I found very interesting the initiative of the European Central Bank, to provide a statistical service on-line in the so-called Statistical Data Warehouse (SDW).
This Data Warehouse is aimed at a broad spectrum of users (financial analysts, journalists, businesses, economists, researchers, etc. ..). Provides macroeconomic data on-line in the euro zone: inflation, exchange rates, labor costs, unemployment, productivity, public deficit, public debt, payments balance, international investment position, sociodemographic data, tax information, etc...
The accessibility, presentation and navigation are very intuitive, allowing data downloads in multiple formats. Given the volume of information has a powerful search engine. Provides multiple predefined reports, indicators, ratios, rates of change, facilitates comparisons, advanced filters, time series study, deep historical and excellent response times. Also, there are different levels of aggregation and ranking system that facilitates detailed navigation. The update is in real-time from statistics tables from publications of the ECB.An excellent online tool for obtaining euro area statistics: https://sdw.ecb.europa.eu/
