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 lakes

With big data streaming from various origins, in varying formats and models, and at various speeds, it is no surprise that we need to be able to ingest this data into a fast and scalable storage system that is flexible enough to serve many (current and future) analytical processes. When it comes to such a dynamic storage system, traditional storage systems don't fit big data challenges for streaming and batch processing applications. That is where the concept of data lakes comes in.

We can store all structured and unstructured data at various scales, in a centralized repository. Such a repository is referred to as a data lake. We can store our data as it is, without having to structure or preprocess the data. In addition to that, we can execute various types of analytics and visualizations, and even real-time analytics.
