Data Modeler

Data modeler is a module that lets end users create a data hierarchy such that it will be stored in the system and can be used in the application. This data can be business related as well as for intermediate calculations. User can create the following:

1. Entity (Business Object)
2. Data Model (Business Model)
3. Enumeration (LOVs) – For LOV elements (Radio Button, Checkbox, LOV Slider, Dropdowns)

Entity

An Entity is a collection of information defined as a single unit. A user can create multiple entities which he/she would like to use in an application. These entities can be as small as a page or complex for an entire journey.

There are two types of user defined entities that are created for an application on Vahana Cloud.

1. Business Entity (Entity Store) : Business Entity is the core of any application, and all structure of all business-related data will be defined here.
2. Temporary Entity (Temp Store) : Temporary Entity as the name suggests is used for intermediate calculations and it only persists till the session lasts. These parameters will be used in tasks and events only in vDesigner.
