Research and realizations of integrated methods of seismic disaster prevention data

摘要

With the development of information technology, we set up a large amount of seismic disaster prevention data in the field. Because of the heterogeneity of seismic disaster prevention data, it makes difficult for data to be exchanged and shared. To solve this problem, we use an optimization of heterogeneous data integration solution based on ETL technology. By using the ETL integrated optimization model, we realize the efficient integration of heterogeneous data. Experiment proved that quickly and effectively, the solution can eliminate the heterogeneity of the data and ensure consistency and accuracy of data. When integrating massive data, it performs better efficiency and has a good application value.
