ETL Service
The ETL (Extract, Transform, Load) service is a specialized subsystem designed to ensure integration with external information systems through automated data exchange, processing, and loading. This service is implemented using Integration Services, which are part of the DBMS used in the system, as well as the open-source tool Pentaho Data Integration (Kettle ETL). This allows for flexible configuration of the processes for extracting, transforming, and loading data according to project requirements, ensuring high performance and scalability.
Main Purpose
Data processing and import — loading information about subscribers from utility and other service-providing organizations into the system.
Data export for service providers — generating and transmitting data, including information about payments made in their favor.
Integration with external sources — retrieving data from external systems, followed by transformation into the required format and structure for storage and analysis.
Loading into the target data storage — saving processed information in the final database, including storage types like Data Store or Data Warehouse, ensuring the ability for further analytics.
