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.

Defining Data Models

This chapter walks the reader through various structures of data. The main types of structures are structured, semi-structured, and unstructured data. We will also be applying modeling techniques to these types of datasets. In addition, readers will learn about various operations on the data model and various data model constraints. Moreover, the chapter gives a brief introduction to a unified approach to data modeling and data management. We will discuss the following topics:

  • Identifying different data model structures, including structured and unstructured data
  • Recognizing different data model operations, including selection, projection, union, and join
  • Understanding different data model constraints and explaining why constraints are used to specify the semantics of the data
  • A unified approach to data modeling and data management
