Aside from is a/has a considerations, one must also consider the "depth" of inheritance your object has to go through. Anything beyond five or six levels of inheritance deep might cause unexpected casting and boxing/unboxing problems, and in those cases it might be wise to compose your object instead. |

AFAIK, JSON and YAML are exactly equivalent in data structure terms. YAML just has less brackets and quotes and stuff. So I don't see how you are rejecting one and keeping the other.

How about [unison](http://www.cis.upenn.edu/~bcpierce/unison/)?

You can either log to a table, by simply inserting a new row, or you can implement a CLR stored procedure to write to a file.
Be careful with writing to a table, because if the action happens in a transaction and the transaction gets rolled back, your log entry will disappear. |
Logging from inside a SQL sproc would be better done to the database itself. T-SQL can write to files but it's not really designed for it.
|
I think writing to a log table would be my preference.
Alternatively, as you are using 2005, you could write a simple SQLCLR procedure to wrap around the EventLog.
Or you could use **xp_logevent** if you wanted to write to SQL log |
There's the [PRINT][1] command, but I prefer logging into a table so you can query it.
