Perkembangan Model Data Temporal serta Implementasinya pada Database Management Systems

This essay examines how temporal data models are created and they integrated into database management systems. The well-known Relational Data Model’s extension, the Temporal Model, is discussed. application of this model in systems also researched. Historical Model adds timestamps to attributes, tuples. These two approaches make up model. It has become apparent via implementation that not all ideas applicable IBM DB2 explicitly idea time stamps, but PERIOD type.
