Decoupled Development

dcupl is a Rapid Web Development platform that prioritizes efficient and future-proof digital service development. Through seamless integration with existing backend data, dcupl enables the creation of innovative solutions and optimal preparation for future challenges.

dcupl was designed to enhance the efficiency of developing complex digital services based on various source systems. While systems like SAP are good at storing data reliably, they often lack the necessary performance to deliver the data for powerful and modern digital services.

With dcupl, an innovative technology is available that normalizes and models data early on in projects. This allows for the advancement of frontend application development well before IT can ensure the provision of data through interfaces in the required capacity and performance.

List handling built for efficiency

dcupl follows best practice implementation patterns and ensures high-performance list functionality.

Basic filtering

Called basic, but filtering thousands of elements, with counting results and avoiding “0 results sets”.

Advanced filtering

Combining filters, filtering by dynamic values, suggesting results upfront, etc … creating an excellent user experience.


Numbers always need a context. Grouping elements and processing operations like sum, average or distinct help enormously in a data-driven world.


Grouping entries and operating complex filtering, sorting and aggregations on individual items.


Order matters. Arranging items systematically against each other by combined attributes.


Same things together. Group items on multiple levels by simple rules or common attributes.


Bring order into life. Thousands of attributes are not always required for getting the right information in time. Based on model properties individual views support clearance in the code.

Your central data cockpit

The dcupl Console is the administration cockpit, the central tool for developers and business users to check the data quality and test the behaviour of various configurations - in advance, before the actual implementation of the application begins.


Leverage dcupl's powerful pre-processing capabilities to seamlessly segment your data both horizontally and vertically, aligning with target models and employing intricate, nested queries. As exemplified in the screen illustration, data can effortlessly be primed for frontend application usage through straightforward transformers, eliminating the necessity for complex backend structures.

The input data undergoes a meticulous read-in process, resulting in a judiciously reduced and transformed version. Harnessing dcupl's cutting-edge search and filter technology, the pre-processing step ensures swift access to precisely tailored data for your application, enhancing efficiency and expediting development.

Continuous Data Quality Testing

dcupl offers an innovative solution that provides businesses with advanced capabilities to monitor their critical business applications from multiple perspectives. Data quality testing is a critical component of data governance because it ensures that data is fit for use.

  • Based on the search and filter technology of dcupl, rules are created with which the respective integrated data are continuously checked for irregularities.
  • If a problem occurs or limit values are exceeded for example, the alerting comes into effect and informs defined user groups.
  • Applications allow data to be divided up in a sensible way so that the development process remains as clear as possible and data is loaded into applications as efficiently as possible.

dcupl Console Features

The dcupl Console is the administration cockpit, the central tool for developers and business users to check the data quality and test the behavior of various configurations - upfront, before starting to implement the actual application itself. The Console provides the following features - more to come soon:

dcupl [Project] Dashboard

The dcupl Dashboard displays a user's projects in a matrix overview. Additional widgets support a quick project start and offer the possibility to join demo projects.

The Project Dashboard is a clearly organised display of information and support relating to the respective project.

dcupl Console - Project Dashboard


dcupl Applications are use case-specific bundles of data models and data resources. Applications are therefore not synonymous with "1 application per business application". Rather, meaningful data packages are formed that are required for specific areas, views or even entire use cases in applications.

Applications allow data to be divided up in a sensible way so that the development process remains as clear as possible and data is loaded into applications as efficiently as possible.

dcupl Console Applications

Application Dashboard

On the Application Dashboard, widgets provide a quick overview of loading times, data volumes and other metadata relating to the application.

With the help of the data widgets, each user can create individual analyses of the data contained in the respective application and visualise them based on different display variants.

dcupl Console Application Dashboard

Data Explorer

The Data Explorer is the central entry point to your data. Long before the data is loaded and displayed in the future application, it can be searched, filtered and checked in the Data Explorer.

The data model provides users with an overview of the integrated data and not just individual islands. This means that the data is loaded and displayed generically based on the data models created with dcupl for the future business application.

Users get a feel for the amount of data and can quickly determine which additional data sources may need to be tapped.

dcupl Console Data Explorer

Model Overview

The Model Overview shows a generic overview of the dcupl data model. The user is given a quick overview of the number of data records and attributes per entity and which data functionalities have been defined in the model descriptions. Attributes, meta information and documentation are displayed in tabular form for each entity.

dcupl Console Model Overview

Model Graph

Just like the Model Overview, the Model Graph is generated generically based on the dcupl data model. In contrast to the Model Overview, the data model is visualised graphically rather than in a table, so that users can quickly get a visual picture of the data and its relationships.

For very large models, the graphical representation can be reduced to individual entities and references to other entities can be resolved step by step.

The model graph also supports the onboarding process for new team members in particular, regardless of whether they are developers or technical leads.

dcupl Console Model Graph

Loader Insights

The Loader Insights represent the central developer tool when it comes to the performance. The loading and processing times of the individual model and data resources are measured and visualised accordingly in diagrams.

Developers can use Loader Insights to find and eliminate specific performance bottlenecks.

dcupl Console Loader Insights

Quality Analyzer

The Quality Analyser checks your data based on the defined data model and lists any problems found for further steps.

This allows you to determine in seconds how complete the data is or whether, for example, attributes have been defined in the model but are not contained in the data or vice versa.

dcupl Console Quality Analyzer

Demo Configurator

The Demo Configurator provides a tool that can be used to create prototype catalogues or overviews based on the defined models in just a few seconds.
