I cannot remember working from home this year (Jan-Apr) on a database. I did work from home in February for a couple of days but that did not involve database work.
I would have sent the database via my work email address which I could log onto from home. However I honestly cannot remember the last time I worked on the database from home. It's only a guess but I would think around 18-20 months ago (from my leaving date of April this year). And yes, the MD always knew what I would be working on from home.
