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 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.

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).

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.

SQL::Tokenizer is a tokenizer for SQL queries. It does not claim to be a parser or query verifier. It just creates sane tokens from a valid SQL query.

DBIx::Simple provides a simplified interface to DBI, Perl's powerful database module. This module is aimed at rapid development and easy maintenance. Query preparation and execution are combined in a single method, the result object (which is a wrapper around the statement handle) provides easy row-by-row and slurping methods.

MySQL is a fast, reliable, and easy to use relational database management system that supports the standardized Structured Query Language.

The package aiosqlite replicates the standard sqlite3 module, but with async versions of all the standard connection and cursor methods, and context managers for automatically closing connections.

FreeTDS is an implementation of the Tabular DataStream protocol, used for connecting to MS SQL and Sybase servers over TCP/IP.

RocksDB is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database. RocksDB is partially based on LevelDB.

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.

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

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.

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

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

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.

pgloader is a program that can load data or migrate databases from CSV, DB3, iXF, SQLite, MS-SQL or MySQL to PostgreSQL.

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.

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

APSW is a Python wrapper for the SQLite embedded relational database engine. In contrast to other wrappers such as pysqlite it focuses on being a minimal layer over SQLite attempting just to translate the complete SQLite API into Python.

Libpqxx is a C++ library to enable user programs to communicate with the PostgreSQL database back-end. The database back-end can be local or it may be on another machine, accessed via TCP/IP.

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

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.

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