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.

DBMS and MapReduce-style systems

In the preceding sections, we discussed distributed and parallel DBMS. But it is important to know that all the data problems discussed previously may not be required for big data processing. It depends on the type of applications you are trying to build. In this section, we are going to discuss the need for MapReduce-style systems.

DBMS has effectively used parallelism with efficient storage and better query performances. They have an efficient algorithm to optimize performance and increase efficiency. However, these classical DBMSes do not take machine failure into account, unlike MapReduce, which was originally developed for the distributive processing of large amounts of data. MapReduce was done over Hadoop filesystems, and hence the issues such as node failure were automatically accounted for. It was utilized in complex applications, such...
