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 library provides a Pythonic API wrapper for the reference Arrow C++ implementation, along with tools for interoperability with pandas, NumPy, and other traditional Python scientific computing packages.

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.

This package provides an improved fork of python-aioodbc, and makes it possible to Access ODBC databases with python-asyncio.

TinyDB is a small document oriented database written in pure Python with no external dependencies. The targets are small apps that would be blown away by a SQL-DB or an external database server.

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

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.

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.

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

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.

This library implements a database independent abstraction layer in C, similar to the DBI/DBD layer in Perl. Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework.

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).

This package provides a MySQL driver for the Perl5 Database Interface (DBI).

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.

PyPika is a python SQL query builder that exposes the full richness of the SQL language using a syntax that reflects the resulting query.

MySQL::Config emulates the load_defaults function from libmysqlclient. It will fill an array with long options, ready to be parsed by Getopt::Long.

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

This package provides a database interface for Perl.

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

UnQLite is an in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine. UnQLite is a document store database similar to Redis, CouchDB, etc., as well as a standard key/value store similar to BerkeleyDB, LevelDB, etc.

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

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

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.
