Hi All,

We will be carrying out the largest HIV vaccine clinical trial (a US Department of Defense project). US Food and Drug Administration has very strong requirements concerning electronic signature if we want our electronic records to be accepted by FDA. I am doing system requirements analysis at this moment and have very little knowledge on electronic signature. I would really appreciate explanations on what an electronic signature is, how can it be implemented in a database (especially in an VFP + MS SQL Server based application) and where can I find more information. Thank you!
