LookML: The Modeling Language of Looker
LookML (Looker Modeling Language) is Looker’s proprietary language for data modeling. It allows users to define the data structure and relationships in a way that is reusable and scalable. LookML abstracts SQL queries, making it easier for data analysts to manage complex datasets without deep SQL knowledge.
Defining Dimensions and Measures
In LookML, dimensions are attributes of your data (e.g., date, product name), while measures are aggregations (e.g., sum of sales, average price). Defining these elements correctly is crucial for accurate data analysis.
Creating Relationships
LookML allows you to define relationships between different data tables, enabling complex joins and data transformations. This helps in creating a comprehensive data model that supports various analytical needs.
Using LookML Parameters
LookML includes parameters such as filters, sets, and parameters, which provide additional flexibility in querying and transforming data. These parameters enable users to create dynamic and interactive data models.
