Définition de l'open data / différence avec la big data | Réussir son CRM

From Google Translate: "Aside from the fact that we talk about data in both cases, there is no real correlation or similarity between the two concepts. The Big Data concerns the methods of collecting and processing a large volume of data, in real time, and of great richness.

Open data is a way of accessing information. You can be a big consumer of open data without having the problems of Big Data. It all depends on how you consume open data: if you access real-time open databases that you display on your websites or an intranet without storing them (such as Google Maps points of interest For example), the big data does not concern you.

On the other hand, if you prefer to retrieve the information in your information system, to enrich it or to reprocess it before disseminating it, your use of open data may need to be expert in big data . It all depends on how much data you get, and how often."
