Scaling up to the ecosystem levelBanks”. This was a mathematical description of what we now call Relational databases and operations to manipulate them. This is called relational algebra where data could be organised into relations (tables) consisting of tuples (records), each with consistent attributes. The tables could be linked 作者: VERT 時間: 2025-3-22 17:55
Dennis D. Baldocchi,Kell Wilson seem like a bad idea to experienced relational database practitioners, but these tools do certainly have their place in today’s data rich society.
