Describe the key characteristics of the Object Exchange Model (OEM).

What will be an ideal response?

An OEM object can be considered as a quadruple (label, oid, type, value). For example, we
can represent the Staff object &4 that contains a name and salary, together with the name
object &9 that contains the string “Ann Beech” and the salary object &10 that contains the
decimal value 12000 as follows:
```
{Staff, &4, set, {9, 10}}
{name, &9, string, “Ann Beech”}
{salary, &10, decimal, 12000}
```

OEM was designed specifically to handle the incompleteness of data, and the structure and
type irregularity.
