I would like to know if my PPA will be open to view by anyone who searches in a database. If it's so, where is this database on the USPTO website?

According to the USPTO:

Further, because a PPA is not made public unless its application number is noted in a later-published application or patent, the failure by an applicant to file a nonprovisional application based on his/her PPA will not lead to public disclosure of his/her invention.
