Reusable Components for the Web
The visualisation is a very specific part of the User Interface that is powered by D3. A versatile dedicated chart engine has been built on top of it, with an optional integration with React.
SDMXSource and Tools
The Community works in close partnership with Eurostat enabling the reuse of open source and common modules from the SDMX Reference Infrastructure (RI) package. This includes a web service supporting information exchanges with other modules, and consumption of internal and external flows in sdmx-ml, sdmx-json, and sdmx-csv formats, a web interface to support mappings between different data structures, and a storage for sdmx structural artefacts.
SDMX-RI and SDMXSource are released under open source licenses, and used within more than 50 countries worldwide. It is available in both Java and .NET and can be used with different database engine back-ends such as Mariadb, MSSQLServer, and Oracle.
An out-the-box and exchangeable search engine, Solr (Apache Lucene), provides storage for search documents and returning of a relevant subset by search queries. Storage of accumulated data for dynamic facet generation as well as non-search related information such as configuration settings.
Solr is an enterprise open source search engine, written in Java, that uses a NoSQL database to enable extended search capabilities.
The .Stat Suite is able to run on the free version of Microsoft SQL Server, SQL Express, although performance is good, even at reasonable volumes of data, if usage is high and data is voluminous then it is advisable to run on the licenced versions of Microsoft SQL Server.
As the front-end user applications are built on the RCW (React) they are database agnostic, and can just as easily run of the SDMX-RI Java package and Oracle database engine.
The .Stat Suite being based on a SOA, will in the future move towards a complete database agnostic solution.
You can find a complete list of the technologies used in the .Stat Suite project on our detailed documentation pages.
