DataThings is editor of GreyCat, a temporal-graph database implementation specifically designed to support management of relational data evolving in time and/or space. It is basically a combination of timeseries and relational database.GreyCat is made to offer the best performances on live data analytics and continuous machine learning, by also providing implementation of the most common learning algorithms able to work with data streams.DataThings team is specialised in software engineering and artificial intelligence, and can support various industries in their transition to Industry 4.0, with specific software developments, empowered by GreyCat.We help industries in banking, infrastructures management (national electricity distribution grid), manufacturing industries, smart water management, to organise complex data, prepare datasets, execute learning, evaluate accuracy and integrate in production.GreyCat provides an ideal platform to accelerate AI implementations by integrating in a unique solution, the data lake, the ETL, the data analytics and machine learning algorithms, the APIs for integration, and the native connectors to create web-based dashboards.

Software systems tend to acquire capabilities of adaptation, evolution and openness.These abilities require the execution environment to be highly flexible and dynamic, andrequire new tools to handle these abilities. In electronics, tools have been set up to copewith the huge heterogeneity and number of components, and the adaptation of existingproducts to new technologies. Openness of documentations and specifications in thisarea led to a wealth of solutions made by industrials or individuals fond of electronics.Inspired by electronics’ achievements this thesis contributes in improving the flexibilityof software systems while maintaining a high level of reliability. The contribution isthreefold. (1) A new component model, which improves flexibility to enable connectionof heterogeneous components. (2) Tools from model driven engineering, to create, edit,simulate and validate the structure and behavior of component assemblies prior to their(re-)deployment. (3) A runtime environment built on top of a service-based architectureto support evolutions, adaptations and openness required by the proposed componentmodel.This thesis has been validated on a use case from an Ambient Assisted Living project.In this domain, software systems have to be adaptive and flexible, to fit the needs andpathology evolutions of elderly people. Although there still is a long way to go, thebenefits gained from the use of this approach in this context proved the relevance ofthis thesis.
