OBIEE 11g is an enterprise business intelligence (BI) platform that provides organizations with powerful analytics and reporting capabilities. Creating a parent-child hierarchy is a key feature of OBIEE, allowing users to view data in a more organized and meaningful way. This article provides step-by-step instructions on how to create a parent-child hierarchy in OBIEE 11g, using real-life examples to illustrate the concepts.
The first step is to identify the entities you want to include in the hierarchy. For example, if you are analyzing sales data for a retail store, you might have entities such as products, categories, and departments. Once you have identified your entities, create a relationship between them using OBIEE’s "Parent-Child" option in its data model builder.
After creating the hierarchy, use it to view data in a more organized way. Drill down from the product level to the category level or department level using the hierarchy. Use OBIEE’s built-in aggregation functions to calculate summary statistics such as total sales, average sales, and maximum sales. This will help you quickly identify trends and patterns in your data.
The benefit of a parent-child hierarchy is that it allows you to view data from multiple perspectives. You can view sales data by product, category, department, or any combination of these. This makes it easier to identify which products are performing well and which ones are not.
In conclusion, creating a parent-child hierarchy in OBIEE 11g is a powerful tool for analyzing and visualizing data. By identifying your entities, creating relationships between them, and using aggregation functions to calculate summary statistics, you can quickly identify trends and patterns in your data. With the right approach, you can use OBIEE to make informed business decisions that drive growth and profitability.
