The invention provides a hierarchical storage method for multi-
source data, a storage medium, a program product and
electronic equipment, and the method comprises the steps: obtaining the multi-
source data of a service, and converting the format of the multi-
source data into a column storage format; performing embedded space pre-regularization
processing on the multi-source data after format conversion to construct an n-dimensional simplex geometric constraint space of the multi-source data, and according to the n-dimensional simplex geometric constraint space, generating a multi-layer composite
label, at least comprising a business semantic
label and a cold and hot aging
label, of the multi-source data; dividing the multi-source data into hot data, temperature data and cold data according to the cold and hot aging labels; the hot data, the temperature data and the cold data are stored in different storage
layers respectively; and obtaining a
data query request, and routing the
data query request to one of the three storage
layers according to the service semantic tag. The problems of semantic
confusion, low
storage efficiency and low access efficiency of
bank data lakes in multi-source heterogeneous data fusion in the prior art are solved.
