I Am Learning Basics Of Talend And Can You Explain Why Is Talend Called A Code Generator?

When a job is executed, the data is translated into java class at the backend automatically using Talend studio. This is very user-friendly, where it needs to drag and drop the components to design a job, and the rest of the work is done in the backend. Then a Java Code is generated by dividing the job into three sub-parts naming end, main and begin respectively.
