Talend Open Studio for Data Integration is an open source data integration product developed by Talend and designed to combine, convert and update data in various locations across a business.

Talend Open Studio for Data Integration operates as a code generator, producing data-transformation scripts and underlying programs in Java. Its GUI gives access to a metadata repository and to a graphical designer. The metadata repository contains the definitions and configuration for each job – but not the actual data being transformed or moved. All of the components of Talend Open Studio for Data Integration use the information in the metadata repository.

The product is based on Eclipse RCP. Most of its contributors work for commercial open-source vendor Talend.

Users design individual jobs using graphical components,[5] from a set of over 900, for transformation, connectivity, or other operations. The jobs created can be executed from within the studio or as standalone scripts.

An organization might typically use Talend Open Studio for Data Integration for:

• synchronization or replication of databases
• right-time or batch exchanges of data
• ETL (Extract/Transform/Load) for analytics
• data migration
• complex data transformation and loading
• data quality exercises
• big data

Talend Open Studio for Data Integration primarily differs from Talend Data Integration and Talend Data Management Platform in that the subscription versions have a Subversion plug-in built in for allowing project level change control and supports developer collaboration. There are additional features such as support for joblets (reusable code) as well as data quality components.
