Software Development Kit

Open source conceptual resources to develop distributed, scalable, multi tenant web application in N-Tier architecture. Front tier with single code base hybrid web assembly, android, windows clients. Application tier with application server. Service tier with administration server and operational data services. Data tier with database stores (available: npgsql, mysql, mariadb, sqlserver, oracle, mongo, sqlite, cosmodb, azuresql, inmemorydb) and blob/file storages.

Benchamrks performed and specialized for Undersoft SDK usage and purpose and for them results show that Undersoft SDK is ~ 5 times faster with ~ 5 times less RAM usage then .NET Standard Collections and Parallel Math operations on IEnumerables
