i also thought its relative to database but ultimately it also depends on the data structure & Algorithms used by database to implement the particularly query. The simpler implementation of this service is to store, in a database table, a data pair (id, url) where your id has the autoincrement option, e.g.
1 -> www.facebook.com 2 -> www.otherurl.com/path/complete/to/the/page.php 3 -> ... so on So when a user ask for http://tinyurlservice.com/1 you simply do a select into your table (select url from urlstable where id = '1') and then you do a redirect to that url. You could refine this, looking before if a certain url was already 'tinyurled' (so you prevent multiple insertions of the same url), you could add a date field in your table and delete the older entries with a stored procedure or with a cronjob or with an admin panel... and so on. 1 have another approach using temp. array of all chars that a url can contains will explorer later.. Hope this will be useful for you., Correct me if anything wrong Thanks Shashank CSE,BIT Mesra -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
