You will notice a slow loading 'bound' form for larger volumes of data sets which is an overhead that could be easily avoided if adopting the unbound approach. The coding for this type of form is not too exhaustive but does require some basic knowledge which is taught to the more advanced delegate (normally day 4 or 5). Personally, using unbound Access database forms is a more professional and polished approach as it mimics the way a 'true' database system should be operated as well as giving you full control and still maintain data integrity.
No matter what type of application form you need you are likely to find that the best place to find what you are looking for is using the Internet. Here you will find a number of different sites where you can find a template for an application form. You need to know what type of form you are looking for before you start out, this will make it much easier for you to narrow your search instead of having to wade through thousands of different templates to find the one you are looking for.
