python-sql is a library to write SQL queries, that transforms idiomatic python function calls to well-formed SQL queries.

This package provides a Python client library for CrateDB. It implements the Python DB API 2.0 specification and includes support for SQLAlchemy.

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

Libpqxx is a C++ library to enable user programs to communicate with the PostgreSQL database back-end. The database back-end can be local or it may be on another machine, accessed via TCP/IP.

QDBM is a library of routines for managing a database. The database is a simple data file containing key-value pairs. Every key and value is serial bytes with variable length. Binary data as well as character strings can be used as a key or a value. There is no concept of data tables or data types. Records are organized in a hash table or B+ tree.

This module tries to split any SQL code, even including non-standard extensions, into the atomic statements it is composed of.

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.

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.

This package is an implementation of psycopg2 using CFFI.

RocksDB is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database. RocksDB is partially based on LevelDB.

This package provides a library for sending commands and receiving replies to and from a Redis server. It comes with a synchronous API, asynchronous API and reply parsing API. Only the binary-safe Redis protocol is supported.

MyCLI is a command line interface for MySQL, MariaDB, and Percona with auto-completion and syntax highlighting.

TimescaleDB is a database designed to make SQL scalable for time-series data. It is engineered up from PostgreSQL and packaged as a PostgreSQL extension, providing automatic partitioning across time and space (partitioning key), as well as full SQL support.

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.

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

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

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

Datasette is a tool for exploring and publishing data. It helps people take data of any shape or size and publish that as an interactive, explorable website and accompanying API.

hiredis-rb is a Ruby extension that wraps hiredis, a minimalist C client for Redis. Both the synchronous connection API and a separate protocol reader are supported. It is primarily intended to speed up parsing multi bulk replies.

SQL::Translator is a group of Perl modules that converts vendor-specific SQL table definitions into other formats, such as other vendor-specific SQL, ER diagrams, documentation (POD and HTML), XML, and Class::DBI classes. The main focus is SQL, but parsers exist for other structured data formats, including Excel spreadsheets and arbitrarily delimited text files. Through the separation of the code into parsers and producers with an object model in between, it's possible to combine any parser with any producer, to plug in custom parsers or producers, or to manipulate the parsed data via the built-in object model. Presently only the definition parts of SQL are handled (CREATE, ALTER), not the manipulation of data (INSERT, UPDATE, DELETE).

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

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.

MDB Tools is a set of tools and applications to read the proprietary MDB file format used in Microsoft's Access database package. This includes programs to export schema and data from Microsoft's Access database file format to other databases such as MySQL, Oracle, Sybase, PostgreSQL, etc., and an SQL engine for performing simple SQL queries.

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