Legacy applications

Do You Notice

High maintenance cost
A legacy application is like an antique car – it may continue to operate, but every additional year of usage makes it more fragile and expensive.

Data loss
Almost all legacy applications suffer from a high risk of data loss usually willing or unwillingly when an employee leaves an organization.

User privacy has never been more important. Data should never reside on employee computers and should only ever be accessible by the designated processor.

Legacy systems typically require the end user to perform numerous tedious tasks which usually involve a lot of copy/paste, introducing errors and taking up valuable time.

Legacy systems are not suited to a corporate that is growing through mergers and acquisitions. These systems are unable to easily connect and talk to other systems.

Today there are 2 ways of approaching your actual data rendering set-up. On one side stand alone applications that fill in a specific role within your organization and use a specific pre-defined data pool (for example managing order processes for a specific department such as engineering) and on the other side a central application or data framework that will group together different application and share your data between them to optimize cost and workload.

And this is where Rhea comes in. We work on both possibilities without excluding one or the other in our technical strategy. We do this by revising existing applications and re-writing them to ensure full usage of your data as well as grouping together these applications and through our open approach optimize the actual communication between them.

Intelligent Application Development

At Rhea we use a modular and revolutionized way of looking at business applications and instead of making stand alone and costly applications we re-focus our self to make them: by the low-code principle, Fast, Secure, intelligent and Open.

This will not only ensure they are future proof, but also less costly and easier to use for all levels within your organization.

These applications have the added value that they are developed with a modular approach in mind. What means they can be stacked together as well as work side by side, depending on the businesses needs as we will discuss in the chapter about IDI..

Intelligent Data Infrastructure

Rhea goes one step further and in collaboration with its clients we investigate developing an overhead business application to manage your different data lakes and existing open protocol-based applications. this will ensure that the workload of your employees and administrators will be diminished greatly down the line.

Avoiding a copy paste environment implies that more time is freed up for working on your core business and data is automatically populated over your different systems, this opens the door to an automated system in the future.

Our IDI framework will essentially work as another application connecting your business application together. This means that we are not putting them in a rigid framework, where your input is restricted. This can change over time in a quick and simple manner.

IAD in detail


Low-Code: Quickly build applications to optimize any process across people with virtually no code. Battle tested and improved for over a decade on a wide range of customer projects.

FAST: Build with fast, clean and light-weight code to minimize platform overhead.

SECURE: Secure by design with built-in fine grained access control per user or application group. Our platform is revised on a regular basis for security flaws by an external security partner.

INTELLIGENT: Intelligent automation enhances process quality, reduces risk and optimizes your operations. Real-time analytics and insights allow you to govern, analyse, and drive the efficiency of your business processes.

OPEN: Components can be easily customized to the needs of every project, providing ultimate flexibility. With the full power of the .NET Framework and access to all of our source code, you are never locked in.
