使用一个大型数据库或每个客户使用单个数据库 [英] Use one large database or use single databases per customer

问题描述

目前，我正在开发一种用于建筑材料的在线网络应用程序。公司可以登录我们的网站，然后他们可以使用webapp。

Currently I'm working on a on-line webapplication for construction materials. Companies can log in on our website and then they can use the webapp.

从一开始，想法是为每个客户创建一个数据库。但是现在它越来越大（100+），所以我们现在有100个数据库来管理。

From the beginnen the idea was to create a database per customer. But now it's becomming larger and larger (100+) so we have now 100 databases to manage.

我们必须运行约。每年两次更新db maintanance的更新脚本。

We have to run approx. twice a year an update script for db maintanance.

我看到的好处是，当客户想要退出时，我们删除他们的数据库，而不是完成。

The advantage that I see, is that when a customer wants to quit, we delete their database and than it's finished.

当我想添加新客户时，我需要填充数据库。 1.000.000特定客户的唯一记录，因为每个客户有不同的价格/材料。

When I want to add new customer, I have to fill the database with approx. 1.000.000 unique records for that specific customer, because every customer have different prices /materials.

对于备份，我使用MySQL Dump脚本，每天下载的数据库创建一个* .sql文件。

For backups I use a MySQL Dump script, that creates a *.sql file per database that I download every day.

你的看法是什么，你觉得怎么样？
一个大数据库或每个客户一个数据库？

What is your opnion and what do you think? One large db or per customer a database?

我使用MySQL与ASP.NET / C＃...

I'm using MySQL with ASP.NET/C#...

推荐答案

我不想提出建议，因为有太多的变量。

I don't want to make a suggestion because there are far too many variables.

但我想说明的是，我的雇主有1000个部署的数据库 - 我们每个客户使用一个数据库进行复制（2+数据库）。

I do want to note, however, that my employer has 1000s of deployed databases -- we use one database per customer with replication (2+ databases).

所以，这个想法是可行的。我的工作与DB管理无关，但我记得我们在自动化和在线工具方面做了很多。备份和数据库管理由团队处理。

So, the idea is workable. My job isn't related to DB management but I do recall that we do a lot in the way of automation and online tools. Backups and DB management is handled by a team.

最终，您可以使100多个部署工作，但是您将要开始投资开发实用程序和工具来帮助自动化DB的备份和/或管理。

Ultimately, you can make the 100+ deployments work but you are going to want to start investing in the development of utility and tools to help automate the backup and/or management of the DBs.

理想情况下，没有什么（DB管理）应该手工完成。此外，连接字符串应当从给定的web应用部署抽象化。

Ideally, nothing (DB Management) should be done by hand. Furthermore, the connection strings should be abstracted away from a given web app deployment.
