This package provides a Ruby client that tries to match Redis' API one-to-one, while still providing an idiomatic interface.

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

lmdbxx is a comprehensive C++ wrapper for the LMDB embedded database library, offering both an error-checked procedural interface and an object-oriented resource interface with RAII semantics.

This module provides connection pool implementations that can be used with the psycopg PostgreSQL driver.

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.

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.

litecli is a command-line client for SQLite databases that has auto-completion and syntax highlighting.

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 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.

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

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.

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.

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.

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

pg_tmp creates temporary PostgreSQL databases, suitable for tasks like running software test suites. Temporary databases created with pg_tmp have a limited shared memory footprint and are automatically garbage-collected after a configurable number of seconds (the default is 60).

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.

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

DBIx::Simple provides a simplified interface to DBI, Perl's powerful database module. This module is aimed at rapid development and easy maintenance. Query preparation and execution are combined in a single method, the result object (which is a wrapper around the statement handle) provides easy row-by-row and slurping methods.

The DB::File module provides Perl bindings to the Berkeley DB version 1.x.

aiomysql is a driver for accessing a MySQL database from the asyncio Python framework. It depends on and reuses most parts of PyMySQL. aiomysql tries to preserve the same API as the aiopg library.

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

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.

Package rdb implements parsing and encoding of the Redis RDB file format.

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