To structure and specify the relationships among attributes in a modelling view. Hierarchies are implemented.
Companies describe hierarchies for classification of information, letting roll-up and drill-down analysis. For instance, a sales company might assign a salesperson to a country and a country is assigned to a region. Then the sales data can be calculated and scrutinized by region, country, or salesperson.
There are two kinds of hierarchies:
<> Level Hierarchies are rigid hierarchies, where you can access the root and the child nodes in the defined order. For instance, organizational structures.
<> Parent/Child Hierarchies are regarded as value hierarchies, i.e, hierarchies obtained from the value of a node. Such as a Bill of Materials (BOM) includes Assembly and Part hierarchies, and an Employee Master record includes Employee and Manager data. The hierarchy can be analyzed on the basis of a selected parent, also, there are scenarios where the child can be a parent
