1. Primary Schema Relationships

下圖說明了數(shù)據(jù)庫中各集合的主要的schemas: 區(qū)塊, Transaction, Message, and 賬戶. 為提高讀寫性能，降低總體的存儲需要，我們選擇了不要denormalize并且把這些不同的entities nest起來展示他們的關(guān)系。這里同時展示了各個集合的主鍵及其外鍵。

約定

• 主鍵和外鍵的字段名應(yīng)以_id結(jié)尾, 除非是一個keys的列表，如果是列表情況下字段名應(yīng)當(dāng)是列表中包含的對象的schema類型的復(fù)數(shù)形式。

2. 區(qū)塊
