MS server used transact SQL whereas Oracle makes use of PL/SQL Procedural Language and a Structured Query Language. All the changes are made in memory and nothing is actually done explicitly unless an external COMMIT command is not used. The provision of grouping procedures together into packages is something that is not available with MS SQL Server. The main difference between the two languages is how they handle variables, stored procedures, and built-in functions. On the other hand, SQL is supported by Windows and Linux.
