Why modernize?


Scarcity of domain expertise

Developers who understand ADSO, ADSA, IDMS, and mainframe technology are reaching retirement age and no one is trained to replace them, resulting in a steadily diminishing talent pool. As this shortage grows, the costs and risk of relying on these technologies will continue to rise.

Limited flexibility

Companies are rapidly moving to modern environments and practices such as DevOps and the Cloud. However ADSO, ADSA, IDMS and the underlying systems that support them were not designed for modern IT, resulting in difficult integrations and limited flexibility.


Exorbitant costs

Mainframes running ADSO, ADSA, and IDMS cost as much as 4,500 per cent more to operate than equivalent Cloud counterparts. This figure is compounded by the rising licensing and maintenance fees for these specialized technologies. 

Automated ADSO Refactoring


Dealing with pre-relational network databases has long been the domain of specialist DBAs. Unfortunately, this talent pool is shrinking rapidly as IDMS specialists reach retirement age, creating scarcity, driving up maintenance costs, and compounding risk. As companies seek to migrate away from IDMS, they must also account for ancillary components such as ADSO, an abstraction tool used to develop modular applications using IDMS databases, when making the shift.

Our Automated ADSO Refactoring solution provides a turnkey modernization of your ADSO dialogs to object-oriented Java or C#, and your associated IDMS databases to relational models deployed to the Cloud or on premises. This service also includes IDMS-based application components such as process modules, maps, ADSA structures, edit and code tables, automatic editing, IDD messages, scratch and queue processing, and IDMS-DC language subroutines.

Our solution preserves the benefits of legacy systems while empowering organizations to leverage the advantages of newer platforms, especially the Cloud. This unlocks a whole new world of automation and scalability from automated testing to quality assurance, and the ability to leverage containerized deployments and orchestration with Docker and Kubernetes.

Refactoring ADSO and its related components to object-oriented Java or C# presents many challenges. As such, our Automated ADSO Refactoring solution was designed with the following requirements in mind:

  • Refactored applications must remain functionally equivalent to their original counterparts
  • Refactored applications must be easily maintainable, attain SonarQube A ratings, and follow object-oriented concepts and paradigms
  • Refactored applications should perform as well as, or better than, the original applications
  • Refactored applications should be Cloud-ready and delivered using a standard DevOps toolchain and best practices
