Evita is a specialized database with easy-to-use API for e-commerce systems. Purpose of this research is creating fast and scalable engine that handles all complex tasks that e-commerce systems has to deal with on daily basis. Evita should operate as a fast secondary lookup / search index used by application frontends. We aim for order of magnitude better latency (10x faster or better) for common e-commerce tasks than other solutions based on SQL or NoSQL databases on the same hardware specification. Evita should not be used for storing and handling primary data, and we don't aim for ACID properties nor data corruption guarantees. Evita "index" must be treated as something that could be dropped any time and built up from scratch easily again.

Apache Empire-db is an Open Source relational data persistence component which allows database vendor independent dynamic query definition as well as safe and simple data retrieval and updating. Compared to most other solutions like e.g. Hibernate, TopLink, iBATIS or JPA implementations, Empire-db takes a considerably different approach, with a special focus on compile-time safety, reduced redundancies and improved developer productivity.

The chart-fx charting library is an extension in the spirit of Oracle's XYChart and performance/time-proven JDataViewer charting functionalities. Emphasis was put on plotting performance for both large number of data points and real-time displays, as well as scientific accuracies leading to error bar/surface plots, and other scientific plotting features (parameter measurements, fitting, multiple axes, zoom, ...). The library also contains a small set of math routines that can operate directly on the DataSet primitive for fitting, computing spectra, linear algebra, FIR/IIR filtering, and other functionalities common to signal processing.
