To bind the weekly patterns together, a group pattern is used.

This entity would record the different types of working patterns. This weekly work pattern would not include the public holiday or company given holiday. These patterns cover a period of 1 week from Monday to Sunday. Any day of the week can be set as full-day, half-day, quarter-day, off-day or as a holiday.

The group pattern will then be recycled for the whole Working Calendar.

Shows the week number of the group work pattern. It also holds the primary key for the GroupWorkPattern table.
