Abstract: An improved bi-temporal relationship model and the related operations such as insert, update and other was presented. This model can clearly differentiate between time-related attributes and normal ones. Then, it can make the analyzing work on temporal data more beneficial. Also, it can accelerate speed when inserting a new record into the database or updating some existed data. In addition, it uses an attribute called “hostNo”, similar to the object number to reduce the frequency of link operation and increase the efficiency.

Key words: time-related attributes , relationship model, bi-temporal database
