Dbopen is the library interface to database files. The supported file formats are btree, hashed and UNIX file oriented. The btree format is a representation of a sorted, balanced tree structure. The hashed format is an extensible, dynamic hashing scheme. The flat-file format is a byte stream file with fixed or variable length records. The formats and file format specific information are described in detail in their respective manual pages btree(3), hash(3) and recno(3).
