2.1Important concepts in Talend Open Studio

When working with Talend Open Studio, you will often come across words such as repository, project, workspace, job, component and item.

Understanding the concept behind each of these words is crucial to grasping the functionality of Talend Open Studio.

What is a repository? A repository is the storage location Talend Open Studio uses to gather data related to all of the technical items that you use either to describe business models or to design Jobs. Talend Open Studio can connect to as many local repositories as needed. For more information, see How to access one or multiple Repositories on page 10.

What is a project? Projects are structured collections of technical items and their associated metadata. All of the Jobs and business models you design are organized in Projects.

You can create as many projects as you need in a repository. For more information about projects, see Working with projects on page 13.

What is a workspace? A workspace is the directory where you store all your project folders. You need to have one workspace directory per connection (repository connection). Talend Open Studio enables you to connect to different workspace directories, if you do not want to use the default one. For more information about workspaces, see Working with different workspace directories on page 11.What is a job: A job is a graphical design, of one or more components connected together, that allows you to set up and run dataflow management processes. It translates business needs into code, routines and programs. Jobs address all of the different sources and targets that you need for data integration processes and all other related processes.

For detailed information about how to design data integration processes in Talend Open Studio, see Designing a data integration Job on page 57.

What is a component: A component is a preconfigured connector used to perform a specific data integration operation, no matter what data sources you are integrating: databases, applications, flat files, Web services, etc. A component can minimize the amount of hand-coding required to work on data from multiple, heterogeneous sources.

Components are grouped in families according to their usage and displayed in the Palette of the Talend Open Studio main window.

For detailed information about components types and what they can be used for, see the Talend Open Studio Reference Guide.

What is an item: An item is the fundamental technical unit in a project. Items are grouped, according to their types, as: Job Design, Business model, Context, Code, Metadata, etc. One item can include other items. For example, the business models and the Jobs you design are items, metadata and routines you use inside your Jobs are items as well.
