Question

Could someone help me with a rough database schema for a timesheet application where the i would be able to

Answer 1

Here is a rough sketch that will give you a good start:

Project
-------
ProjectId  PK
ProjectName varchar(200)

Employee
---------
EmployeeId  PK
EmployeeName (or first name/last name etc..)
// .. other employee attributes


ProjectTimesheet
----------------
ProjectTimesheetId PK
ProjectId          FK -> Project.ProjectId
EmployeeId         FK -> Employee.EmployeeId
StartTime          DATETIME
EndTime            DATETIME
Approved           bit

EDIT: As an alternative to the approved flag in each ProjectTimesheet row, you could instead separate out the approved status to a separate table. For example, to allow approval for an employee's timesheet over a given period, a manager would add an approval entry to the Approval table:

Approval
--------
ApprovalID    PK
EmployeeId    FK -> Employee.EmployeeId
StartTime     DATETIME
EndTime       DATETIME
ApprovedBy    FK -> Employee.EmployeeId (e.g. the manager)
ApprovedDate  timestamp  // date the approval was registered
