# Default Databases

The installation package will create the databases, add table spaces, and add required users, depending on the database types used.

Database type | Default database name | Purpose
--- | --- | ---
SQL Server | AtlasCopco_ToolsNet_Database | Storage for production data, such as results and traces.
SQL Server - ProtocolServerStore | AtlasCopco_ACDC_ProtocolStore | Storage for controller sequence numbers.
SQLite – ProtocolServerStore | AcdcProtocolServerStoreService | Storage for controller sequence numbers. The SQLite database is self contained within the ProtocolServerStore service. No separate installation is required.

ProtocolServerStore service can use either SQL Server or SQLite.
