High Level Architecture Low Level Design Currently MySQL supports EXPLAIN SELECT, but it doesn't support EXPLAIN for INSERT, REPLACE, UPDATE and DELETE. An execution plan for the complex (and probably multi-table) INSERT/REPLACE/UPDATE/DELETE may not coincide with a plan of respective SELECT quer...

What is multicore architecture? What does spooling mean? How to do loop termination by user query? Describe a Forever loop in Scratch, give an example of a situation where you might use it, and explain why you would use a Forever loop rather than another looping structure. ...
Oracle 12c introduced multitenant architecture, and bigfile tablespaces work well in a pluggable database (PDB) context. The flexibility of bigfile tablespaces fits the cloud environments, as storage needs in the cloud often involve dynamically scalable infrastructure. With the use of bigfile tablespaces...
