Introduction Data modeling is one of the most important steps in designing and building a database. Before storing information in any system, businesses need a clear structure for how that data will be organized, connected, and maintained. This is where data modeling becomes essential. Think of data modeling as creating a blueprint for a database. … Read more
Data Pipeline Data pipeline: Mapping data flow from collection to analysis for organizational insights. Source, process, deliver for analytics efficiency. Database vs Schema vs Table Database: Organized collection of related data, like a file cabinet for storing information. Schema: Blueprint defining structure and organization within a database. Table: Grid-like structure within a schema, where data … Read more
In this notebook, we are going to parse raw data from a single topic in our multiplexer bronze table. As you can see, in our architecture diagram, we will create the orders silver table. Let us start by copying our dataset files. Before starting, we need to cast our Kafka binary fields as strings. Here … Read more
Learning Objectives You will understand the available ingestion models in the bronze layers and the difference between them, and you will learn how the ingested data will be promoted to the silver layer. When setting up ingestion into the bronze layer, we need to decide how input datasets should be mapped to the bronze tables. … Read more
Introduction In modern data engineering, ensuring data quality is just as important as building scalable pipelines. No matter how advanced your architecture is, poor data quality can lead to incorrect analytics, broken dashboards, and unreliable machine learning models. This is where Delta Lake check constraints come into play. Check constraints allow you to enforce rules … Read more
What is Data? Data is nothing but raw and unprocessed facts and statistics stored or free flowing over a network. Data becomes information when it is processed, turning it into something meaningful. Collecting and storing data for analysis is a human activity and we have been doing it for thousands of years. In order to … Read more
