How are tables stored on Disk?
We realise that every record of a table can have different amounts of data. This is due to in some records; some attribute values may be "zero". Or, some attributes might be of type varchar (), and thus each record may have a dissimilar length string as the value of this attribute. Thus, the record is stored with each subsequent attribute splitted by the next by a special ASCII character known as a field separator. Of course, in every block, we may place several records. Every record is separated from the next, again by another special ASCII character known as the record separator.
Define blocks? The database system resides eternally on non-volatile storage, and is into fixed-length storage units known as blocks.
