# Applicable Scenario for DM

__*DM Application scenario*__

+ Migrating synchronized data from a MySQL-compatible database
+ Synchronizing source library tables with target library heterogeneous tables
+ Merge and synchronize sharded databases
  
-------------------------------------------------------------
1. Migrating synchronized data from a MySQL-compatible database
      TiDB Data Migration (DM) supports in full volume loading and incremental synchronization of data from MySQL-compatible databases.
2. Migration of source library tables and target library heterogeneous tables
 You can synchronize heterogeneous data tables of the source library and the target library through the corresponding configuration. For example, the target library table column contains the source library table scenario.
3. Merge and migration sharded databases
If the source library adopts a table-sharded library architecture design, then we can import the sharded tables of the source library into a table in the target library through TiDB Data Migration (DM).
