The data loading strategy mentioned in this paper is the OLTP system as the source system, and
The general data loading strategy used by ETL data to be loaded into OLAP system.
Depending on the specific nature of this approach, the ETL data load generally has the following four kinds of parties

1. Time Stamp mode
You need to uniformly add time fields as timestamps in the business tables in the OLTP system (such as the time fields already availab
A multidimensional database (Multi dimesional DATABASE,MDD) can be simply understood as storing data in an n-dimensional array, rather than storing it as a record as a relational database. So it has a lot of sparse matrices, and people can look at the data through multidimensional views. Multidimensional database adds a time dimension, compared with relational database, its advantage is that it can improve data processing speed, speed up reaction time and improve query efficiency.
