# Projects and Platforms

The platform (if any) associated with a project tells the TopLink runtime what specific type of data source a project uses.

A platform includes options specific to a particular data source, such as binding, use of native SQL, use of batch writing, and sequencing.

A login includes details of data source access, such as authentication, use of connection pools, and use of external transaction controllers. A login owns a platform. For more information about logins, see "Projects and Login".

For projects that do not persist to a data source, a platform is not required. For projects that do persist to a data source, a platform is always required.

In TopLink Workbench, the project type determines the type of platform that the project uses, if applicable.

There is a platform type for each project type that persists to a data source. For a complete list of platform types available, see "Data Source Platform Types".
