Movement and Transformation

Data movement and transformation with ETL – Extraction, Transformation and Load – or ELT – Extraction, Load and Transforamtion – processes consists of programmatically extracting, transforming and loading data from one or more sources into a target structure.

ETL and ELT processes are a key part of any company’s data management strategy.

To be of value they must be available, and often that means moving them and preparing them for use: that is the purpose of each and every one of these processes.

The ETL stages typically consist of:


Data selection from different sources.


Data transformation, applying business rules.


Data loading at the appropriate destination and validation of results.

Each of these steps is an essential part of the mechanism for keeping the correct data up to date.

We design and implement these processes adapted to your application:
