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

This package provides a PostgreSQL driver for the Perl5 Database Interface (DBI).

Databases provides a wrapper around asynchronous database libraries with SQLALchemy.

The Lightning Memory-Mapped Database (LMDB) is a high-performance transactional database. Unlike more complex relational databases, LMDB handles only key-value pairs (stored as arbitrary byte arrays) and relies on the underlying operating system for caching and locking, keeping the code small and simple. The use of ‘zero-copy’ memory-mapped files combines the persistence of classic disk-based databases with high read performance that scales linearly over multiple cores. The size of each database is limited only by the size of the virtual address space — not physical RAM.

This package provides a MySQL driver for the Perl5 Database Interface (DBI).

This package provides a Postgres SQL parser as a library.

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

The drivers officially supported by libdbi are:

• MySQL,

• PostgreSQL,

• SQLite.

ORC is a self-describing type-aware columnar file format designed for Hadoop workloads. It is optimized for large streaming reads, but with integrated support for finding required rows quickly.

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

UnQLite is an in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine. UnQLite is a document store database similar to Redis, CouchDB, etc., as well as a standard key/value store similar to BerkeleyDB, LevelDB, etc.

The package aiosqlite replicates the standard sqlite3 module, but with async versions of all the standard connection and cursor methods, and context managers for automatically closing connections.

This package provides a Postgres SQL parser as a library.

python-lmdb or py-lmdb is a Python binding for the Lightning Memory-Mapped Database (LMDB), a high-performance key-value store.

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.

LevelDB is a fast key-value storage library that provides an ordered mapping from string keys to string values.

Galera is a wsrep-provider that is used with MariaDB for load-balancing and high-availability (HA).

MariaDB is a multi-user and multi-threaded SQL database server, designed as a drop-in replacement of MySQL.

SQLAlchemy-utils provides various utility functions and custom data types for SQLAlchemy. SQLAlchemy is an SQL database abstraction library for Python.

You might also want to install the following optional dependencies:

1. python-passlib

2. python-babel

3. python-cryptography

4. python-pytz

5. python-psycopg2

6. python-furl

7. python-flask-babel

python-pyodbc provides a Python DB-API driver for ODBC.

Yoyo is a database schema migration tool. Migrations are written as SQL files or Python scripts that define a list of migration steps.

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.

SQLAlchemy is the Python SQL toolkit and ORM that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

Fakeredis is a pure-Python implementation of the redis-py Python client that simulates talking to a redis server. It was created for a single purpose: to write unit tests.

Setting up redis is not hard, but one often wants to write unit tests that don't talk to an external server such as redis. This module can be used as a reasonable substitute.
