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.

Sensor data

Sensor data is everywhere, and it can be used in various fields, including the health industry, weather prediction, sound analysis, and video streaming. Let's explore some of the uses of sensor data, as follows:

  • Heath sensor data: A lot of medical institutions record patient vital signs in real time. These vital signs include heart rate, electrodermal activities, brainwaves, temperature, and more. This real-time sensor data, when collected, is massive, and can be considered big data. This data can be used by ICT technology to diagnose patients.
  • Weather data: The real-time streaming of weather data is done by many satellites, in order to collect the vital signs for the weather. This data is used in weather prediction.
  • Sensor data from IoT: A lot of sensor data can be collected from custom Internet of Things (IoT) devices, such as the Raspberry Pi, Apple watches...
