RE: forms

Hello Jason,

Hope you enjoyed your Microsoft Access course with BEST Training.
Thank you for your question regarding Subforms.

A subform is a form that is inserted in another form. The primary form is called the main form (main form: A form that contains one or more subforms.), and the form within the form is called the subform. A form/subform combination is often referred to as a hierarchical form, a master/detail form, or a parent/child form.

Subforms are especially effective when you want to show data from tables or queries (query: A question about the data stored in your tables, or a request to perform an action on the data. A query can bring together data from multiple tables to serve as the source of data for a form, report, or data access page.) with a one-to-many relationship (one-to-many relationship: An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of many records in the related table.). For example, you could create a form with a subform to show data from a Categories table and a Products table. The data in the Categories table is the "one" side of the relationship. The data in the Products table is the "many" side of the relationship
