Pagination and Result Windowing Efficiency in APEX Classic vs Interactive Grids

Abstract

This study examines the efficiency of pagination and result windowing in Oracle APEX Classic
Reports versus Interactive Grids, focusing on performance, user interaction behavior, and scalability.
Through controlled comparisons across increasing dataset sizes and concurrency loads, the findings
show that Classic Reports maintain predictable, low-overhead performance due to server-driven
pagination, while Interactive Grids offer richer interactivity at the cost of increased memory usage and
greater sensitivity to dataset volume and session duration. Results indicate that Classic Reports are
best suited for large, frequently paginated datasets, whereas Interactive Grids are most effective in
scenarios requiring dynamic manipulation and inline editing. The study concludes that selecting the
appropriate grid type requires understanding the workload profile and aligning grid behavior with
application requirements.
