Data service Jobs will simply be referred to as Jobs in the following documentation.
A Job Design is the runnable layer of a business model. It is a graphical design, of one or more components connected together, that allows you to set up and run dataflow management processes. A Job Design translates business needs into code, routines and programs, in other words it technically implements your data flow.
The Jobs you design can address all of the different sources and targets that you need for data integration and data service processes and any other related process.
When you design a Job in Talend Studio, you can:
put in place data integration and data service actions using a library of technical components.
change the default setting of components or create new components or family of components to match your exact needs.
set connections and relationships between components in order to define the sequence and the nature of actions.
access code at any time to edit or document the components in the designed Job.
create and add items to the repository for reuse and sharing purposes (in other projects or Jobs or with other users).
In order to be able to execute the Jobs you design in Talend Studio, you need to install an Oracle JVM 1.8 or OpenJDK 1.8 (IBM JVM is not supported). You can download Oracle JVM from http://www.oracle.com/technetwork/java/javase/downloads/index.html. For more information about OpenJDK, see http://openjdk.java.net/.
