Rough development policy

• Based on layered architecture.
• Since the unit of aggregation is only task, there are no modules or packages that are conscious of aggregation.
  • For example, there is no directory named task.
• Try not to depend on libraries as much as possible at the application or domain layers.
• Task identifiers are serial numbers.
• Executing domain behavior is not allowed in presentation layer.
