Study on Textual Data Sources based Real-Time ETL
This paper focuses on the issues of real time ETL based on the semi-structured textural data sources.Because the mapping between text data and relational database relies on object-orient programming language,the paper first implements a text-object-relation mapping model for textual data sources based real-time ETL,and then studies the characteristic of real-time and security of purposed model.The cache mechanism aims to solve the performance difference between object-text mapping and object-relation mapping,and furthermore both encryption and signature mechanism aim to guarantee the security of the data in cache.The theoretical analysis and experiments prove the high efficiency and practicality of the mapping model.
