Andmeintegratsioon

Andmeintegratsioon, the Estonian term for data integration, is the process of combining data from multiple sources to provide a unified view for analysis and operations. It encompasses methods, technologies, and governance practices designed to ensure data is accurate, timely, and accessible across the organization. The aim is to enable trustworthy data-driven decision making and streamlined workflows.

Common approaches include ETL (extract-transform-load) and ELT (extract-load-transform), data virtualization, and API-based integration. These methods may process data in batches or in real time, with streaming and event-driven architectures increasingly used to support up-to-date analytics and operational monitoring.

Key components include diverse data sources, an integration layer, and storage systems such as data warehouses and data lakes, supported by metadata management and data lineage. Data quality, governance, and security are integral, especially when handling sensitive information and regulatory requirements.

Applications span finance, retail, manufacturing, healthcare, and public sector domains, where integrated data supports reporting, risk management, customer insight, and operational optimization. The concept aims to provide a single source of truth while enabling flexible analytics and cross-domain workflows.

Challenges include data silos, inconsistent schemas, data quality gaps, latency, and privacy concerns. Trends shaping the field include cloud-based platforms, data fabrics, data meshes, and AI-assisted data mapping to automate integration tasks and improve semantic alignment.
