IMPLEMENTING TOPOLOGICAL INTEGRITY CONSTRAINTS ON TEMPORAL DATABASES

Tóm tắt

Checking integrity constraints in real-time the database is an important field of investigation. In this paper, we implement topological integrity constraints depending on which user has chosen an integrity constraint on different times on many existing integrity constraints of temporal databases. We suggested using the Hamiltonian paths in directed graphs order to implement a test program on data simulated by a college's real data. The object needs to satisfy integrity constraints in temporal databases as students who have enrolled in the subjects. Moreover, the program also monitors the learning process and advises students to choose courses in the school's training program.
