Darwin's cctools are a set of tools somewhat similar in purpose to GNU Binutils, but for Mach-O files targeting Darwin. The suite includes install_name_tool, dyldinfo, and other specialized tools in addition to standard utilities like ld and as. This package provides portable versions of the tools.

GDL (GNU Data Language) is an incremental compiler compatible with IDL (Interactive Data Language) and to some extent with PV-WAVE. Together with its library routines it serves as a tool for data analysis and visualization in such disciplines as astronomy, geosciences and medical imaging.

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.

Psycopg 3 is a new implementation of the popular psycopg2 database adapter for Python.

python-pyodbc provides a Python DB-API driver for ODBC.

This package provides an asynchronous client for SQLite using AnyIO.

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.

dogpile.cache is a caching API which provides a generic interface to caching backends of any variety, and additionally provides API hooks which integrate these cache backends with the locking mechanism of dogpile.

Redis is an advanced key-value cache and store. Redis supports many data structures including strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs.

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.

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 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.

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.

This package provides tooling for solid, persistent and pooled connections to a database that can be used in all kinds of multi-threaded environments.

dicedb is a fast, reactive, in-memory database optimized for modern hardware. Commonly used as a cache, it offers a familiar interface while enabling real-time data updates through query subscriptions. It delivers higher throughput and lower median latencies, making it ideal for modern workloads.

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

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.

python-lmdb or py-lmdb is a Python binding for the Lightning Memory-Mapped Database (LMDB), a high-performance key-value store.

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).

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

This package provides a utility for dumping the contents of an ElasticSearch index to a compressed file and restoring the dumpfile back to an ElasticSearch server

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.

Memcached is an in-memory key-value store. It has a small and generic API, and was originally intended for use with dynamic web applications.

Sparql-query is a command-line tool for accessing SPARQL endpoints over HTTP. It has been intentionally designed to feel similar to tools for interrogating SQL databases. For example, you can enter a query over several lines, using a semi-colon at the end of a line to indicate the end of your query. It also supports readline so that you can more easily recall and edit previous queries, even across sessions. It can be used non-interactively, for example from a shell script.
