Tells how to recycle the databases in the databasename pool, when Log-switch item triggers a change of active database.

• None (no database pooling) - reuse existing database name.
  The current database is renamed by appending its creation date and time to its name, and a new database is created having same name as before, or named according to the value of Log-switch new database name item.
  When strategy is None, the Log-switch databasename pool is ignored.
• Sliding (first always active) - means that the first database in the pool always is the active, a switch simply shifts the history of the first to second, second to third and last to nothing.
  When strategy is Sliding, the Log-switch databasename pool must contain at least one database name.
• Circular (next in pool active) - means that the next database in the pool will set as the active when a switch is triggered.
  When strategy is Circular , the Log-switch databasename pool must contain at least one database name.

Set to an item that will control when active log/database is switched.

If ie. the current database will be renamed, set in read-only mode and a new database will be started. If set to a boolean item; log switches when value toggles 'false' to 'true'. If set to a non-boolean item; log switches when value changes.

This property determines how data logged by this module, is stored to the database:

• Sampled
  Stores data, without quality info, at a regular time interval given by Resolution
• Sampled with quality
  Stores data, with quality info, at a regular time interval given by Resolution
• Eventbased with quality
  Stores data, with quality and timestamp info, whenever data (Value, quality or timestamp) changes. The data is scanned for changes at a regular time interval, given by Resolution
