better-sqlite3
The fastest and simplest library for SQLite3 in Node.js
The fastest and simplest library for SQLite3 in Node.js. Full transaction support. High performance, efficiency, and safety. Easy-to-use synchronous API (better concurrency than an asynchronous API... yes, you read that correctly). Support for user-defined functions, aggregates, virtual tables, and extensions. 64-bit integers (invisible until you need them). Worker thread support (for large/slow queries). Help this project stay strong! better-sqlite3 is used by thousands of developers and engineers on a daily basis. Long nights and weekends were spent keeping this project strong and dependable, with no ask for compensation or funding, until now. In most cases, if you're attempting something that cannot be reasonably accomplished with better-sqlite3, it probably cannot be reasonably accomplished with SQLite3 in general. -

RocksDB
A library with an embeddable, persistent key-value store for storage
RocksDB uses a log structured database engine, written entirely in C++, for maximum performance. Keys and values are just arbitrarily-sized byte streams. RocksDB is optimized for fast, low latency storage such as flash drives and high-speed disk drives. RocksDB exploits the full potential of high read/write rates offered by flash or RAM. RocksDB is adaptable to different workloads. From database storage engines such as MyRocks to application data caching to embedded workloads, RocksDB can be used for a variety of data needs. RocksDB provides basic operations such as opening and closing a database, reading and writing to more advanced operations such as merging and compaction filters. -

Testcontainers node
Supports tests, providing lightweight, throwaway instances of database
Testcontainers is an open source library for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container. No more need for mocks or complicated environment configurations. Define your test dependencies as code, then simply run your tests and containers will be created and then deleted. With support for many languages and testing frameworks, all you need is Docker. Use a containerized instance of your database to test your data access layer code for complete compatibility, without requiring a complex setup on developer machines. Trust that your tests will always start with a known state. Use containerized web browsers, compatible with Selenium, to run automated UI tests. Each test gets a fresh, clean instance of the browser, without having to worry about variations in plugins or required updates. -

Slick database
Slick (Scala Language Integrated Connection Kit) is a modern database
Slick is a modern database query and access library for Scala. It allows you to work with stored data almost as if you were using Scala collections while at the same time giving you full control over when a database access happens and which data is transferred. You can write your database queries in Scala instead of SQL, thus profiting from the static checking, compile-time safety and compositionality of Scala. Slick features an extensible query compiler which can generate code for different backends. It allows you to work with relational databases almost as if you were using Scala collections, while at the same time giving you full control over when a database access happens and what data is transferred. By writing your queries in Scala you can benefit from the static type checking, compile-time safety, and compositionality of Scala, while retaining the ability to drop down to raw SQL where needed for custom or advanced database features. -
Run applications fast and securely in a fully managed environmentRun frontend and backend services, batch jobs, deploy websites and applications, and queue processing workloads without the need to manage infrastructure.

goqu
SQL builder and query library for golang
SQL builder and query library for golang. goqu is an expressive SQL builder and executor. Query builder, parameter interpolation (e.g SELECT * FROM "items" WHERE "id" = ? -> SELECT * FROM "items" WHERE "id" = 1). Built from the ground up with multiple dialects in mind. Insert, multi insert, update, and delete support. Scanning of rows to struct[s] or primitive value[s]. While goqu may support the scanning of rows into structs it is not intended to be used as an ORM if you are looking for common ORM features like associations, or hooks I would recommend looking at some of the great ORM libraries. The test suite requires a postgres, mysql and sqlserver databases. -

migrate
Database migrations, CLI and Golang library
Database migrations are written in Go. Use as CLI or import as a library. Migrate reads migrations from sources and applies them in correct order to a database. Drivers are "dumb", migrate glues everything together and makes sure the logic is bulletproof. (Keeps the drivers lightweight, too.) Database drivers don't assume things or try to correct user input. When in doubt, fail. Package migrate reads migrations from sources and runs them against databases. Sources are defined by the `source.Driver` and databases by the `database.Driver` interface. The driver interfaces are kept "dump", all migration logic is kept in this package. -

Skunk
A data access library for Scala + Postgres
Skunk is a Postgres library for Scala. Skunk is powered by cats, cats-effect, scodec, and fs2. Skunk is purely functional, non-blocking, and provides a tagless-final API. Skunk gives very good error messages. Skunk embraces the Scala Code of Conduct. Skunk is pre-release software! Code and documentation are under active development! Skunk is published for Scala 2.12/2.13/3.1 and can be included in your project.Query and Command types are usually inferrable, but specifying a type ensures that the chosen encoders and decoders are consistent with the expected input and output Scala types. Postgres provides a protocol for execution of simple queries, returning all rows at once (Skunk returns them as a list). -

Sormula
Java ORM
Simple (Easy) Object Relational Mapping for Java Sormula is a Java library that moves data between Java objects and relational database tables. * Easy to Use * Simple to Understand * Minimal Configuration * Portable It provides select, insert, update, and delete, and many other common operations. One-to-one and one-to-many cascading for unlimited levels. Simplified IN operator parameter as java.util.Collection. Custom conversions between any Java class/type and column type. * Works with any relational database. Tested with H2, HSQLDB, Derby, SQLiteJDBC, MySQL, MariaDB, Firebird, DB2, Oracle 11g, PostgreSQL. * Performs as fast as plain JDBC. Performs faster than plain JDBC when caching is enabled. * Zero-configuration, zero-annotation use is possible. * Active record pattern may be used but is not required.

EJDB
Embeddable JSON Database engine C library
EJDB 2.0, Embeddable JSON Database engine C library. Simple XPath like query language (JQL). Websockets / Android / iOS / React Native / Flutter / Java / Dart / Node.js bindings. Docker image. Array elements are matched from start to end. In equal arrays all values at the same index should be equal. Lexicographically sort object keys in both maps. Do matching keys and its values starting from the lowest key. Database index can be build for any JSON field path containing values of number or string type. All documents in collection are sorted by their primary key in descending order. So if you use auto generated keys (ejdb_put_new) you may be sure what documents fetched as result of full scan query will be ordered according to the time of insertion in descendant order, unless you don't use query sorting, indexes or inverse keyword. -

cde4php - Cross Database Engine for PHP
Uniform Database Abstraction for PHP Development
Debby has replaced CDE in the Tina4Stack, you may want to check it out at http://tina4.com CDE is a PHP class which implements the general database functions in PHP and provides a common SQL platform for php development where developers change their databases but not their code. Supports Firebird, MySQL,Oracle,SQLite, MSSQL(both drivers),CUBRID,ODBC. CDE now supports date uniformity, param passing & BLOB handling across all the databases supported. CDE is not a replacement for PDO, in fact we may implement PDO in CDE to standardize PDO results and calls. Some PDO drivers are still regarded as EXPERIMENTAL on PHP website, so use with caution. Feel free to suggest any features you wish to be added or submit a bug report with the tracker -
