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.
