1. Introduction of looker :

Data is one of the most valuable assets for any business, but making sense of it can be challenging without the right tools. Looker is a modern business intelligence platform designed to help companies turn complex data into clear insights. By connecting directly to data sources, Looker enables teams to explore, visualize, and share information effortlessly. Whether it’s tracking sales performance, understanding customer behaviour, or improving operational efficiency, Looker makes it easy for everyone in an organization to access meaningful insights without requiring technical expertise.

What sets Looker apart is its ability to transform raw data into actionable knowledge. With customizable dashboards, real-time reporting, and seamless collaboration features, Looker ensures everyone—from executives to frontline staff—has the right information at the right time. It’s more than just presenting data; it’s about empowering businesses to make confident, informed decisions that drive growth, efficiency, and innovation.

How Looker Works

Looker’s architecture and workflow are designed to simplify data exploration while maintaining flexibility and scalability. At its core, Looker relies on a robust modelling layer to bridge the gap between raw data and insightful visualizations. Here’s a clear breakdown of its key components:

LookML One of the foundational elements of Looker is LookML, its proprietary modelling language used to define how data is structured, connected, and displayed. It acts as a bridge between raw database data and the visual reports seen in Looker. With LookML, data teams can:

• Set consistent rules for data calculations, filtering, and presentation.
• Simplify complex database queries, enabling business users to explore data without writing code.
• Ensure reliable and repeatable insights across all dashboards and reports. In essence, LookML transforms raw data into clear, reliable insights accessible across an organization. This foundational layer sets the stage for Looker’s core components, enabling seamless interaction with data at every stage of analysis.
• Models: These define how data from various sources is organized and connected. Models act as the foundation for all data exploration and analysis.
• Views: A view specifies a list of fields (dimensions or measures) and maps them to an underlying table or derived table. Views can also join other views, creating relationships defined in the model file.
• Explores: Explores are interactive environments where users can query, filter, and analyse modelled data without requiring SQL or programming knowledge.
• Dashboards: Insights derived from Explores are visualized and organized in dashboards. These dashboards present critical metrics in an easy-to-digest format and can be tailored to meet team-specific needs.
  Together, these components enable Looker to transform raw data into actionable insights. Its intuitive interface and robust modelling capabilities empower organizations to make informed, data-driven decisions confidently in today’s competitive landscape.
