Objective: The Leaves Management and Payroll system requires the official weekend hodiday scheme stored

  • 0

Objective:
The Leaves Management and Payroll system requires the official weekend hodiday scheme stored in the database to be referred to while generating the monthly salary for each employee in the organisation. Generating flexible Database Schema for storing the weekend scheme is the objective.

Problem:
The database schema should be flexible enough to allow the changes in the definition of a weekend. The weekend in our scenario may be defined as:

1. Sunday
2. Sunday + 1st or 2nd or 3rd or 4th Saturday
3. Sunday + (1st and 2nd) or (1st and 3rd) or (1st and 4th) or (2nd and 3rd) or (2nd and 4th) or
(3rd and 4th) Saturday
4. Sunday + all Saturdays

    maybe store the scheme like that
    11111 – means Sunday and all Sats
    10000 – means only Sunday
    11010 – means Sunday and 1st and 3rd Sats

    so first number is Sunday, second – 1st Saturday, etc

    You could the use Bitwise OR to check for some values like

    checking for 1st saturday

    SELECT * FROM table_name WHERE holiday_scheme | 01000 > 0

    Hope that helps.
