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.

Structures of Data Models

In this chapter, we will continue to shed light on big data modeling with specific approaches, including vector-space models (VSMs) and graph-data models. The reader will learn about the concept of different structures of data models using hands-on exercises such as exploring graph-data models with Gephi and a semi-structured data model of JSON files. In this chapter, we will be covering the following topics:

Learning about various structures of the data model
Learning about the vector-data model using Lucene
Exploring the graph-data model using Gephi
Exploring the semi-structured data model of JSON files and XML files
