Goryachkin Boris Sergeevich, Alekseev Andrey Sergeevich

Problem statement. To store different types of data, different databases are used, operations to which are performed at different speeds. It is necessary to optimize the execution time of user queries to different databases. Goal. To increase the efficiency of user interaction with different types of databases. Results. The time of operations for changing and deleting data from different types of databases is considered, depending on the amount of data, as well as the type of data. Practical significance. The data was obtained and recommendations for the use of databases were developed based on them, depending on their number and types. This will allow you to select the most efficient databases and distribute data across them on a case-by-case basis.

Keywords:Lots of databases, PostgreSQL, Cassandra, MongoDB, Neo4j.
