If some of those fields are required if Critical=True, you would be
better off with a second table with a 1:1 relation with the first one.
If the fields are not required, or if there are sensible defaults in
case Critical=False, I would KISS and keep everything in one table.

I need guidance on my database design:
I have a table that lists out several tasks in field 1, and includes about 7
other fields of information on the task.
Some of these tasks are "Critical". If a task is critical, I need about 10
more fields with data on the task.
Am I better off storing this info in 2 tables, or one? It is possible for a
task that is currently not critical, to later become critical.
I need a way to be able to easily keep track of and update this data. Any
ideas?
