Create a new account (say, servicesql) or use any internal SQL account or Active Directory account (e.g., service account to be used with Indeed CM: servicecm). After the database is created, this account would possess db_owner, public privileges and shall be used by the system to perform read/write operations from/to the database.
The database name and its connection settings are to be specified in the configuration files of Indeed AirCard Enterprise system later on.
