SQLiteStudio is desktop application for browsing and editing SQLite database files. It is aimed for people, who know what SQLite is, or what relational databases are in general.

This package provides a program to build Entity Relationship diagrams from a SQLAlchemy model (or directly from the database).

PyPika is a python SQL query builder that exposes the full richness of the SQL language using a syntax that reflects the resulting query.

Pebble is a LevelDB/RocksDB inspired key-value store focused on performance and internal usage by CockroachDB. Pebble inherits the RocksDB file formats and a few extensions such as range deletion tombstones, table-level bloom filters, and updates to the MANIFEST format. This package provides command line interface (CLI).

This library provides a Pythonic API wrapper for the reference Arrow C++ implementation, along with tools for interoperability with pandas, NumPy, and other traditional Python scientific computing packages.

This package provides a utility for dumping the contents of an ElasticSearch index to a compressed file and restoring the dumpfile back to an ElasticSearch server

PostgreSQL is a powerful object-relational database system. It is fully ACID compliant, has full support for foreign keys, joins, views, triggers, and stored procedures (in multiple languages). It includes most SQL:2008 data types, including INTEGER, NUMERIC, BOOLEAN, CHAR, VARCHAR, DATE, INTERVAL, and TIMESTAMP. It also supports storage of binary large objects, including pictures, sounds, or video.

fastparquet is a Python implementation of the Parquet file format. fastparquet is used implicitly by dask, pandas and intake-parquet. It supports the following compression algorithms:

• Gzip

• Snappy

• Brotli

• LZ4

• Zstd

• LZO (optionally)

Psycopg 3 is a new implementation of the popular psycopg2 database adapter for Python.

The libdbi-drivers library provides the database specific drivers for the libdbi framework.

The drivers officially supported by libdbi are:

• MySQL,

• PostgreSQL,

• SQLite.

WiredTiger is an extensible platform for data management. It supports row-oriented storage (where all columns of a row are stored together), column-oriented storage (where columns are stored in groups, allowing for more efficient access and storage of column subsets) and log-structured merge trees (LSM), for sustained throughput under random insert workloads.

RQ (Redis Queue) is a simple Python library for queueing jobs and processing them in the background with workers. It is backed by Redis and it is designed to have a low barrier to entry.

This library implements a database independent abstraction layer in C, similar to the DBI/DBD layer in Perl. Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework.

PyMySQL is a pure-Python MySQL client library, based on PEP 249. Most public APIs are compatible with mysqlclient and MySQLdb.

lmdbxx is a comprehensive C++ wrapper for the LMDB embedded database library, offering both an error-checked procedural interface and an object-oriented resource interface with RAII semantics.

This package provides two scripts that will backup PostgreSQL databases in a cluster. They are supposed to be run in scheduled jobs. pg_backup.sh runs regular backups, pg_backup_rotated.sh runs rotated backups.

Databases provides a wrapper around asynchronous database libraries with SQLALchemy.

SDB is a simple key/value database based on djb's cdb disk storage that supports JSON and array introspection.

This module provides connection pool implementations that can be used with the psycopg PostgreSQL driver.

The MariaDB Connector/C is used to connect applications developed in C/C++ to MariaDB and MySQL databases.
