DataKit
Connect processes into powerful data pipelines
Connect processes into powerful data pipelines with a simple git-like filesystem interface. DataKit is a tool to orchestrate applications using a Git-like dataflow. It revisits the UNIX pipeline concept, with a modern twist: streams of tree-structured data instead of raw text. DataKit allows you to define complex build pipelines over version-controlled data. DataKit is currently used as the coordination layer for HyperKit, the hypervisor component of Docker for Mac and Windows, and for the DataKitCI continuous integration system. src contains the main DataKit service. This is a Git-like database to which other services can connect. ci contains DataKitCI, a continuous integration system that uses DataKit to monitor repositories and store build results. The easiest way to use DataKit is to start both the server and the client in containers. -

DataScript
Immutable database and Datalog query engine for Clojure, ClojureScript
An immutable in-memory database and Datalog query engine in Clojure and ClojureScript. DataScript is meant to run inside the browser. It is cheap to create, quick to query and ephemeral. You create a database on page load, put some data in it, track changes, do queries and forget about it when the user closes the page. DataScript databases are immutable and based on persistent data structures. In fact, they’re more like data structures than databases (think Hashmap). Unlike querying a real SQL DB, when you query DataScript, it all comes down to a Hashmap lookup. Or series of lookups. Or array iteration. There’s no particular overhead to it. You put a little data in it, it’s fast. You put in a lot of data, well, at least it has indexes. That should do better than you filtering an array by hand anyway. The thing is really lightweight. The intention with DataScript is to be a basic building block in client-side applications that needs to track a lot of state during their lifetime. -

EliasDB
EliasDB a graph-based database
EliasDB is a graph-based database that aims to provide a lightweight solution for projects which want to store their data as a graph. Build on top of a custom key-value store that supports transactions and memory-only storage. Data is stored in nodes (key-value objects) which are connected via edges. Stored graphs can be separated via partitions. Stored graphs support cascading deletions - delete one node and all its "children". All stored data is indexed and can be quickly searched via a full text phrase search. EliasDB has a GraphQL interface which can be used to store and retrieve data. For more complex queries EliasDB has an own query language called EQL with an sql-like syntax. Includes a scripting interpreter to define alternative actions for database operations or writing backend logic. Written in Go from scratch. Only uses gorilla/websocket to support websockets for GraphQL subscriptions. The database can be embedded or used as a standalone application. -

Finance Database
This is a database of 300.000+ symbols containing Equities, ETFs, etc.
As a private investor, the sheer amount of information that can be found on the internet is rather daunting. Trying to understand what type of companies or ETFs are available is incredibly challenging with there being millions of companies and derivatives available on the market. Sure, the most traded companies and ETFs can quickly be found simply because they are known to the public (for example, Microsoft, Tesla, S&P500 ETF or an All-World ETF). However, what else is out there is often unknown. This database tries to solve that. It features 300.000+ symbols containing Equities, ETFs, Funds, Indices, Currencies, Cryptocurrencies and Money Markets. It, therefore, allows you to obtain a broad overview of sectors, industries, types of investments and much more. The aim of this database is explicitly not to provide up-to-date fundamentals or stock data as those can be obtained with ease (with the help of this database) by using yfinance, FundamentalAnalysis or ThePassiveInvestor. -
21
FluentPDO
A PHP SQL query builder using PDO
FluentPDO is a PHP library that provides a fluent interface for building SQL queries using PHP’s PDO.

REST backend tests based on Pytest, integrated with Docker, so you can test the full API interaction, independent on the database. As it runs in Docker, it can build a new data store from scratch each time. -
23
GUN
Cybersecurity protocol for syncing decentralized graph data
GUN is a small, easy, and fast data sync and storage system that runs everywhere JavaScript does. The aim of GUN is to let you focus on the data that needs to be stored, loaded, and shared in your app without worrying about servers, network calls, databases, or tracking offline changes or concurrency conflicts. This lets you build cool apps fast. When a browser peer asks for data, it'll merge the reply with its own data using a CRDT, then cache the result. GUN is fully decentralized (peer-to-peer or multi-master), meaning that changes are not controlled by a centralized server. A server can be just another peer in the network, one that may have more reliable resources than a browser. You save data on one machine, and it will sync it to other peers without needing a complex consensus protocol. It just works. GUN can be used in both browsers and servers. We have made it easy to install in many different environments. -
24
Genji
Document-oriented, embedded SQL database
Genji is an embedded database written in Go that aims to simplify dealing with data in the modern world. It combines the power of SQL with the versatility of documents to provide a maximum of flexibility with no compromise. Run powerful queries on rich documents with an expressive SQL syntax. Create tables with strict schemas, partial schemas, or no schemas at all to control your data the way you want it. Fully serializable transactions, in-memory mode, memory usage control, and more. Genji was designed for simplicity in mind. It is really easy to insert and read documents of any shape. Genji mixes the best of both worlds by combining powerful SQL commands with JSON. Genji tables are schemaless, but it is possible to add constraints on any field to ensure the coherence of data within a table. -

GeoIP2 Reader for Go
Unofficial MaxMind GeoIP2 Reader for Go
This library reads MaxMind GeoLite2 and GeoIP2 databases. This library is built using the Go maxminddb reader. All data for the database record is decoded using this library. If you only need several fields, you may get superior performance by using maxminddb's Lookup directly with a result struct that only contains the required fields. (See example_test.go in the maxminddb repository for an example of this.) Metadata takes no arguments and returns a struct containing metadata about the MaxMind database in use by the Reader. Enterprise takes an IP address as a net.IP struct and returns an Enterprise struct and/or an error. This is intended to be used with the GeoIP2 Enterprise database.
