Explain the following in your own words:1) System Log2) Transaction support in SQL

A System Log is essentially a file that records all the significant events related to system activities. It's like a diary for your computer where it notes down what applications have been used, any changes in system configuration, any system errors, and so on. It's a very useful tool for troubleshooting issues as it provides a timeline of events leading up to a problem.

Transaction support in SQL refers to a set of operations that are performed as a single unit. It's like a package deal - either all operations are successfully executed or none of them are. This is crucial in maintaining the integrity of the database. For example, if you're transferring money from one bank account to another, the transaction would involve deducting the amount from one account and adding it to the other. If either operation fails, the entire transaction should be rolled back to avoid any discrepancies.
