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.

Data model structures

Data models deal with data variety characteristics of the big data. Data models describe the characteristics of the data. There are two main sources of data:

  • Structured data
  • Unstructured data

Structured data

Structured data relates to data that has a defined length and format. Some common examples of structured data include numbers, dates, and groups of words and numbers, which are called strings. In general, structured data follows a pattern like that in Figure 3.1. Generally, the data has predefined columns and rows. Some of the data columns could be missing, but they are still classified as structured data:

As shown in Figure 3.2, most of the structured...
