This one is a special type of data source, which is not connected to the service of the cloud but local to the app. This is generally used as the local to the device and cannot be shared among devices for one or multiple users. Also, they can be saved as well as retrieved locally. To operate collections, Clear function, ClearCollect, and Collect can be used.

An environment is referred to as the space to keep, manage and share the data, apps, and flow of the business.
