SCM Concepts and Repository Concepts
To
set the stage for the remainder of the course, you'll need to understand
how the SCM concepts explained here align with the Oracle Repository features
covered in other lessons. While you may often see a corresponding SCM
process, some functions may support other activities.
Environment Setup
During environment setup, you'll create the following repository structures:
| Workarea | A virtual desktop that allows you to see only those object versions in which you are interested. |
| Container | A holding structure for objects. There are two types: application systems and folders. Application systems were used in versions of Oracle Designer before 6i. Folders are mapped to files in the file system. |
| Access Rights | You assign repository users access to workareas and containers based on their project role and responsibilities |
Version Control
To implement version control, you use the following repository functionality:
| Checkin/Checkout | You create object versions using the checkin feature. Once checked in, you must check out an object to modify it. |
| Compare/Merge | The Compare utility identifies the difference between versions of the same object. You combine versions of objects into a single new object version using the Merge utility. |
Release and Promotion Management
To support release and promotion management, you use a repository object called a configuration.
You can manage parallel development by creating branches in the repository.
| Branch | Versions of an object in a version tree may not just be part of a 'trunk', but may be in a branch. In fact, a version tree can have several branches that represent either a permanent parallel stream or a temporary branching. |
Dependency Management
Dependency management is supported by the repository tool called the Dependency Manager.
