Data migration from one database to another: This is a common scenario when new systems are implemented or existing systems are upgraded. Data has to be populated into the new or upgraded system and database schemas may be subtly or completely different, requiring some modification of the data prior to loading. Data migrations tend to be “one-off” activities, not integrations that are deployed on an ongoing basis. The Studio facilitates data migrations through its many database connectors and actions.
Regular file exchanges between systems: The humble flat file is still a cornerstone of many systems integrations. Their low-tech approach makes them particularly suitable for batch processes when real-time data flows are unnecessary. File exchanges will often require some form of file transformation, either data content, data format, or both. The Studio has the ability to manage many different file formats and, with its file management capabilities such as FTP and archiving (zipping), is able to facilitate a full end-to-end file exchange process.
Data synchronization: Enterprises often have multiple data repositories of the same data. For example, data about customers might reside in the CRM system, the finance system, and the distribution system. They will probably have similar but different data models across these systems and every time a change is made in one, the same change needs to be made in the others—typically a time-consuming and manual process. The Studio can be used to keep the data in sync across systems with jobs that automate and transform the data transfer.
ETL (Extract, Transform, and Load): A key component process of a data warehouse or business intelligence system, ETL processes extract data from operational systems, transform the data, applying a series of rules or functions, and load the data into a database or data warehouse system.
TALEND PRODUCT PORTFOLIO
As you might expect, for such a critical systems-development activity, there is no end of options to choose from to fulfill the need. From complex multi-million dollar integration suites from the major systems vendors to humble, yet powerful, scripting languages such as Perl, there is something for every budget and taste. So what is Talend Open Studio for Data Integration and why should you consider it for your next integration project?
