A database dump contains a record of the table structure and/or the data from a database and is usually in the form of a list of SQL statements ("SQL dump"). A database dump is most often used for backing up a database so that its contents can be restored in the event of data loss. Corrupted databases can often be recovered by analysis of the dump.
The characteristics of the database itself are taken into consideration when attempting preservation of said database. Relational databases are made up of tables which contain data in records and these tables then connect to one another through common data points that are stored in their records. [3]

[1] For example, database replication is used to keep multiple copies of data synchronized with database servers that store data in different locations.
Presto (including PrestoDB, and PrestoSQL which was re-branded to Trino) is a distributed query engine for big data using the SQL query language. Its architecture allows users to query data sources such as Hadoop, Cassandra, Kafka, AWS S3, Alluxio, MySQL, MongoDB and Teradata, [1] and allows use of multiple data sources within a query.
