Managing Large Scale Unstructured Data with RDBMS

With the rapid development of information technology, the needs of unstructured data storage and processing is growing rapidly, which develops a new requirement for the database storage. Traditional row-oriented relational databases appear to be inadequate for the data query and analysis. In this paper, we propose a novel approach to store the unstructured data in a relational database. By splitting the VALUE property of the unstructured KEY/VALUE data and recreating the two-dimensional data, the original data can be stored in relational databases. The system introduced in this paper is designed to handle this task. In addition, this system rebuilds the SQL as its query language, which makes it compatible with relational databases. In experiments of the query for unstructured data, the outcomes show that the system is good at decomposing the SQL statement submitted by users, and generating the corrected sub-query statements. The results of the experiments show that the performance of this system is good.
