DataArts Studio provides basic and incremental packages. If the basic package cannot meet your demands, you need to create an incremental package.

Table 1 lists the incremental packages provided by DataArts Studio.

**Table 1** Incremental packages
Package Type	Description	Scenario
DataArts Migration incremental package	A DataArts Migration (that is, CDM) incremental package provides resources for a CDM cluster. When you create a CDM incremental package, the system automatically creates a CDM cluster based on the specifications you select for the incremental package. CDM clusters can be used in the following scenarios: Data migration jobs can be created and run in CDM clusters to migrate data to the cloud or import data to the data lake. CDM clusters can be used as agents of data connections in Management Center, which enable communications between DataArts Studio instances and data sources.	A DataArts Studio instance does not contain CDM clusters. To use CDM clusters, create DataArts Migration incremental packages.
