Every modernization journey needs a solid foundation, and for IBM i, that foundation is your code and data.
Before transforming interfaces, APIs, or infrastructure, modernizing your database structures and core business logic delivers the biggest early wins in performance, flexibility, and long-term maintainability.
The DDS Bottleneck
For decades, Data Description Specifications (DDS) have been the backbone of IBM i physical and logical files. While DDS has served well for decades, now it’s showing its age.
DDS structures limit how you can access, query, and integrate your data with modern tools. As organizations increasingly rely on analytics, APIs, and real-time integration, those limitations become bottlenecks.
By converting to SQL/DDL (Data Definition Language), organizations unlock:
- Faster data access and reporting using modern SQL tools
- Improved interoperability with web, analytics, and cloud platforms
- Enhanced scalability and indexing options
- Better database integrity and referential control
In short, SQL/DDL transforms your database from a static repository into a dynamic asset for business intelligence and modernization.
Modern RPG for a Modern Workforce
IBM i Modernization isn’t just about the data layer; it’s also about the code that drives your business.
Many organizations still rely on RPG III or fixed-format RPG, which can be difficult for new developers to maintain. By converting to free-format RPG, you gain:
- Cleaner, more readable code that aligns with modern programming standards
- Easier onboarding for new or non-traditional IBM i developers
- Reduced technical debt through modular, service-oriented design
- Support for modern tools and development environments
A modernized codebase doesn’t just make your applications faster; it makes your team more capable and your organization more sustainable.
Tools That Make It Happen
IBM i modernization doesn’t require starting from scratch. It relies on proven tools that help organizations modernize existing applications safely and incrementally.
Key tools and approaches include:
-
Database modernization tooling that converts legacy definitions into modern SQL structures, improving performance and accessibility.
-
Modern SQL techniques are embedded directly into existing applications to support faster queries and greater flexibility.
-
AI-assisted development tools that help refactor and document legacy code, reducing risk and accelerating progress.
-
AI-powered development environments, including emerging tools like IBM’s Project Bob, support application modernization and improve developer productivity over time.
Together, these tools accelerate modernization while minimizing risk and preserving the reliability IBM i is known for.
