Understanding LookML Concepts to Ace the LookML Developer Certification Exam
LookML is an open source language used to define the structure and view of data within a database. It is designed to make it easier to build, maintain, and share database connections and data models. LookML is a powerful tool for data analysts and developers, and the LookML Developer Certification Exam is an important part of demonstrating a mastery of the language. This article will provide an overview of some of the key concepts and terminology in LookML to help prepare for the exam. The first concept to understand is the LookML Model. A LookML Model is a set of files that define the structure of a database. This includes tables, fields, and field types, as well as relationships between the tables. It is the core of the LookML language, and is used to define the data structure and view of the database. The next concept to understand is the LookML View.
A LookML View defines how the data in a LookML Model is presented. This includes selecting which fields to display, setting filters, and creating calculated fields. Understanding how to create and modify LookML Views is essential for passing the LookML Developer Certification Exam. The third concept to understand is the LookML Dashboard. A LookML Dashboard is a graphical representation of the data in a LookML Model. It is an interactive way to explore and analyze the data, and includes visualizations such as charts and graphs. Understanding how to create and modify LookML Dashboards is also essential for passing the LookML Developer Certification Exam.
Finally, the LookML Developer Certification Exam will also require an understanding of LookML Parameters. Parameters are variables that can be passed to a LookML View or Dashboard to modify the output. This includes variables such as dates and filters, as well as more complex parameters such as calculations and custom queries. By understanding these core concepts and terminology of LookML, you will be better prepared to pass the LookML Developer Certification Exam. With the right approach and dedication, you will be able to demonstrate your knowledge of the language and your ability to use it effectively.
Learn the Best Practices for Writing LookML Code and Passing the LookML Developer Certification Exam
1. Structure your LookML code to have a consistent indentation style and format. This makes your code easier to read and understand.
2. Use meaningful names for views, fields, and joins to make code easier to read. Avoid using jargon and abbreviations that may not be understood by others.
3. Use the “view” statement to create a single view per file. This avoids repetition and makes code easier to read.
4. Use the “include” statement to include other LookML files. This allows for easier code maintenance and better organization.
5. Use the “extend” statement to extend other views. This allows you to extend existing functionality without repeating code.
6. Use the “model” and “explore” statements to define relationships between views and fields. This helps to keep your code organized and ensures that fields are correctly mapped to their corresponding views.
7. Use the “sql_on” and “sql_off” statements to define custom SQL code that will be used for query optimization. This helps to ensure that your queries run efficiently.
8. Use the “dimension_group” and “measure” statements to define the fields that will be used in the query. This allows for easy access to the fields you need for your query.
9. Use the “parameter” statement to define parameters that can be used in your LookML code. This allows for easy customization of your LookML code to accommodate different user preferences.
10. Use the “derived_field” statement to create fields based on calculations or other logic. This allows for efficient reuse of code.
11. Follow LookML best practices to ensure that your code is properly documented and easy to maintain. Proper documentation of your code will make it easier for others to understand and use. By following these best practices, you can ensure that your LookML code is organized, efficient, and easy to understand.
