Idea Summary
Enhance Oracle APEX by introducing native Tree-Structured Reporting and Searchable LOVs for Classic Reports, Interactive Reports, Interactive Grids, and Faceted Search. This would enable hierarchical data representation with multiple fields per node, built-in subqueries for aggregations (counts, sums), and a fully searchable Tree-based Popup LOV. Additionally, a Directory-Like Component would provide an intuitive way to navigate hierarchical datasets.
Key Features:
Tree-Structured Reports & Grids
- Enable native hierarchical data visualization.
- Allow multiple fields per node with proper alignment.
- Support built-in subqueries to compute related aggregations (e.g., counts, sums).
Searchable Tree in Popup LOVs
- Introduce a tree-based Popup LOV, allowing users to search within the hierarchy.
Hierarchical Aggregations
- Compute counts at the leaf level and aggregate values up to parent nodes.
New Directory-Like Component
- A file-explorer-style UI for hierarchical navigation.
- Expand/collapse nodes for easier data exploration.
- Drag-and-drop support for reordering where applicable.
Use Cases
1. Quality Assurance Management
QA teams track application components in a hierarchical tree, with each node linked to test cases, defects, and executions. Seeing real-time aggregated counts at every level improves progress tracking, while a searchable tree-based Popup LOV helps locate components quickly.
2. Accounting & Financial Reporting
European accounting structures require multi-level hierarchies where credits and debits roll up dynamically from transactions to parent accounts. A tree-based report simplifies financial analysis.
3. Project & Resource Management
Organizations structure data as Departments → Teams → Projects → Tasks or Countries → Regions → Locations. APEX users would benefit from real-time aggregation and drill-down navigation.
4. Directory-Like Component for Hierarchical Navigation
A new directory-style UI would streamline navigating structured data, such as:
- HR Org Charts: Display departments and employees.
- Product Catalogs: Browse categories and items.
- Knowledge Bases: Organize articles in a structured tree.
Preferred Solution (Optional)
A Tree View Rendering Engine could integrate with existing reporting components, leveraging Oracle’s hierarchical SQL (CONNECT BY
, WITH RECURSIVE
).
For Popup LOVs, support:
- Lazy loading for large datasets.
- Full search & filtering.
The Directory Component would function as a hierarchical UI control, with:
- Drag-and-drop reordering.
- Expandable/collapsible nodes.
- Dynamic access control.
By implementing these features, Oracle APEX would revolutionize hierarchical data management, making it a must-have for developers and business users alike.
