Tbl design for expiration dates

[LMB]

Hi everyone,

I need to add a table to my existing database which will list the
credentials of each employee and the expiration date of the credentials. My
final report will need to list all the employees, their credentials and show
that they are current with the credentials they have on file. The problem
is that some of the employees have an RRT credential (registered respiratory
therapist) but they were "grandfathered" if they were registered before 2002
which means their credentials do not expire. This is also true for all of
the possible credentials, CRT, CPFT etc... We need to make sure no ones
credentials have expired because salary depends on credentials. I was
thinking a y/n field would be in order but I have not used one before and
can't really visualize how this will work since not all employees will have
all the credentials. My other issue is that not all employees have all
credentials. Any advice would be appreciated.

Would this table set up work?

tblCredentials
CredentialsID(pk)
CredentialType(fk)
EmpID(fk)
CredentialRenewalReq y/n
DateCredentialObtained dtt

tblCredentialType
CredentialTypeID(pk)
CredentialName

Thanks,
Linda

Presumably the credentials are tied to responsibilities, so a staff member
in a particular position must have particular credentials.

One employee could have multiple positions (e.g. 2 days in one role, and 3
in another), and the credentials they need might overlap, but ultimately
they need all the current credentials for each position they hold.

The following tables are probably a minimum:

Position: One record for each staff position.
PositionID

Credential: One record for each credential
CredentialID
Frequency Number How often it needs renewing.
PeriodType Text "yyyy", or "m", or "d"

PositionCredential: One record for each credential you need for a position.
PositionID
CredentialID

Employee: One record for each person.
EmpID

EmployeePosition: One record for each position an employee works.
EmpID
PositionID

EmployeeCredential: One record for each credential an employee has.
EmpID
CredentialID
AcquireDate Date/Time when certified
ExpireDate Date/Time when needs to be renewed.

With that structure, you can determine what credentials an employee should
have (based on the positions they currently work), and what credentials they
currently have (based on the EmployeeCredential table). That lets you
determine gap (anything they don't hold that they should), and what
credentials are expiring soon.

The suggestion to include an ExpireDate in EmployeeCredential is arguable,
but:
a) You can set a date of 1/1/2999 for the employees whose credentials never
expire.

b) If someone decides that, from today a certificate now expires every 6
months instead of every 12 months, you can change the Frequency in the
Credential table, without affecting those who already have a piece of paper
to say they are qualified for 12 months.

c) In the screen where you enter the EmployeeCredential, the database can
calculate the expiry date for you, as:
DateAdd([PeriodType], [Frequency], [AcquireDate])
but the user can override and shorten or lengthen the date for particular
cases.

HTH.

Thanks, Allen,

Credentials do not drive anything but pay. We just need a report that shows
all employees and what their credentials are and if and when their
credential expires. The other things that you suggested are similar to
other tables that are already set up and working well for us. I thought
maybe by using a y/n field I could eventually run a report that would show
the employees who didn't need certain credentials renewed but I have been
drawing it out and can't seem to get how to set it up since there will be
some employees who have some credentials that do not expire and some that
do.

Why not just set an expiry date of say December 31 2999 as the expiry date?
It is rather unlikely that your database will still be in use then.

That was my initial idea but I thought there may be a better way to handle
it, but it may be too complicated for me anyway. Probably involve some
code. I can do this one probably all by myself.
