Definition

Datakey is a set of characters formed by different keys combined together. Following these keys will help us to get to the object we want in a hierarchical structure. Datakey can also be used as a unique key for each object to be distinguished in the structure.

Example

In a form, we have the following lines:
Line01: Bill on Dec. 1998 US$ (in thousands)
Line02: Development
Line03: Salaries 1000
Line04: Facilities Cost 200
Line05: General Overhead 800
Line06: Total Development Expenses 2000

A datakey can be set to distinguish each line. Assume that we use 6 characters for each level of hierarchy. Line 3 will have a datakey of 'Line01Line02Line03', while line 6 will have a datakey of 'Line01Line06'.

Note

You can implement the datakey in any way you want. However, you also have responsibility as to make sure that it works the way you want.
