只是想知道是否存在用于保存信息的日志/审核表，例如哪些用户已创建/更改/删除了键或索引等？

Answer 1

The default trace captures DDL changes. Below is an example to glean some of this information.

--Object:Created and Object:Altered events from default trace
SELECT 
     te.name AS EventName
    ,tt.StartTime as st
    ,tt.DatabaseName
    ,tt.ObjectName
FROM sys.traces AS t
CROSS APPLY [fn_trace_gettable](t.path, DEFAULT) AS tt
JOIN sys.trace_events AS te ON
    te.trace_event_id = tt.EventClass
WHERE 
    tt.EventClass in (46,164)
    AND tt.EventSubClass = 0
ORDER BY st DESC;
