Statistisk sentralbyrå - SSB
Project Overview
Statistics Norway (SSB) is the central institution for official statistics in Norway, responsible for collecting and analyzing data across various sectors to provide insights that influence government policy and decision-making. SSB's legacy systems, built using Java, were becoming increasingly difficult to maintain and scale, especially with growing data demands.
Xala Technologies was tasked with modernizing SSB's legacy Java applications by migrating them to the .NET Core framework. The primary objective was to ensure that the new systems could handle large volumes of statistical data efficiently, improve performance, and integrate seamlessly with SSB’s data processing and analysis workflows.
