When exporting separate database the application automatically includes also related databases, with an option to include complete copy or only records that are linked by relation. This format is used for creating backup copies of databases, and for transferring data between different devices. Native FDB file format can contain data from multiple databases and includes complete definition of fields, relations, derived fields and data views. The full version of the application allows importing and exporting data in various file formats. With the full version of application the tables, forms and reports can be printed via system printer on Windows computer or via Google Cloud Print service on Windows Phone device.

Derived fields can be used for filtering, sorting and reporting just like static fields. In addition to static field types the application provides derived fields computed from data values in static fields. The database structure can be altered at any time by adding or removing fields and relations. Aggregated computations such as total or average values of fields in selected records can be shown in report views. The display settings can be selected quickly by the name allowing easy changing of data view perspective. The application displays database records in customizable table and form views that share persistent settings for filtering and sorting. The data can be entered into individual records, or simultaneously into some of the fields of all selected records. The actual data entry can be performed later, when the user can spend more time entering data into data fields in a searchable form based on media captured in the field.

This allows to reduce data collection activity to a few short actions. The main distinguishing feature is ability to attach sound recording or photo to any data field regardless of its type. The design goal of the application is to make a database convenient for collecting data in the field. FDB is a general purpose relational database application for mobile devices.
