VTWM: An Incremental Data Extraction Model Based on Variable Time-Windows
2020
EAI Endorsed Transactions on Collaborative Computing
Continuously extracting and integrating changing data from various heterogeneous systems based on an appropriate data extraction model is the key to data sharing and integration and also the key to building an incremental data warehouse for data analysis. The traditional data capture method based on timestamp changes is plagued with anomalies in the data extraction process, which leads to data extraction failure and affects the efficiency of data extraction. To address the above problems, this
