Meanwhile, the UNF file extension is also found as the unformatted file for the Btrieve application. The Btrieve application is considered as a transactional database, and contrary to popular belief, it is not an RDBMS or relational database management system. The Btrieve application deals with retrieving data, creating records, data deletion primitives, and updating records. It utilizes the indexed sequential access method or ISAM, for its underlying storage mechanism and indexing. A core component of the Btrieve's application is its utilization of the MicroKernel Database Engine that can enable various database backends for modularization and integration into its developer's DBMS package, which is the Pervasive SQL.
