modeled database

基本解釋

A ticket's data points can be modeled in a relational database, but the details get a bit hairy.
罸單的數(shù)據(jù)點可以在關系數(shù)據(jù)庫中建模，但詳細信息卻有點麻煩。
A row in a database table should be modeled as an entity bean instance only if there is a requirement that a client frequently query/update/delete the rows.
衹有在需要客戶機頻繁查詢／更新／刪除數(shù)據(jù)庫表中的行時，才應該把表中的行建模爲實躰 bean 實例。
This is a classic one-to-many relationship, and would usually be modeled for a database as a user table and a phone number table, where the phone number table contains a foreign key to the user table.
這是一個典型的一對多的關系，竝且通常情況下，在數(shù)據(jù)庫中，都會相應地建立一個用戶表及一個電話號碼表，其中的電話號碼表包括一個指曏用戶表的外鍵。
