Cursors

Cursors in databases are tools that allow software to navigate through rows of data one at a time. Think of them like a pointer or marker that moves through a list, enabling the application to access, process, or update specific records individually. This is useful when performing operations that require row-by-row handling, especially with large datasets, by controlling the flow and keeping track of the current position in the data. Cursors help manage data efficiently in situations where set-based operations are not suitable.
