DACFx & Import / Export Service

Terminology

Some DefinitionsDAC – Data-tier ApplicationDACFx – DAC FrameworkDACPAC –Schema only artifactBACPAC – Deployment artifact containing schema and data

DAC Fx (DAC Framework)

Client DAC ComponentsDACFX client library installed automatically by SQL ServerNo need for additional client libraries or MSIsWizards provided in SSMS to create and distribute DACPAC/BACPACSimplify packaging and deployment of databases

Import/Export Service

Simplified MigrationImport/Export between Windows Azure SQL Database and Blob StorageExport and Import a logical backup file (BACPAC) containing schema definition and dataCopy databases between SQL Database serversMigrate from SQL Server on-premises to SQL Database

DataData

Transfer Efficiency

Notes

BCP No N/A Yes Good • Efficient transfer of data to existing table

SSMS Generate Scripts wizard

Yes Some Yes Poor• Good for smaller databases• Has explicit option for SQL Database script generation

SQL Server Import & Export Data

No N/A Yes Good• Simple UI on top of SSIS; also available in SSMS

SSIS No N/A Yes Good• Most flexibility

SQL Database Migration Wizard

Yes Yes Yes Good• Great capabilities; e.g. evaluate trace files• Open source on CodePlex;• Not supported by MSFT

DAC (BACPAC) Yes Yes Yes Good• Entity containing all database objects including data• Full SQL Database support

DAC Database Import/Export

Yes Yes Yes Good• Export/import of DAC plus data with DAC framework• Service for cloud-only support coming soon

SQL Database Copy Yes N/A Yes Good• Create transactionally consistent copy of SQL Database

instances• Currently within the same data center
