One of the ways to integrate with external systems is using the Extract, Transform, Load (ETL) system. The ETL system creates databases which can be accessed directly by 3rd party tools and solutions. It also allows scheduled execution of transformation scripts on the Data Center Operation server. Together this gives the ability to extract and enter data on the Data Center Operation server.
Based on the ETL system, it is possible to develop custom solutions, integrating DCO with a broad range of data sources.
