LookML
LookML is a modeling language used in Looker, a business intelligence and data analytics platform, to define data relationships, metrics, and business logic in a SQL database. It allows developers to create reusable data models that abstract complex SQL queries, enabling non-technical users to explore data through a consistent and governed interface. LookML files are version-controlled and can be deployed to manage how data is presented and analyzed in Looker.
Developers should learn LookML when working with Looker to build scalable and maintainable data models that ensure data consistency and governance across an organization. It is particularly useful for data engineers and analysts who need to define business metrics, create derived tables, and manage data access controls in a collaborative environment. Use cases include building centralized data warehouses, creating self-service analytics dashboards, and enforcing data quality standards.
