No, IB doesn't have a "block" layout like file-based databases. Data are stored in pages which are allocated as required. The number of records per page is something less than page_size/record_size. There are different kinds of pages for different types of objects (table records, indices, etc.) Different pages for a particular table are stored anywhere, not in contiguous blocks. There is no notion of "physical structure" for things inside the database.
