对于一个事务，例如销售订单的创建，可能有十五个表，以及将要在每个表中进行比较的十到十五个之间的字段。
For a transaction such as the creation of a sales order, there may be fifteen tables and between ten and fifteen fields that are to be compared in each table.
例如，假设有两个分别包含产品信息和销售信息的表，您可以使用联接操作来匹配同一销售订单的销售信息和产品。
For example, given two tables that contain product information and sales information, you could use a join operation to match sales information and products for the same sales order.
