounds is very explosive mixture. DSD project should be presented to students as a heavy box with a big sign "Handle with care, this side up" on it. You can never know when it's going to loose tracks and start to behave as C3H5(NO3)3.

28. 282015-08-28 Our experiences...(III) How we finished GeoLog? –These are two of our developers working hard
