I decided to take a shot at it.
The way I see it your original talks about some sort of statistical data contained in the database, therefore I use statistics' terminology.

Other (less statistical way) of saying it: Current situation, development and promulgation trends of terrorism.

You can find examples for "dynamics of terrorism" here: http://www.google.com/search?hl=en&rls=com.microsoft:en-US:I...

The process supports timely promulgation of terrorism information at the appropriate level of classification to ISE participants.http://www.google.com/url?sa=t&source=web&cd=18&ved=0CDAQFjA...

(30) He observed that the promulgation of terrorism by various organisations and the economic crisis faced by many of these states makes them nascent nurseries for terrorism. http://webcache.googleusercontent.com/search?q=cache:JnjqUj-...

[...] it would detract from the efforts to reduce the promulgation of terrorism from al Qeada in Afghanistan.

Just saw another way of translating "dynamics" by our colleague, Vladimir Shelukhin here: http://www.proz.com/kudoz/english_to_russian/marketing_marke...

So here's another version for you: ***status, shifts and trends in the spread (promulgation) of terrorism***.
