salvataggio permanente(The saving of the state of a workflow instance or a service to a storage medium, so that it can be unloaded from memory or recovered after a system failure)
persistence The capacity of a substance to remain chemically stable. This is an important factor in estimating the environmental effects of substances discharged into the environment. Certain toxic substances (e.g., cyanides) have a low persistence, whereas other less immediately toxic substances (e.g., many organochlorines) have a high persistence and may therefore produce more serious effects[pə'sɪstəns]adj.
