In a many-to-many connection relationship, there will be issues of duplicate calculations when performing aggregated calculations.

正確答案是：D: A connection relationship can be established and used for aggregated calculations。

專業(yè)分析：

1. **多維分析模型**：從圖中四個(gè)表（Retail, Store, Product, Store Daily Target）來(lái)看，這些表之間存在多對(duì)多的關(guān)系，尤其是在Retail表和Store Daily Target表之間。因此，這種模型通常屬于星型或雪花型模型，用于多維數(shù)據(jù)分析。

2. **表之間的連接關(guān)系**：
- **A: A connection relationship can be established, and the correspondence is many-to-many**：這是正確的。從圖中可以看出，Retail表和Store Daily Target表之間可以建立多對(duì)多的連接關(guān)系。
- **B: There is more than one common field that can be used**：這是正確的，圖中顯示有多個(gè)共同字段可以用于連接。
- **C: After establishing a connection between the two tables, the aggregated calculation results have no practical reference significance**：這是正確的，因?yàn)槎鄬?duì)多關(guān)系可能導(dǎo)致聚合計(jì)算結(jié)果失去實(shí)際意義。
- **D: A connection relationship can be established and used for aggregated calculations**：這是不正確的。由于多對(duì)多的關(guān)系，直接進(jìn)行聚合計(jì)算可能會(huì)導(dǎo)致結(jié)果失真或無(wú)意義。

因此，選項(xiàng)D是不正確的，因?yàn)楸M管可以建立連接關(guān)系，但由于多對(duì)多的關(guān)系，直接進(jìn)行聚合計(jì)算是不合適的。
