问题描述
每隔一段时间我就会看到一些广告，其中包含体验与
大型数据库...多次演出... blah-de-blah我不得不笑。
大型或小型数据库之间有什么区别？一个表是一个
表，一个记录是一个记录，一个字段是一个字段。你所做的就是操纵表中的数据。
我不认为它会有很大的不同
使用一张包含10条记录或十亿条记录的表格...它们是
不再比行和列。
这就像说必须能够处理大量资金
一个应用程序是否适用于10s ，1000美元，100万美元，或者100亿美元的美元，它只不过是一个价值......相同的概念与
一起使用......所有这些...只需要准确。
或者我错了？尺寸真的很重要吗？
Every now and then I see ads that state something like "Experience with
Large Databases ...multi-gig...blah-de-blah" And I have to laugh.
What''s the difference between a large or small database? A table is a
table, a record is a record, a field is a field. All you are doing is
manipulating data in tables. I wouldn''t think it''d make much difference
in working with a table with 10 records or a billion records...they''re
nothing more than rows and columns.
That''s like saying "Must be able to work with large amounts of money"
Whether an app works with 10s, 1000s, 1000000s, or 1000000000s of
dollars, it''s nothing more than a value...the same concepts work with
all of them...it simply needs to be accurate.
Or am I wrong? Does size really matter?
推荐答案
当然可以。人们可以通过使用小型数据库来解决大量无效的问题。如果你雇用一个专门从事小型项目工作的人，他们就有更大的可能性，他们还没有学会所有的最佳实践。对于数据库（特别是
，将网络流量保持在最低水平）。有大量数据库经验丰富的人将会学习如何使数据库应用程序尽可能高效地生成。

It certainly does. One can get away with doing LOTS of things wrong in
terms of inefficiencies with small databases. If you hire someone who has
worked exclusively on smaller projects there''s a higher chance that they
have not yet learned all of the "best practices" for databases (particularly
keeping network traffic to a minimum). Someone who has a lot of experience
with large databases will already have learned how to make db apps as
efficient as possible.

从理论上讲，它们之间存在差异实践和理论归结为实际考虑因素，理论家们认为它适合他们的理论是不切实际的。
In实践中，理论使用理论实践来解释实际问题，而没有注意到理论上的b $ b方法实际上扭曲了理论而不是应用到了
练习。
从理论上讲，实际的事实是，理论实际上，b
预测理论上会发生什么，
但是作为一种直接影响
实践的理论是不切实际的，除非理论上说这种做法足够接近理论来制造一个差异为
所有实际用途理论上都为零。
在实践中，这种情况不会经常发生。
换句话说，是的，它会产生影响。
小型数据库不需要同等程度的护理，
因为效率低下的影响很可能是b
。将这些相同的问题放入一个大型数据库中，并且你可以最终被用户诅咒。
From http://www.kettering.edu/~jhuggins/humor/theory.html:
"In theory the difference between practice and theory is due
to practical considerations that theorists find it
impractical to fit into their theories.
"In practice, theory uses the practice of theorising about
practical matters, while not noticing that the theoretical
method practically distorts the theory beyond application to
practice.
"Theoretically then the practical facts are that the theory
is in practice good for predicting what happens in theory,
but impractical as a theory with direct implications for
practice, except where theory states that the practice is
sufficiently close to the theory to make any difference for
all practical purposes theoreticaly zero.
"In practice this does not happen very often."
In other words, "Yes, it makes a difference."
Small databases don''t require the same degree of care,
because the effects of inefficiencies are likely to be
minor. Put those same problems into a large database, and
you can wind up being cursed by your users.

我倾向于不同意你和Rick。有些人对他们所做的事情有好处，而对那些并不那么好的人有好处。我确定你已经在一个项目上工作了b $ b你想知道以前的程序员是否是脑子
死了。
如果一个人胜任，我认为这没关系。所有你用b $ b做数据库操作数据。
我怀疑我找到了工作，有人会说沙拉，我们需要你在ABC数据库工作
。它有十亿条记录，而且是两百亿美元的大小。我颤抖，震颤，口吃......但是先生......我只是在一个不到一场演出而且不到一百万的数据库上工作了一个b $ b
记录！然后冲出房间，抽泣和哭泣，因为我把它给了洗手间，在那里我用羞辱和恐惧来呕吐我的肚子。
我会改为说酷，我的小隔间在哪里？我想查看
表及其结构。
I tend to disagree with both you and Rick. There are people that are
good at what they do, and those that aren''t so good. I''m sure you''ve
worked on a project and you wonder if the previous programmer was brain
dead.
If one is competent, I should think it doesn''t matter. All you are
doing with a database is manipulating data.
I doubt I''d get a job and someone would say "Salad, we need you to work
on ABC database. It''s got a billion records and is 250 gigabytes in
size." and I quiver and quake and stutter..."But sir...I''ve only worked
on a database that was less than a gig and had less than a million
records!" and then rush out of the room, sobbing and crying as I make it
to the restroom where I retch my stomache dry in humiliation and fear.
I''d instead say "Cool, where''s my cubicle? I want to look over the
tables and their structures."
