Arenadata DB (ADB) is a distributed analytical database built on Open Source massively parallel Greenplum DBMS, designed to store and process large data volumes (up to tens of petabytes). ADB is the ideal tool for enterprise data warehousing (EDW), business intelligence, ad-hoc queries, and enterprise-grade data science. ADB is the most effective for: 1) complex inquiries that involve the processing of huge data volumes and sophisticated analytical functions (including user behavior analytics); 2) any types of reports (operating, management, regulatory); 3) ad-hoc in-depth analysis; 4) effective joining of large data tables; 5) marketing campaign and loyalty systems; 6) different types of scoring; 7) predictive analytics (demand, stock).
