Similar to the database, except that the database focuses on some transactional operations, such as modify, delete, query, in the database this piece occurs more. The Data Warehouse is primarily focused on querying. For the same amount of data in the database query is relatively slow, in the Data Warehouse query efficiency is relatively fast. The Data warehouse is query-oriented, and the amount of data processed

Hive supports storing metadata in relational databases, such as MySQL and Oracle;
In this case, the hive metadata is stored in MySQL.
In the previous articleArticleI listed a simple hive operation instance, created a table test, and loaded data to this table. These operations are similar to relational database operations, we often compare hive with relational databases because many knowledge points of hive are similar to those of relational databases.
Relational databases also contain tables,
