Hands-On Big Data Modeling

By: James Lee, Tao Wei, Suresh Kumar Mukhiya

Overview of this book

Modeling and managing data is a central focus of all big data projects. In fact, a database is considered to be effective only if you have a logical and sophisticated data model. This book will help you develop practical skills in modeling your own big data projects and improve the performance of analytical queries for your specific business requirements. To start with, you’ll get a quick introduction to big data and understand the different data modeling and data management platforms for big data. Then you’ll work with structured and semi-structured data with the help of real-life examples. Once you’ve got to grips with the basics, you’ll use the SQL Developer Data Modeler to create your own data models containing different file types such as CSV, XML, and JSON. You’ll also learn to create graph data models and explore data modeling with streaming data using real-world datasets. By the end of this book, you’ll be able to design and develop efficient data models for varying data sizes easily and efficiently.

Streaming Sensor Data

Streaming data is becoming omnipresent. Sensor data is present everywhere, including in heartbeats, brainwaves, electrodermal activity from the skin, audio signals from humans, temperature data, and so on. Since data is continuously streaming, this sensor data requires a complex approach. In this lesson, you will gain experience in using diverse forms of streaming sensor data, along with the analysis of sensor data.

In this chapter, we will cover the following topics:

  • Exploring streaming sensor data
  • Data lakes, and how to use them in batch processing
  • The difference between schema-on-write and schema-on-read
  • Temperature sensor data, and visualizing it with Python
