  - In the context of database, a form is a window or screen which contains numerous fields, or spaces to enter data.
  
  - For any user who views the form gets an idea of its contents as each field holds a field label.
  
  - Using a form is more easy than generating queries to create tables and insert data into fields.
  
  - Databases like SQL and Oracle do not use built-in forms, employing the query option for data creation and manipulation instead.
  
  - For handling these databases it is essential to have querying knowledge.
  
  - For easy form access and manipulation the fields and field labels are organized in a logical manner.
  
  - While making an entry into fields of a form, it is important to be careful about the field types, which are generally set when the form is created.
  
  - An attempt to enter values that do not satisfy the field constraints will fail.
  
  - For instance, a field with a field type "not null" does not take null values and cannot be left blank.
  
  - Some fields may also have table relationships connected by using a foreign key; any alteration done to such a field in a form will need special care.
  
  - Some online databases also have built-in form templates included in them.
  
  - These databases can easily be used by users who are not even aware of scripting, as all entries and changes can be made in the form by a single click.
