libMemcached is a library to use memcached in C/C++ applications. It comes with a complete reference guide and documentation of the API, and provides features such as:

• Asynchronous and synchronous transport support

• Consistent hashing and distribution

• Tunable hashing algorithm to match keys

• Access to large object support

• Local replication

TDB is a Trivial Database. In concept, it is very much like GDBM, and BSD's DB except that it allows multiple simultaneous writers and uses locking internally to keep writers from trampling on each other. TDB is also extremely small.

Kyoto Cabinet is a standalone file-based database that supports Hash and B+ Tree data storage models. It is a fast key-value lightweight database and supports many programming languages. It is a NoSQL database.

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

MySQL is a fast, reliable, and easy to use relational database management system that supports the standardized Structured Query Language.

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 implements the LSP for SQL.

DBD::SQLite is a Perl DBI driver for SQLite, that includes the entire thing in the distribution. So in order to get a fast transaction capable RDBMS working for your Perl project you simply have to install this module, and nothing else.

Databases provides a wrapper around asynchronous database libraries with SQLALchemy.

This package provides job scheduling capabilities to python-rq (Redis Queue).

Tokyo Cabinet is a library of routines for managing a database. The database is a simple data file containing records, each is a pair of a key and a value. Every key and value is serial bytes with variable length. Both binary data and character string can be used as a key and a value. There is neither concept of data tables nor data types. Records are organized in hash table, B+ tree, or fixed-length array.

This package provides custom SQLite functions written in Python for ranking documents indexed using the SQLite's FTS4 full text search extension.

This package provides Guile bindings to the WiredTiger ``NoSQL'' database.

psycopg2 is a thread-safe PostgreSQL adapter that implements DB-API 2.0.

This package provides a vector similarity search extension for Postgres. Store your vectors with the rest of your data. It supports:

• exact and approximate nearest neighbor search;

• L2 distance, inner product, and cosine distance;

• any language with a Postgres client.

Apache Arrow is a columnar in-memory analytics layer designed to accelerate big data. It houses a set of canonical in-memory representations of flat and hierarchical data along with multiple language-bindings for structure manipulation. It also provides IPC and common algorithm implementations.

This package contains type stubs and a mypy plugin to provide more precise static types and type inference for SQLAlchemy framework.

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.

This package provides a Postgres SQL parser as a library.

MySQLdb is an interface to the popular MySQL database server for Python. The design goals are:

1. Compliance with Python database API version 2.0 [PEP-0249],

2. Thread-safety,

3. Thread-friendliness (threads will not block each other).

This package provides a lightweight wrapper around the sqlite3 database with a simple, Pythonic dict-like interface and support for multi-thread access.

This package provides aerich, a Python database migrations tool for Tortoise ORM. It can be used both programmatically or as a standalone CLI application.

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

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.
