列名:它应该是单数，只有这样它才表示它将持有一个原子值，并将确认归一化理论。然而，如果有n个相同类型的属性，那么它们应该以1,2，…作为后缀。n，等等。

我的朋友Patrick Karcher，我请求你不要写任何可能冒犯别人的东西，就像你写的那样，“此外，外键必须在不同的表中一致命名。如果有人不这样做，殴打他应该是合法的。”我从来没有犯过这样的错误，我的朋友帕特里克，但我写一般。如果他们一起打算为此揍你呢?：）

我总是听到这样的争论，即表格是否多元化完全是个人品味的问题，没有最佳实践。我不相信这是真的，尤其是作为一个程序员而不是DBA。据我所知，除了“这对我来说很有意义，因为它是对象的集合”之外，没有其他合理的理由将表名改为复数形式，而使用单数表名在代码中有合理的好处。例如:

It avoids bugs and mistakes caused by plural ambiguities. Programmers aren't exactly known for their spelling expertise, and pluralizing some words are confusing. For example, does the plural word end in 'es' or just 's'? Is it persons or people? When you work on a project with large teams, this can become an issue. For example, an instance where a team member uses the incorrect method to pluralize a table he creates. By the time I interact with this table, it is used all over in code I don't have access to or would take too long to fix. The result is I have to remember to spell the table wrong every time I use it. Something very similar to this happened to me. The easier you can make it for every member of the team to consistently and easily use the exact, correct table names without errors or having to look up table names all the time, the better. The singular version is much easier to handle in a team environment. If you use the singular version of a table name AND prefix the primary key with the table name, you now have the advantage of easily determining a table name from a primary key or vice versa via code alone. You can be given a variable with a table name in it, concatenate "Id" to the end, and you now have the primary key of the table via code, without having to do an additional query. Or you can cut off "Id" from the end of a primary key to determine a table name via code. If you use "id" without a table name for the primary key, then you cannot via code determine the table name from the primary key. In addition, most people who pluralize table names and prefix PK columns with the table name use the singular version of the table name in the PK (for example statuses and status_id), making it impossible to do this at all. If you make table names singular, you can have them match the class names they represent. Once again, this can simplify code and allow you to do really neat things, like instantiating a class by having nothing but the table name. It also just makes your code more consistent, which leads to... If you make the table name singular, it makes your naming scheme consistent, organized, and easy to maintain in every location. You know that in every instance in your code, whether it's in a column name, as a class name, or as the table name, it's the same exact name. This allows you to do global searches to see everywhere that data is used. When you pluralize a table name, there will be cases where you will use the singular version of that table name (the class it turns into, in the primary key). It just makes sense to not have some instances where your data is referred to as plural and some instances singular.

总而言之，如果你将表名改为复数，那么你就失去了让你的代码更聪明、更容易处理的所有优势。甚至在某些情况下，您必须使用查找表/数组来将表名转换为本可以避免的对象或本地代码名。虽然一开始可能感觉有点奇怪，但单数表名比复数表名具有显著优势，我相信这是最佳实践。

我建议你看看微软的SQL Server样本数据库: https://github.com/Microsoft/sql-server-samples/releases/tag/adventureworks

AdventureWorks示例使用了非常清晰和一致的命名约定，它使用模式名组织数据库对象。

表的单数名称 列的单数名称 表前缀的架构名称(例如:SchemeName.TableName) 帕斯卡壳(又称上驼峰壳)

Table names should always be singular, because they represent a set of objects. As you say herd to designate a group of sheep, or flock do designate a group of birds. No need for plural. When a table name is composition of two names and naming convention is in plural it becomes hard to know if the plural name should be the first word or second word or both. It’s the logic – Object.instance, not objects.instance. Or TableName.column, not TableNames.column(s). Microsoft SQL is not case sensitive, it’s easier to read table names, if upper case letters are used, to separate table or column names when they are composed of two or more names.
