Design Time Repository

The Design Time Repository (DTR) is the repository of the SAP NetWeaver Development Infrastructure (NWDI). You use it to store files and folders. The DTR allows synchronous or asynchronous work of a number of DTR servers in a landscape. You always have consistent versions of a resource, regardless of the DTR servers you use. DTR provides a version history of a resource throughout each workspace in which it is checked out and changed, allowing you to have strong versioning control.

Thus, the DTR manages versioning of your resources and supports concurrent changes of the same resource in the same repository by different users. It provides an infrastructure for managing distributed and large-scale application development that includes mechanisms to propagate resource changes between repositories including change management.

The DTR itself consists of two parts:

• Server

• Client

The DTR server and client parts are clearly separated allowing scalability and reliability of the overall solution. From a logical point of view, the DTR uses files and folders for storage. The client part, installed as part of your development environment, uses the local file system.
