What is defined as a collection of files describing the objects, connections, and user interface elements in Looker?

The term that represents a collection of files describing the objects, connections, and user interface elements in Looker is referred to as a project. In Looker, a project serves as a development space where developers can create, manage, and organize LookML files. These LookML files define the structure of how data is modeled, including the relationships between different data sources and the visual elements that users interact with in the Looker interface.

Projects allow for a modular and organized approach to building LookML, making it easier for teams to collaborate and maintain their data models. By housing all the necessary files within a project, Looker ensures that everything related to development is kept in one place, which is essential for version control and code management.

The other options do not accurately capture this concept. A repository typically refers to a storage space for code and files, but it doesn’t specifically denote the LookML elements in Looker. A workspace refers to the area within Looker where users can interact with data and visualizations, but it doesn't represent the collection of LookML files. A database is the backend storage system that houses the actual data but is not related to the organizational structure of LookML files within Looker.
