To speed ORDER BY dba_date DESC (and optionally WHERE/filter), create an index. Note: B-tree indexes are order-agnostic—same index used for ASC or DESC—except with some DBs supporting DESC ordering in index definition.
(Requires careful planning and has limitations.)
Running a query sorted by a date field in descending order can become incredibly slow on massive tables with millions of rows. When a database has to sort data without preparation, it performs a costly "Sort Operator" in memory. new dba date desc

When you insert data, the database automatically adds the current time. Running ORDER BY created_at DESC will immediately show your new record at the top.
When auditing a SQL Server instance, you may need to find the most recently created database. SQL Server tracks this metadata in the sys.databases system catalog view.
