Discussion: Should delete really delete?

Let's say I am an analytics person and I would like to look at my history.
I would like to see what I have done 1 month/year ago.

If we really destroy the data/task from the database, we can't make the report.

I have 2 suggestion about this:

`IsDeleted`
In the tasks table, there can be a column, called `IsDeleted` --not very suggested

`HISTask`
We can create a new table, called `HISTask` (HistoryTask - it can be renamed) and we can have deleted date and updated date.
When we insert the task, we will insert it on HISTask too.
When we make reports about tasks, we will include HISTask on the query.
