This package provides mock helpers for SQLAlchemy that makes it easy to mock an SQLAlchemy session while preserving the ability to do asserts.

Normally Normally SQLAlchemy's expressions cannot be easily compared as comparison on binary expression produces yet another binary expression, but this library provides functions to facilitate such comparisons.

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).

This package provides a CLI tool and Python utility functions for manipulating SQLite databases. It's main features are:

• Pipe JSON (or CSV or TSV) directly into a new SQLite database file, automatically creating a table with the appropriate schema.

• Run in-memory SQL queries, including joins, directly against data in CSV, TSV or JSON files and view the results.

• Configure SQLite full-text search against your database tables and run search queries against them, ordered by relevance.

• Run transformations against your tables to make schema changes that SQLite ALTER TABLE does not directly support, such as changing the type of a column.

• Extract columns into separate tables to better normalize your existing data.

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

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.

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

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

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.

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.

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

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.

fastparquet is a Python implementation of the Parquet file format. fastparquet is used implicitly by dask, pandas and intake-parquet. It supports the following compression algorithms:

• Gzip

• Snappy

• Brotli

• LZ4

• Zstd

• LZO (optionally)

SOCI is an abstraction layer for several database backends, including PostreSQL, SQLite, ODBC and MySQL.

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

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.

SQLAlchemy is the Python SQL toolkit and ORM that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

asyncmy is a fast asyncio MySQL driver, which reuses most of pymysql and aiomysql but rewrites the core protocol with Cython for performance.

SQLCipher is an implementation of SQLite, extended to provide transparent 256-bit AES encryption of database files. Pages are encrypted before being written to disk and are decrypted when read back. It’s well suited for protecting embedded application databases and for mobile development.

SDB is a simple key/value database based on djb's cdb disk storage that supports JSON and array introspection.

Virtuoso is a scalable cross-platform server that combines relational, graph, and document data management with web application server and web services platform functionality.

This Python package provides an API to execute meta-commands (AKA "special", or "backslash commands") on PostgreSQL.

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

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.

Kyoto Cabinet is a standalone file-based database that supports Hash and B+ Tree data storage models. It is a fast key-value lightweight database and supports many programming languages. It is a NoSQL database.
