The [[https://cms.cern/][CMS]] experiment is managing hundreds petabytes of data recorded by 
the detector and simulated physics events. Data are transferred to computing centers, or sites, providing facilities for data storage and 
computing resources for data processing and analysis. 
<br>
!PhEDEx (Physics Experiment Data Export) maintains the knowledge of data 
replicas locations and manages data transfers between the !CMS sites.
<br>
Main !PhEDEx components are: 
   * Central Transfer Management Database (TMDB) maintaining a system state 
   * Agents performing central and local site-specific tasks 
   * Interactive [[https://cmsweb.cern.ch/phedex/][Web Page]] for managing and monitoring the transfers
   * Web [[https://cmsweb.cern.ch/phedex/datasvc/doc][data service]] providing !APIs for integration with other tools
   * Command-line tools for the operations and administrative functions
