Basic Tools and Technical Challenges,So far we have covered the relational data model in detail including an extension to incorporate time into the model. In this final chapter we will briefly survey various extensions of the relational model which have been under development in recent years, and we will briefly overview some new directions that are being researched.作者: 小蟲 時(shí)間: 2025-3-23 12:43 作者: Arb853 時(shí)間: 2025-3-23 15:30 作者: Fibrinogen 時(shí)間: 2025-3-23 20:54
