A parent-child hierarchy is a hierarchy of members that all have the same type. This contrasts?with level-based hierarchies,where members of the same type occur only at a single level of the?hierarchy. The most common real-life occurrence of a parent-child hierarchy is an organizational?reporting hierarchy chart,where the following all apply:

父子条理的维，其全部成员具有沟通的范例。基于级此外条理的维纷歧样，其范例同等的成员仅处于条理中的统一级别。父子条理的为最常见的现实行使景象是，开拓具有组织讲述条理的图表。详细应用如下：

? Each individual in the organization is an employee.
? Each employee,apart from the top-level managers,reports to a single manager.
? The reporting hierarchy has many levels.

? 组织中的每个个别都是一位雇员。
? 除了顶层打点者，每位雇员都向单个打点者讲述。
? 讲述条理具有许多级别。

In relational tables,the relationships between different members in a parent-child hierarchy are?implicitly defined by the identifier key values in the associated base table. However,for each?Oracle BI Server parent-child hierarchy defined on a relational table,you must also explicitly?define the inter-member relationships in a separate parent-child relationship table.

在副黄?中，父子条理的维的差异成员的相关由关联基表中的标识符的值隐含地界说。可是，对付Oracle BI Server中每个父子条理的维界说在副黄?中，你必需同时明晰地界说内部成员的相关在各自的父子副黄?中。

To create a logical dimension with a parent-child hierarchy,perform the following steps: ? Open the Repository in Offline Mode ? Import Metadata and Define Physical Layer Objects ? Create Logical Table and Logical Columns ? Create a Logical Join ? Create a Parent-Child Logical Dimension ? Define Parent-Child Settings ? Create Presentation Layer Objects ? Test Your Work
