Frequently an organization will find that the same resources are used in multiple ETL applications, for example, the same database, general purpose processing logic, or file system locations. Creating an easy way to reuse these resources across multiple applications would increase efficiency and reduce errors. Moreover, not every ETL developer has the same skill set, and it is likely that one developer will be more adept at writing code while another is more comfortable configuring database connections. Real productivity gains will come when these developers are able to work independently while still making their work available to others assigned to the same project. These are the benefits of a centralized version control system.
