Precisions
The data access mechanisms can generate significant processing times and therefore a significant use of resources. Most often these loads are associated with a user session and therefore multiply with the increase in traffic on the service. DBMS engines offer several effective analysis mechanisms with regard to the organization of data and needs. Reducing the data access load for a user session is environmentally beneficial and efficient for the technical performance of the service.
