I am trying to build a small web application. The application is to store the bookmarks and its tags.

bookmark: http://www.javaworld.com
tags: java, programming

bookmark: http://www.jquery.com

tags: java,webapps

now my search criteria is based on tags. If a user search’s for java it should give all the bookmarks he stored with java. here both http://www.javaworld.com and http://www.jquery.com must be shown.

my database tables looks like this

Users ( UID, Uname, Password)

Bookmarks( BID, UID, bookmark_url,tag1,tag2,tag3,tag4,tag5)

or

Bookmarks( BID,UID,bookmark)

Tags(TID,BID,Tagname)

here BID and TID are surrogate keys.

please suggest the better way to solve this problem considering the scenario i gave..

    Why not make something similar like on Stackoverflow? Tags are “global” and not bound to a single bookmark.
    Allows you to define tags without having to define bookmarks beforehand, which improves flexibility. Also limiting to 5 tags as in your first solution is not a good idea either.

    Separating them like follows allows you to run aggregrate functions better (making tag clouds) and you can use the tag table to display tags in a checkbox/multiple select for new bookmarks better. It’d feel awkward if they are bound to another bookmark already.

    Table: User [UID, Uname, PW]

Table: Bookmark [BID, UID, url]

Table: Tag [TID, Tagname]

Table: Bookmark_Tag [BID, TID]
