Overview of methods for integrating data mining into DBMS

Data Mining is aimed to discovering understandable knowledge from data, which can be used for decision-making in various fields of human activity. The Big Data phenomenon is a characteristic feature of the modern information society. The processes of cleaning and structuring Big data lead to the formation of very large databases and data warehouses. Despite the emergence of a large number of NoSQL DBMSs, the main database management tool is still relational DBMS. Integration of Data Mining into relational DBMS is one of the promising directions of development of relational databases. Integration allows both to avoid the overhead of exporting the analyzed data from the repository and importing the analysis results back to the repository, as well as using system services embedded in the DBMS architecture for data analysis. The paper provides an overview of methods and approaches to solving the problem of integrating data mining in a DBMS. A classification of approaches to solving the problem of integrating data mining in a DBMS is given. The SQL database language extensions to provide syntactic support for data mining in a DBMS are introduced. Examples of the implementation of data mining algorithms for SQL and data analysis systems in relational databases are considered.
