A Critical Review of SQL-Based Mining Relational Database

Mining database aims to discover hidden, yet potentially useful knowledge in database and it has many applications. SQL-based mining relational database is one of its branches, which takes advantage of Standard Query Language to mine datasets. However, due to the little survey research emphasis on this very specific area, currently few literature review has been conducted to investigate, summarize or critique this field. In order to fill this existing gap, in this paper, an original critical review has been carried out, which is based on academic research papers since 1990. To author’s best knowledge, it is the first time to conduct such a review in a critical way regarding SQL-based mining relational database. This review highlights a strong point and a point of improvement and organized in a reversely chronologic order. The review result shows that since 1990, there have been some research work done to mine relational database by SQL. Almost all of it was empirical and some of it was based on the extension of the standard SQL, however all of research or proposed systems did not support distributed relational databases.
