Oracle Hyperion Reporting Basic Tutorial

-
Interactive Reporting is an extremely robust and powerful business intelligence tool providing ad-hoc querying, data analysis, dashboards, and other reporting capabilities.

Oracle Hyperion Financial Management

Business analysts access the software through the EPM Workspace, a central location for viewing and managing content across all of the Hyperion products. The product is extremely flexible and provides analysts with the ability to quickly analyze data and produce deliverables.
The software provides a consistent platform for managing content, where documents can be customized, saved, and shared across an organization.

What is BQY

When working with Interactive Reporting, it is hard to escape the term BQY. BQY or BrioQuery, is the extension given to all Interactive Reporting document files.

Developers create BQY files using the Workspace, Interactive Reporting Web Client, or Interactive Reporting Studio—a developer tool used to create and manage BQY documents outside of the EPM Workspace.
 A report is stored as a BQY file. This file contains the formatting and structure for the report.

What is EPM workspace

The EPM Workspace is similar to a portal, where all Oracle Hyperion applications, reports, and other files can be accessed and integrated using a shared security model. 
The Workspace is accessible through the web browser and contains a filesystem and other gadgets including personal pages and content subscription.

Interactive Reporting is one of the many products that integrate with the Workspace, providing users a central location to save, share, and publish content.

EPM Workspace is the Web user interface that is used to access all Oracle and non-Oracle content.

Web client interface topics

Understanding the Web Client interface is crucial to being proficient in the product.

The different sections of the software contain a variety of different options, but the location of where to find and utilize these options is the same across the tool.

Knowledge of the interface and how to leverage the features of each section is key to unlock the full potential of the product.

The sections of an Interactive Reporting document are the different objects in the software used to aid in querying, analyzing, or displaying information.

There are seven types of unique sections. The specifics of each section will be addressed in the following chapters:
  • The Query section is the main section used to set up and execute a query from a relational or multi-dimensional database.Each Query section is accompanied by a Results section where the data returned from the Query is displayed and can be manipulated.
  • The Table section is similar to the Results section and is used to manipulate and split a dataset into different subsets for analysis.
  • The Pivot section is specific to a Results or Table section, and is used to graphically display data in pivot table format—similar to Microsoft Excel Pivots.
  • The Chart section is also specific to a Results or Table section and is used to display data in a chart.
  • The Report section provides the ability to present pivots, charts, and tables of data in a well formatted document.
  • Dashboards are used to create custom interfaces or interactive displays of key metrics.

SQL Query: 3 Methods for Calculating Cumulative SUM

Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...

 Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ...
