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.

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.

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.

Peewee is a simple and small ORM (object-relation mapping) tool. Peewee handles converting between pythonic values and those used by databases, so you can use Python types in your code without having to worry. It has built-in support for sqlite, mysql and postgresql. If you already have a database, you can autogenerate peewee models using pwiz, a model generator.

SQLiteStudio is desktop application for browsing and editing SQLite database files. It is aimed for people, who know what SQLite is, or what relational databases are in general.

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.

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.

Unixodbc is a library providing an API with which to access data sources. Data sources include SQL Servers and any software with an ODBC Driver.

The libdbi-drivers library provides the database specific drivers for the libdbi framework.

The drivers officially supported by libdbi are:

• MySQL,

• PostgreSQL,

• SQLite.

This package provides a Python interface to the Redis key-value store.

Alembic is a lightweight database migration tool for usage with the SQLAlchemy Database Toolkit for Python.

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.

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

Because the many-to-many relationships are not real relationships, they can not be introspected with DBIx::Class. Many-to-many relationships are actually just a collection of convenience methods installed to bridge two relationships. This DBIx::Class component can be used to store all relevant information about these non-relationships so they can later be introspected and examined.

This package provides two scripts that will backup PostgreSQL databases in a cluster. They are supposed to be run in scheduled jobs. pg_backup.sh runs regular backups, pg_backup_rotated.sh runs rotated backups.

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

Yoyo is a database schema migration tool. Migrations are written as SQL files or Python scripts that define a list of migration steps.

Sqlparse is a non-validating SQL parser for Python. It provides support for parsing, splitting and formatting SQL statements.

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.

This package works in conjunction with InflateColumn::DateTime to automatically set update and create date and time based fields in a table.

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