Crafting an optimal innovative solution requires careful assessment of the system’s current state, aligning with evolving business needs, and balancing security, performance, and budget constraints.
The Database Column Expansion Project was initiated to enhance the brewery system, expanding the Product ID field from 2 bytes to 4 bytes—a change essential for supporting future product introductions.
Identifying every impacted Product_Id column across 128 applications developed in various programming languages was complex, given inconsistent naming conventions across tables.
The initiative demanded rigorous planning and efficient execution to handle the high transaction volume that the brewery system handles while ensuring that the system’s performance wasn’t compromised.
To facilitate this process, a comprehensive impact analysis utility was created using Oracle PL/SQL, leveraging stored procedures and packages, to accurately identify and verify the impacted columns.
The approved design utilized a more streamlined and efficient approach with views and synonyms to ensure the smooth operation of both remediated and non-remediated applications.
The development of source code for each database view object, “Instead of” triggers, and other associated components would require several hours per day, prompting the development of a robust automation framework using Oracle PL/SQL and UNIX Shell scripting.
A comprehensive performance tuning initiative, combining proactive and incremental tuning with continuous monitoring, dramatically optimized data processing speeds.
This project successfully delivered a groundbreaking solution for database column expansion across multiple systems, enabling seamless scalability for future product launches.
Through the automation of database component creation and compilation, significant cost savings and enhanced operational efficiency were achieved.
