# Modelling If you have ever battled with Excel crashing, nested SQL scripts, or attempted to find the template you used for the Quarterly Performance Report, modeling is for you. Fundamentally, data modeling is about building insights with data - and automating it. Modeling means you’ll be removing the row you don’t need, combining multiple data sources and calculating metrics like Customer Acquisition Cost or Daily Profit Margin. We have built a visual code editor where you can use [Action](/less-tech/modelling/action-guides.md)s as lego building blocks to transform your data into insights. What’s really smart is that Less stores the output of your analysis in whatever database you are connected to. That means that if you schedule your model to run daily, you’ll have updated answers ready daily. Lastly, a visual builder - like the one in Less - helps colleagues trust your results. Your colleagues can check every step from raw data to analysis table and - hopefully - get a better sense of what happens. #### --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://resources.less.tech/less-tech/getting-started/modelling.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
