在python中创建一个小型数据库的最佳做法是什么？

If I want to create a small database in Python, what would be the best practice to do it?

如果我想在Python中创建一个小型数据库,最好的做法是什么?

For instance, if I want to store output from Cisco's command "sh ip route" in a database,

例如,如果我想在数据库中存储思科命令“sh ip route”的输出,

O       1.1.1.1 [110/2] via 10.0.0.1, 00:00:23, FastEthernet0/0

stores these values:

存储这些值:

1.1.1.1 —> next hop, outgoing interface, source (like O, C, S)

1.1.1.1 - >下一跳,出接口,源(如O,C,S)

Using postgreSQL, mySQL

使用postgreSQL,mySQL

A nested dictionary something like this {'1.1.1.1':{next hop: {outgoing interface: source}}

嵌套字典类似于这样的{'1.1.1.1':{next hop:{outgoing interface:source}}

a dictionary with a list as a value {'1.1.1.1':[next hop, outgoing interface, source]}

列表作为值{'1.1.1.1':[下一跳,传出接口,源]}的字典

Any other option?

还有其他选择吗?

I feel that SQL would be the best solution but if not SQL, what is another option?

我觉得SQL会是最好的解决方案,但如果不是SQL,那么另一种选择是什么?

routing tables look to have a form more similar to documents that relational tables in a RDBMS like Postgres or MySQL.

路由表看起来有一个更类似于像Postgres或MySQL这样的RDBMS中的关系表的文档的表单。

I would prefer to use a document oriented database in this case. Regarding which database to use it depends on your deployment scenario and application architecture.

在这种情况下,我更倾向于使用面向文档的数据库。关于使用哪个数据库取决于您的部署方案和应用程序体系结构。

If your aim is a database server which can be accessed via the network then Mongo is a very good choice. If you are going for a single-node application which will access the data only locally, then you can have a look in TinyDB.

如果您的目标是可以通过网络访问的数据库服务器,那么Mongo是一个非常好的选择。如果您要使用仅在本地访问数据的单节点应用程序,那么您可以查看TinyDB。

With TinyDB your code would look like:

使用TinyDB,您的代码将如下所示:

 from tinydb import TinyDB, Query

 db = TinyDB('/path/to/db.json')
 db.insert({ 'Destination': '1.1.1.1',
             'NextHop': '10.0.0.1',
             'A': '*',
             'P': 'B',
             'Prf': 170',
             ....
            })

And finally look for the individual routes as:

最后寻找各个路线:

  route = Query()
  db.search(route.Destination == '1.1.1.1')
  # [{'Destination': '1.1.1.1','NextHop': '10.0.0.1','A': '*',...}]

or get all of them at once:

或者立刻获得所有这些:

  db.all()

Hope it helps!

希望能帮助到你!
