To model data is to know data. In this course, you will learn how to create a relational data model, incorporate entities from a decomposed JSON document, create a dimensional model, and build a database from a script generated from your data model.
How can you get value from your data if you don’t know your data? How many data projects have you started only to go through the same process of hunting down someone who knows something about the data you need to work with? Do they still work with the company? This is why we model data. In this introductory course, Enterprise Data Modeling: Getting Started, you will learn about the relational data model and normalization techniques. First, you will explore the NoSQL data stores and the JSON data format. Next, you will learn about OLAP and the dimensional model. Finally, you will take what you have learned and put into practice with a few demonstrations including creating a physical data model from a logical model to generate a script to build a database. By the end of the course, you will have a firm understanding of what a data model is, different types of data models, how to apply normalization, the JSON data format, and how to create both a relational and dimensional data model.

Course Overview Hi everyone, my name is Joe Cline, and welcome to my course, Enterprise Data Modeling: Getting Started. Have you ever been asked to create a data model, but were confused by terminology or how to apply the relational data model's normal forms? Have you ever had to work with NoSQL data stores, but didn't know how to model that data for import into your relational environment? Over the last decade more and more NoSQL database systems have been developed, by the relational database system is still the most common. We also still use the dimensional model for data warehouses, But did you know that you can use it for Hadoop data lakes too? Because some of the major topics that we'll cover in this course include terminology and concepts of data modeling, the relational data model including an explanation of normalization and normal forms, NoSQL data structures, including the JSON data format, dimensional modeling for reporting and analytics, and there'll be plenty of demos to show you how to put what you've learned into practice with a professional, enterprise-grade data modeling tool. By the end of this course you will have a firm understanding of what a data model is, the difference between different types of data models, how to apply normalization techniques to third normal form, how to break down a JSON data format, create a dimensional data model, promote your relational logical data model to a physical data model, and generate a script so you can run and build an actual database ready for application development. This is an introductory data modeling course so no previous data modeling experience is necessary, but after completing this course you should feel comfortable creating and maintaining models for the enterprise data tier. I hope you'll join me on this journey to learn about modeling enterprise data with the Enterprise Data Modeling: Getting Started course, only on Pluralsight.
