Forms in Access allow users to view, add, edit, and display database data. There are two main types of forms: bound forms, which are connected to an underlying data source like a table or query, and unbound forms, which are not connected to a data source. Common bound form types include single item forms which display one record at a time, multiple item forms which show multiple records, and split forms which divide the form horizontally or vertically with one section showing a single record and the other displaying a list of multiple records. Forms can be created using the Form Wizard or other methods.
