The STSdb W4.0 engine is based on the WaterfallTree™ data structure – a patented STS Soft SC technology. W-tree effectively solves one of the most fundamental problems in the database world - speed degradation on random keys indexing.
This allows STSdb W4.0 to support multiple indexes in real-time over multiple tables without impacting performance. The database works extremely fast with both random and sequential keys.

STSdb is an open-source, client/server and embedded NoSQL database and virtual file system in one. It is built up from scratch without using any third party components. Data is stored in a very flexible key-value format where the key consists of the combination of sub-keys and an associated value.
The innovative design makes STSdb perfect for BigData and cloud applications.
In STSdb data is multi-dimensionally indexed (lexicographically ordered) by key. This characteristic allows it to support existing data models and different indexing strategies.
The backbone of STSdb is WaterfallTree™ - patent pending technology of STS Soft SC. Formally W-tree is a natural generalization of B+-tree. In general operations in B+-tree are executed synchronously (one by one) while in W-tree operations are executed аsynchronously (in groups). As a result W-tree solves the problem of speed degradation when indexing records with random keys. This allows to maintain multiple indexes in real-time without harming system performance. Theoretical models and empirical studies show 100x increase in speed of indexing using W-tree instead of B+-tree.
