+# USE
+Starting from [Timeplus Enterprise 2.6](/enterprise-v2.6), you can create a database to organize Timeplus streams, materialized views, or connect to other systems such as MySQL and Iceberg without creating multiple external tables repeating the connection information.

+```sql
+USE my_database;
