DBT or Data Build Tool is an open-source tool that helps data analysts and engineers to transform and analyze data in a structured and efficient way. It is a popular tool used by companies like Airbnb, Lyft, and Slack. This cheat sheet will provide you with an overview of the concepts, topics, and categories related to DBT.
Models: Models are the core building blocks of DBT. They define how data is transformed and loaded into a database. Each model represents a table in the database.
Sources: Sources are the raw data that is loaded into the database. They can be files, databases, or APIs.
Seeds: Seeds are a type of source that contains static data. They are useful for testing and development.
Snapshots: Snapshots are a type of model that captures the state of a table at a specific point in time. They are useful for auditing and compliance.
Tests: Tests are a way to validate the data in a model. They can be used to check for missing values, data types, and other issues.
Macros: Macros are reusable code snippets that can be used across models. They are useful for reducing code duplication and improving maintainability.
Packages: Packages are collections of models, macros, and tests that can be shared across projects. They are useful for promoting best practices and standardization.
Data Modeling: Data modeling is the process of designing the structure of a database. It involves defining tables, columns, and relationships between tables.
Data Transformation: Data transformation is the process of converting raw data into a format that is suitable for analysis. It involves cleaning, filtering, and aggregating data.
Data Loading: Data loading is the process of inserting data into a database. It involves creating tables, inserting data, and updating data.
Data Validation: Data validation is the process of ensuring that data is accurate and complete. It involves checking for missing values, data types, and other issues.
Data Quality: Data quality is the measure of how well data meets the requirements of its intended use. It involves ensuring that data is accurate, complete, and consistent.
Data Governance: Data governance is the process of managing the availability, usability, integrity, and security of data. It involves defining policies, procedures, and standards for data management.
Data Integration: Data integration is the process of combining data from multiple sources into a single view. It involves transforming, cleaning, and loading data from different sources.
SQL: SQL is the language used to interact with databases. It is used to create tables, insert data, and query data.
Python: Python is a popular programming language used for data analysis and machine learning. It is used in DBT for writing macros and tests.
Git: Git is a version control system used for managing code changes. It is used in DBT for managing packages and collaborating on projects.
Cloud Services: Cloud services like AWS, Google Cloud, and Azure are used for hosting databases and running DBT.
Analytics Tools: Analytics tools like Looker, Tableau, and Power BI are used for visualizing and analyzing data. They can be integrated with DBT for real-time data analysis.
ETL Tools: ETL tools like Talend, Informatica, and DataStage are used for extracting, transforming, and loading data. They can be integrated with DBT for data integration.
Data Warehousing: Data warehousing is the process of storing and managing large amounts of data. It involves creating a central repository for data that can be accessed by multiple users.
DBT is a powerful tool for data transformation and analysis. It provides a structured and efficient way to manage data and ensures that data is accurate, complete, and consistent. This cheat sheet provides an overview of the concepts, topics, and categories related to DBT. Use it as a reference guide to get started with DBT and improve your data management skills.
