Suppose you run a supermarket and have 100 kilograms of rice to sell. But someone comes to buy and only buys 60 kilograms of rice. This is called a partial transaction. If not long after, someone comes to buy 40 kilograms of rice. Rice, your rice is sold out at this time, which is called all transactions. If the first one who comes to buy directly buys 100 kilograms of rice, it is all transactions directly.
