What Does Cursor Mean?

A database cursor is an object used to pinpoint records in a database. Just like a typing cursor is used to alert you where your text will appear, a database cursor also shows you the specific record in a database that is being worked upon.

Techopedia Explains Cursor

When a database file is opened, the cursor points to the first record in the file, and using various commands the cursor can move to any location within the file.

When designing a database, the developer must take care not to use too many open cursors. Each cursor uses a (admittedly small) amount of memory. However, if cursors are never closed, that is, discarded after completing their work, they can pile up in memory and cause performance problems.
