            GhaiWhat is Data Block?  Data block is the optimum level of storage. Also known as pages, 
            each data block corresponds to a specific number of bytes. Adjacent 
            data blocks form an extent. Oracle - What

            at 11:00 AM What is Data Block?  
              Data blocks are also called logical blocks, Oracle blocks, or 
              pages. 
              At the finest level of granularity, Oracle stores data in data 
              blocks. 
              A data block corresponds to a specific number of bytes of 
              physical database space on disk.  Also readAn extent is stored some specific information. This information 
            is stored using specific number of adjoining data blocks. A 
            collection of extent is called as a segment stored in the same 
            tablespace............. 
             A data block is the smallest unit of logical storage for a 
            database object. As objects grow they take chunks of additional 
            storage that are composed of contiguous data blocks..............
