The goal for nanodbc is to make developers happy by providing a simpler and less verbose API for working with ODBC. Common tasks should be easy, requiring concise and simple code.

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.

This package provides an Emacs major mode rec-mode for working with GNU Recutils text-based, human-editable databases. It supports editing, navigation, and querying of recutils database files including field and record folding.

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.

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.

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).

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

Sqlitebrowser lets you create, design, and edit database files compatible with SQLite using a graphical user interface.

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 contains bindings for the ADBC Driver Manager, as well as a DBAPI 2.0/PEP 249-compatible interface on top. This can be used to load ADBC drivers at runtime and use them from Python. Backend-specific packages like adbc_driver_postgresql wrap this package in a more convenient interface, and should be preferred where they exist.

Sqitch is a standalone change management system for database schemas, which uses SQL to describe changes.

An SQL to OO mapper with an object API inspired by Class::DBI (with a compatibility layer as a springboard for porting) and a resultset API that allows abstract encapsulation of database operations. It aims to make representing queries in your code as perl-ish as possible while still providing access to as many of the capabilities of the database as possible, including retrieving related records from multiple tables in a single query, "JOIN", "LEFT JOIN", "COUNT", "DISTINCT", "GROUP BY", "ORDER BY" and "HAVING" support.

Cassandra Cluster Manager is a development tool for testing local Cassandra clusters. It creates, launches and removes Cassandra clusters on localhost.

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.

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

DBIx::Class::DeploymentHandler is a tool for deploying and upgrading databases with DBIx::Class. It is designed to be much more flexible than DBIx::Class::Schema::Versioned, hence the use of Moose and lots of roles.

Sequeler is a native Linux SQL client built in Vala and Gtk. It allows you to connect to your local and remote databases, write SQL in a handy text editor with language recognition, and visualize SELECT results in a Gtk.Grid Widget.

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

This package adds the support of pgvector vectors to Tortoise-ORM as a new type of fields, it helps to filter/order by cosine similarity distances for scementic search using embeddings.

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.

Automatically set and update fields with values calculated at runtime. Ipdate or create actions will set the specified columns to the value returned by the callback you specified as a method name or code reference.

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

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.
