Understand schema builder

A schema builder provides you with an illustration of the logical structure of your application's database. The forms in your application come with the facility of interacting with each other by way of relationships. The term relationship refers to the link that is created while using a lookup or a subform field to enable one form to access the data stored in another form. Your application can have many forms with many relationships. Schema builder presents a holistic view of the forms and relationships between the related forms is a pictorial manner.

The illustration in the image represents your application in terms of forms and the existing relationships. The circles denote forms and the lines denote relationships. Each form along with its fields and reports is referred to as an entity.

Attributes of the schema builder:

Let's assume that you have an Order Management application with forms like Product Details, Stock Details, Order Details, Vendor Information, Product Catalogue, and many more. In schema builder, all these forms are portrayed graphically along with their relationships. If you click on the circle that is assigned for Product Details, the fields in the form and the reports associated with the form are displayed is their respective tabs. The fields and the enabled field properties will be available. If you need to make changes, click the edit icon to directly navigate to the form builder directly.

You can create a new relationship in schema builder. Point and drag from one form to another, select the fields in the respective forms, select the display options, and complete the procedure. Let us say you need to create a relationship between Order Details and Stock Details. You need to lookup the field Status in Stock Details from Order Details. Point the cursor on Stock Details and drag it towards Order details. The Relationship window allow appear for you to create the required relationship.

To create a new relationship:

  1. Click Settings. The ApplicationSettings page will appear.
  2. Click Schema Builder under Developer Tools. The illustration will appear.
