What is a Form?

Every useful web application depends on user entered data. For example, an article will consist of a title, a summary and a body. We structure data using forms. Once you have such structure, then it is easier to create other pages such as article listings and article display pages. Forms are used to shape user entries. You can put limits on how and what a user can enter. If you use a dropdown, users have to select one of the options. If you add a numeric validation, then they can only enter numbers.

A form is a kernel for an application. Since everything else will depend on user entered data, forms are basically definitions for your applications. They create the structure for the database. If you have have experience with database design, Memberkit forms are basically conventional database tables.

An application may contain many forms. They can work independently or they can be connected to each other. To connect data in multiple forms, you can use a feature called "Relations". An example to relations would be pictures and album forms on a Picture Album application. A picture can have category field and an album can have a name field. If we connect "album name" to "picture category", users can assign a picture into an album when they upload a new picture.
