What does the 'view' file in LookML primarily define?

The 'view' file in LookML primarily defines fields and calculations for a data table. When creating a view, you outline the dimensions and measures that can be used in queries. This includes specifying the attributes (which serve as dimensions) and the calculations (which serve as measures) that summarize the data. Through the view file, you can create database fields, define calculations, and determine how data should be represented visually in Looker.

By establishing these fields and calculations, the view file provides a structured way to interact with the underlying data, making it essential for creating meaningful analyses within Looker. It allows users to define how data should be presented and how different metrics or attributes are calculated, which is crucial for data exploration and reporting.
