Administration - Administration: Database

The database stores all recordings, transcripts, user account details, rules, typing pool details, etc., therefore the active database file should be backed up regularly.

The location of the database file will normally be:

For Windows XP: C:\Documents and Settings\All Users\Application Data\NCH Software\Delegate\database.db
For Windows Vista / 7: C:\ProgramData\NCH Software\Delegate\database.db

If / when a backed up database is restored, and the latest back up was taken before the creation of the most recent dictations, please be aware that client programs such as Express Scribe may assume that those dictations have been deleted from the server.

The database schema version is used to track changes to the format of the data in the database. Some features of Express Delegate require a minimum database schema version to function.

When upgrading or downgrading Express Delegate, or when restoring a database from a back-up, one of the following warning messages may appear in the log:

Database uses a superseded schema version
This means that the database was created with an earlier version of Express Delegate and that the schema version used in the current version of Express Delegate is higher. Express Delegate is backwards compatible with databases created in earlier versions and will continue to operate, however there may be new features that require the latest schema version and will therefore not be available. See Options: Database for details about updating the schema version.
Database uses a potentially incompatible schema version
This means that the database was created with a later version of Express Delegate and that the schema version used in the current version of Express Delegate is lower. Express Delegate is not guaranteed to be forwards compatible with databases created in later versions, and may operate incorrectly, possibly causing data corruption.
