Most folks will have used a least a little declarative programming if they're ever interacting with a DB - you can drop out into procedural land using cursors and functions but SQL really shines when you tell your DBMS what you want and let it figure out the details itself. Building complex logic ins declarative languages is one of the most rewarding things I've ever done. I tend to prefer a strong focus on type transformation when approaching a problem in any paradigm (I'd tend to read "Get the user's name" as "Create a transformation from a User ID to the User's Name and then cast the value") but just putting all the blocks for declarative programming together and then saying "Now, go!" is quite satisfying. |
