randomizing course branches and saving assessment data

Hi,

I am a newbie to Captivate and eLearning design. I am a programmer by my previous training.

As a final project in my Instructional Design degree, I am planning to build an online course with an integrated controlled experiment on learning styles and built-in assessments.

During the experiment, learners will be randomly assigned different learning styles for the same material.

Question:

Does Captivate provide flexibility to choose randomly study material, possibly based on user ID?

Moreover, I want to store data after learners pass several assessments. Saved data will help to measure retention of the material studied and to evaluate the efficacy of the learning styles.

Question:

Does Captivate provide the flexibility to record data for every learner? I will probably need to capture user IDs, type of the material studied, assessment results, and maybe the time it took them to answer questions in the assessment.

I am wondering where I can read how to do the above.

Thanks.

Viktor.
