LiteDB is a serverless database delivered in a single small DLL (< 450kb) fully written in .NET C# managed code (compatible with .NET 4.5 and NETStandard 2.0). Install it via NuGet or just copy the DLL to your bin project folder. LiteDB is a simple and fast NoSQL database solution. Ideal for mobile apps (Xamarin ready), desktop/local applications, application file format, web applications, and one database per account/user data store. Portable UWP and Xamarin iOS/Android, ACID transactions, single datafile (like SQLite), recovery data in writing failure (WAL mode), map your POCO class to BsonDocument, fluent API for custom mapping. Cross collections references (DbRef), store files and stream data (like GridFS in MongoDB), LINQ query support, free for everyone, including commercial use. LiteDB supports SQL-like language for data and structure manipulations. You can insert, update, delete or query your database using a very similar SQL relational language.

This project consists out of a windows based designer application and a library (that can run on multiple platforms, including android) together with several demo applications (including an MVC3 chatbot client and an android application). It is probably best compared to a database management system, but for neural networks instead of relational data. As such, the library is optimized for handling any type of data-size by using advanced streaming and caching algorithms. With the designer, you are able to create different types of decision trees, random forests, n-grams, pattern-matchers, conversational agents and all sorts of AI related algorithms. You can combine statistical approaches as well as pattern matchers or others. Do natural language processing, image or data analysis & interpretation,...

BearDB is a database provider for modern web applications and javascript frameworks. BearDB is our Relational Database System which runs on most platforms and supports multiple programming languages. A REST server allows web applications to go directly to the database. BigBear is our Large Scale Database System which supports SQL. BigBear is similar to modern distributed NoSQL database systems, with the addition of support for SQL and a REST server.

- Suitable for engineering, ERP, research tasks. - Can be easily used as a local database in C# application. - Can be run as "listening" service on a local machine or a server. - Nested data structures supported. - PowerShell interface. See project Wiki for more.
