Due to its modular design, PAPILLON AFIS can be easily scaled and adapted to any customer-specific requirements – from small laptop-based applications to nationwide, geographically-distributed installations implementing the ‘Central Site + remote stations’ concept.
The server software runs under the Linux operating system. Developed with the Qt widget toolkit, the client software is designed as a cross-platform application to be run on both Linux and Windows. UTF-8 is used as a default character encoding which makes the localization to other languages fast and easier, avoiding the need of code page switching.
In large-scale systems, the server’s jobs such as data acceptance and storage, searches and communication are distributed between:
- Main AFIS server and matchers
- Data storage subsystem
- Communication server
- Express ID check server and matchers
In case of a system with modest throughput requirements, the server’s functions can be distributed among workstations.
The data storage subsystem comprises a requisite number of disk storage units and an Oracle server which is used to extract demographic data from the AFIS database and to keep them in a separate database that is open for interacting with external SQL systems over web browsers.
PAPILLON AFIS is available in a wide variety of hardware configurations, depending on a rated database size, expected throughput capacity and the number of remote terminals that will communicate with the AFIS to request services.
When designing new projects, only most reliable equipment produced by reputed manufacturers and the latest achievements in data storage, information security and process control are used.
Twenty-four-hour unattended operation is made possible owing to the fault-tolerant technologies which allow for redundancy of critical components and enable automatic data backup.
PAPILLON’s backup strategy ensures automatic recovery of databases and search results after any event of data loss and in cases of emergency including power blackouts.
