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.

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)

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

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

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 Postgres SQL parser as a library.

Pypika-tortoise is a fork of pypika which has been streamlined for its use in the context of tortoise-orm. It removes support for many database kinds that tortoise-orm doesn't need, for example.

This package provides a Postgres SQL parser as a library.

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.

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.

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 contains type stubs and a mypy plugin to provide more precise static types and type inference for SQLAlchemy framework.

This package implements the LSP for SQL.

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.

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 provides aerich, a Python database migrations tool for Tortoise ORM. It can be used both programmatically or as a standalone CLI application.

DBD::SQLite is a Perl DBI driver for SQLite, that includes the entire thing in the distribution. So in order to get a fast transaction capable RDBMS working for your Perl project you simply have to install this module, and nothing else.

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.

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.

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.

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.

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.
