Firebird is an SQL RDBMS with rich support for ANSI SQL (e.g., INSERT...RETURNING) including UDFs and PSQL stored procedures, cursors, and triggers. Transactions provide full ACID-compliant referential integrity.

The database requires very little manual maintenance once set up, making it ideal for small business or embedded use.

When installed as a traditional local or remote (network) database server, Firebird can grow to terabyte scale with proper tuning---although PostgreSQL may be a better choice for such very large environments.

Firebird can also be embedded into stand-alone applications that don't want or need a full client & server. Used in this manner, it offers richer SQL support than SQLite as well as the option to seamlessly migrate to a client/server database later.

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.

Valkey is a high-performance key-value datastore that supports a variety of workloads such as caching, message queues, and can act as a primary database.

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

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.

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.

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.

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

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

Tortoise ORM is an easy-to-use asyncio ORM (Object Relational Mapper) inspired by Django. Tortoise ORM was built with relations in mind and admiration for the excellent and popular Django ORM. It's engraved in its design that you are working not with just tables, you work with relational data.

Test::PostgreSQL automatically setups a PostgreSQL instance in a temporary directory, and destroys it when the perl script exits.

This module creates a temporary SQLite database, deploys a DBIC schema, and then connects to it. This lets you easily test DBIC schema. Since you have a fresh database for every test, you don't have to worry about cleaning up after your tests, ordering of tests affecting failure, etc.

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.

dicedb is a fast, reactive, in-memory database optimized for modern hardware. Commonly used as a cache, it offers a familiar interface while enabling real-time data updates through query subscriptions. It delivers higher throughput and lower median latencies, making it ideal for modern workloads.

pylibmc is a client in Python for memcached. It is a wrapper around TangentOrg’s libmemcached library, and can be used as a drop-in replacement for the python-memcached library.

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.

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.

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

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

This module was inspired by the excellent DBIx::Abstract. While based on the concepts used by DBIx::Abstract, the concepts used have been modified to make the SQL easier to generate from Perl data structures. The underlying idea is for this module to do what you mean, based on the data structures you provide it, so that you don't have to modify your code every time your data changes.

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.

FreeTDS is an implementation of the Tabular DataStream protocol, used for connecting to MS SQL and Sybase servers over TCP/IP.

asyncpg is a database interface library designed specifically for PostgreSQL and Python/asyncio. asyncpg is an efficient, clean implementation of PostgreSQL server binary protocol for use with Python's asyncio framework.
