PyDBISAM is a pure Python module to read and export data from DBISAM tables (from their .dat files). The scope of PyDBISAM is not to provide a full database framework but merely to provide the ability to read the table structure and the raw table data.
DBISAM is an on-disk database with one file per table. The file format is proprietary. The basic structure is documented here.
PyDBISAM includes a simple CLI that can be used to dump the table structure or export the data to various formats (e.g.: CSV).
# pydbisam --dump-structure path/to/file.dat
# pydbisam --dump-csv path/to/file.datThe PyDBISAM class can be used for read-only access to the tables.
from pydbisam import PyDBISAM
with PyDBISAM("path/to/file.dat") as db:
print(", ".join(db.fields()))
for row in db.rows():
print(", ".join(map(str, row)))- DBISAM-to-JSON
- Python 2/3 script to convert DBISAM to JSON (limited support for various column types).
