Replace or modernize RPG-AS/400 systems

Many businesses have core systems based on Report Program Generator (RPG), the software on the IBM AS/400 and iSeries computer systems. Although these applications still prove their worth, they have great difficulty meeting today's requirements. These days, they prove to be a drag on organizations when they want to launch web shops or apps quickly.

Discover the Thinkwise development platform, specifically designed for complex core systems. Thinkwise is a leading specialist when it comes to replacing RPG-AS/400 systems with a sustainable low-code solution.


Thinkwise: the driving force behind your digital transformation

It is very difficult to hire RPG programmers, as the programming language is quite old now. To customize entire processes, you need specialized knowledge. You run the risk of quickly becoming dependent on one person. If this person leaves for another job or retires, you are faced with an immediate problem.

Secondly, modifications are difficult to implement with RPG. At the same time, processes are constantly changing! The faster you can adapt, the stronger your competitive edge. As a result, organizations will choose to purchase, implement and manage additional applications. This adds even more complexity to the application landscape. This leads to extra maintenance and increasing costs.

The Thinkwise low-code platform for core systems is flexible and highly future-proof. A core system is online up to 20 times faster than C#-based systems. This enables you to launch a comprehensive ERP system within one year with only 5 FTEs. Through analyzing user actions, the user interfaces and workflows become more and more attuned to the organization, groups and individual colleagues. This means your software automatically evolves with the needs of your business operations.

Applications that grow with your organization

Ultimately, organizations with RPG-AS/400 applications all face the same challenge: how do we make sure our applications can keep up with a rapidly changing world? It's critical to find the right technology before investing massive amounts of time, money and resources. Thinkwise provides the technology to ensure that your application will always remain technologically up to date.

So how does Thinkwise differ from RPG-AS/400s?

  • Always up-to-date

  • Authorization and Permissions

  • Flexible test database

  • Migrate your applications easily

  • Integration

Gone are the days of technologically obsolete software

With Thinkwise, your applications become technology-independent; you only have to maintain the model. The underlying technology, such as User Interfaces, Service Tiers, and databases are periodically updated for you,  without impacting previously built applications. This means that a Thinkwise application will never become legacy in any of these areas and will always remain technologically modern.

Built-in authorization system: no more need for manual programming

The Thinkwise Platform features a built-in authorization system. Many other platforms do not have this part of software development integrated into their systems and has to be programmed manually. Managing and maintaining this properly in the long run is a complex challenge. In addition, it is very easy to create new users, including all associated rights and roles. This is crucial in organizations with many different types of users.

The platform also supports OpenID authentication by default. You can use various OpenID providers, such as Azure AD, Facebook, Gmail, etc. Furthermore, the platform itself can also be used as an OpenID provider, allowing 3rd party applications to use Single Sign-on (SSO) with accounts stored in the Thinkwise Platform.

Rapid & efficient testing

Software development requires a great deal of testing and continuous improvement. The Thinkwise Platform integrates test cases into the model, which means they continue to function properly even after changes to either the data model or the GUI model.

In addition, the Thinkwise development environment lets you automatically generate test cases based on the model.

Modernizing comprehensive systems using the Upcycler

A major added value of the Thinkwise Platform is that it includes an integrated solution for modernizing RPG-AS/400. With the Upcycler you can create a first version of a Thinkwise application by simply importing a RPG-AS/400 application. The result will obviously not be ready for production just yet, but a significant part of the work will automatically have been done for you.

The process to Upcycle a RPG-AS/400 application roughly consists of the following steps:

  1. Extracting model & data
  2. Importing model
  3. Transforming meta model to Thinkwise model
  4. Deploying the application
  5. Importing legacy data into the Thinkwise application

Integration: the key to a data-driven organization

It goes without saying that software needs to be able to communicate with other systems. Our integrated service tier provides secure access to all desired data and functionality through an open API based on the OData protocol.

The Thinkwise Platform offers extensive integration capabilities such as:

  • Database connectivity
  • Web Services
  • Business Intelligence
  • Microsoft Exchange
  • Office and reporting

How does Thinkwise mitigate the risk of Vendor Lock-in?

Thinkwise minimizes lock-in to a minimum by offering open standards. We don't have a proprietary programming language and the entire model you build and the database are directly accessible outside the Thinkwise environment. You can use your own cloud or servers and even deploy the business logic to a location of your choice. In the event that you really want to stop using Thinkwise, everything can be saved or reused, including code comments.

Why wouldn't I face the same challenges with Thinkwise in 10 years?

There are several reasons why this will not happen. The main reason is that the platform itself is built with the platform, just as a 3D printer prints the next, better version of a 3D printer. This means that just like your applications, the platform itself will never become technologically obsolete, so it will not become legacy itself.

The #1 low-code platform for your digital transformation

Thinkwise offers the only low-code platform specialized for realizing large and complex enterprise software. It enables you to deliver solutions at least ten times faster than with traditional software development. Replace and prevent legacy software with applications that automatically stay modern.

Eliminate legacy software, clean up your back-log in no time, and make your organization flexible again with software that seamlessly integrates with your business, but is easily adaptable - even after implementation.
