我认为,我知道,从哪里开始这样做,但令人痛心的是,我很早就需要一些援助。 首先,我与我的产品数据相比,需要将四种产品数据清单进行比较。
例如,每个产品清单都有以下数据:
Product Category
Product Name
Inventory
Product Price
Each of the lists have at least a thousand records.
What I need is a fifth list that tells me which of the competitors products I don t have on my list.
最后但并非最不重要的是,如果这种骗局是,库存包含重复记录。
我甚至难以在我花时间处理这个问题。
What I want though is a list of products that are shared by all of the competitors that I do NOT have on my product list.
