Default Vehicle Waiver Database

Is an Org the same as a Unit?

UserCode1, etc. should not be in the table. I assume those are the waived
items, but whatever they are, they should be stored in a related table.

I assume the word is supposed to be "officers" in "Each unit can have offices
assigned." There should be an Officers table, as each entity should be
stored in its own table. If an officer may be assigned to more than one unit,
there needs to be a junction table between tblUnit and tblOfficer (the unit
and officer tables).

tblUnit
UnitID
UnitName
etc.

tblOfficer
OfficerID
FirstName
etc.

tblUnitOfficer
UnitID
OfficerID
Other fields for data about a specific officer assigned to a specific unit

tblVehicle
VehicleID (PK)
UnitID
RegNumber

tblWaivedItem
WaivedID
VehicleID
ItemDescription

Each Unit (or Org?) may have several vehicles, each of which may have several
waived items. Each Unit may have several Officers, but is there a direct
connection between Officers and Vehicles?

These are some very general thoughts. The meaning of master code, sub-code,
and some other fields is not always clear.

I need help in creating a solid table structure for tracking vehicle waivers.
I posted this before, but I cannot find the related post. I will try to give
as much detail as possible.

Scenario: A vehicle maintenance shop needs to keep track of all items
on a vehicle that will not be repaired due to cost effectiveness, non safety
related or cosmetic items (minor dents and scratches, cracks in the dash,
non-essential light inop and so on). These items that will not be repaired
are waivered on a form that is kept in the vehicle. It is also the
maintenance shops responsibility to send a report quarterly to each vehicle
control officer of all waivered items for their vehicles.

Details: Vehicles are assigned to a unit and each unit is designated by
a master code. Each unit can have offices assigned and they are designated by
a sub-code. In addition, the master code can also be used as a sub-code (i.e.
Civil Engineering is master and shop within, like, A/C, water, roads and
grounds are subs).

Each unit has a vehicle control officer assigned to it who will receive
the quarterly waiver report for their unit.

Each vehicle is assigned a unique registration number and waivered
items are strictly unique to each vehicle.

Here is what I have so far:

tblOrgs:
MasterID (PK)
MasterOrgCode
OrgName
Address
UserCode1
UserCode2
UserCode3
UserCode4
UserCode6
UserCode7
UserCode8

tblUsers:
UserID (PK)
UserCode
MasterID (FK) from tblOrgs
UserName
VCOID (FK) from tblVCO

tblVCO:
VCOID (PK)
MasterID (FK) from tblOrgs
VCOName
Phone
Email

tblVehicle:
VehicleID (PK)
RegNumber
MGMTCode
UserID (FK) from tblUsers

tblWaiver:
WaiverID (PK)
VehID (FK) from tblVehicle
WaiverDate
ItemWaived
Initials (FK) from tblInitials

tblInitials:
InitialID (PK)
NameLast
NameFirst
ManNO
Initials

I hope I gave enough info and thanks for taking the time to dredge
through this.
