Default Table design question

Hi All,

I just wanted to see if the design of some fields in the table are standard
practice.

The database admin set up a Code_Desc table with fields Code_Type_ID,
Code_Value and Code_Desc

Code_Desc
Code_Type_ID, Code_Value, Code_Desc
1 1 Emp Status - Active
1 2 Emp Status - Inactive
2 1 Emp Type - Associate
2 2 Emp Type - Manager
2 3 Emp Type - Auditor
3 1 Error Type - Major
3 2 Error Type - Minor
4 1 Shift - 1st
4 2 Shift - 2nd
etc...

However in tables that use these values she is wanting the Code_Type_ID and
Code_Value combined.

Example:
Audit_History (table)
Shift, Error_ID, Emp_Type (fields)
41 32 21 (combined)

Is this standard? Is this the best approach? To me it adds coding by having
to combine everything, but it also makes it hard for others to run queries on
the Db that have limited query skills. Do you see other pitfalls besides the
one I see?

What is the best way to combine it as well, concatenation?
