The invention discloses an
acquisition protocol multi-version application method and
system, and relates to the technical field of
big data acquisition, and the method comprises the steps: adding a version number identifier to an
acquisition protocol and each field in the
acquisition protocol; the collection SDK compares the version number of the collected data with the collection protocol
metadata, marks a corresponding version number on a corresponding field and reports the version number; the cloud side correspondingly stores the field version numbers into a wide
table database according to the field version numbers; and the
application layer selects available version number
field data as required. When an acquisition protocol is created or updated, all fields are numbered by independent versions, the versions are controlled to be fine-grained, and
field data corresponding to the version numbers can be freely selected when using data is applied; unified
processing is carried out according to the field version number during cloud cleaning and warehousing, iterative development does not need to be carried out on an old version cleaning and warehousing process, and manpower is saved; in the storage stage, other fields which are not modified and updated in the same protocol do not need to be additionally and repeatedly stored due to consideration of old version
data value, so that the storage space is greatly saved.
