ASE-DB backends
Decision gist · record as of 2026-08-14
Yes, if you need ASE to store data in a specific database system (PostgreSQL, MySQL, or LMDB) rather than ASE's default format. Install friction is low and no known vulnerabilities exist. However, verify the license terms first, and be aware that the package is aging—last release was 275 days ago—so check whether it still supports your target database versions before committing to production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; also requires a running database server (PostgreSQL, MySQL, or LMDB) and appropriate credentials or file path.
- Low install friction with a pure-Python wheel distribution.
- Maintenance status is aging—last release was 275 days ago—so expect limited active development and slower response to issues.

What it is and what it does
ase-db-backends extends ASE with pluggable database storage options. It allows users to persist atomic structures and simulation results to PostgreSQL, MySQL, or LMDB instead of using ASE's default storage, enabling integration with existing database infrastructure and supporting collaborative or large-scale computational workflows.
The package depends on ase, numpy, and database drivers (psycopg2-binary for PostgreSQL, pymysql for MySQL, lmdb for the embedded option), plus cryptography for secure connections. It requires Python 3.10 or later and is distributed as a pure-Python wheel, making installation straightforward across platforms.
Use it for
- Store ASE atomic structures in PostgreSQL for shared access across a research team or computing cluster
- Archive large numbers of simulation results in MySQL with structured queries for post-processing
- Use LMDB as a fast, embedded database for local caching of intermediate simulation data
- Integrate ASE workflows with existing database infrastructure in a computational chemistry pipeline
- Enable reproducible research by persisting atomic configurations and metadata to a queryable backend
