A cursor is a mechanism used to iterate over the elements of a collection, such as a database result set or a data structure. It allows you to access and manipulate individual elements one at a time. Cursors are commonly used in database management systems and graphical user interfaces. There are several types of cursors available, depending on the specific programming language or database system being used. Here are some common types of cursors:

Forward-only Cursor

Scrollable Cursor

Static Cursor

Dynamic Cursor

Keyset-driven Cursor

Read-only Cursor

These are some of the commonly used cursor types. The availability and specific characteristics of cursor types may vary depending on the programming language, database system, or framework you are working with.
