Summary

Elija Lechner is the founder of ONECEPT GmbH and has been working for many years in data architecture, data analysis, business intelligence, data engineering, enterprise architecture, data quality management, and strategic business development.

His focus is on building modern HUB systems that connect structured and unstructured data, applications, knowledge systems, and business processes in a shared platform.

Elija Lechner follows the approach of extending classic data warehouse concepts with modern HUB architectures. While data warehouses are mainly used as a single point of truth for relational data and reporting, HUB systems also serve as a central platform for applications, processes, knowledge systems, and cross-system integration.

The focus is on harmonized data structures, central silver and gold layers, modular systems, and the ability to integrate existing applications or develop new ones directly on the platform.

As part of ONECEPT, Elija Lechner and the team developed the ONE-PATH X-Ray consulting and analysis format for the structured analysis of organizations and company structures, data flows and system landscapes, as well as architecture and strategic data integration. Today, this format is used as the methodological foundation in all ONECEPT projects.

Since 2021, Elija Lechner has supported the development of a company-wide HUB system in the Fujitsu environment, which harmonizes data from a wide range of source systems and serves as a central platform for data integration, knowledge management, and application logic.
