litecli is a command-line client for SQLite databases that has auto-completion and syntax highlighting.

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).

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.

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.

Test::PostgreSQL automatically setups a PostgreSQL instance in a temporary directory, and destroys it when the perl script exits.

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.

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.

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

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

Apache Arrow is a columnar in-memory analytics layer designed to accelerate big data. It houses a set of canonical in-memory representations of flat and hierarchical data along with multiple language-bindings for structure manipulation. It also provides IPC and common algorithm implementations.

QDBM is a library of routines for managing a database. The database is a simple data file containing key-value pairs. Every key and value is serial bytes with variable length. Binary data as well as character strings can be used as a key or a value. There is no concept of data tables or data types. Records are organized in a hash table or B+ tree.

This package adds the support of pgvector vectors to Tortoise-ORM as a new type of fields, it helps to filter/order by cosine similarity distances for scementic search using embeddings.

This package provides a Postgres SQL parser as a library.

This package provides Guile bindings to the WiredTiger ``NoSQL'' database.

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 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.

Prisma Client Python is an auto-generated and fully type-safe database client.

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).

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

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.

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.

The goal for nanodbc is to make developers happy by providing a simpler and less verbose API for working with ODBC. Common tasks should be easy, requiring concise and simple code.

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.

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.
