WFilter database version
WFilter supports database and file-based data storage types. There is no feature difference between the "database version" and "file-based version", except for data storage.
With the database version, you can use certain database tools to backup monitored data or customize sql querys. However, to install WFilter database version, you need to have an available MSSQL or MYSQL database server, while the file-based version is easier to setup.
