-title: Graphs and Natural Data Modeling
+title: Graph Data Models 101
 description:
   Graphs provide an alternative to tabular data structures, allowing for a more
   natural way to store and retrieve data
 ---
 
+When building an app, you might wonder which database is the best choice. A
+traditional relational database that you can query using SQL is a familiar
+choice, but does a relational database really provide a natural fit to your data
+model, and the performance that you need if your app goes viral and needs to
+scale up rapidly?
+
+This tutorial takes a deeper look at data modeling using relational databases
+compared to graph databases like Dgraph, to give you a better understanding of
+the advantages of using a graph database to power your app. If you aren't
+familiar with graph data models or graph databases, this tutorial was written
+for you.
+
+## Learning Goals
+
+In this tutorial, you will learn about graphs, and how a graph database is
+different from a database built on a relational data model. You will not find
+any code or syntax in this tutorial, but rather a comparison of graphs and
+relational data models. By the end of this tutorial, you will be able to answer
+the following questions:
+
+- What is a graph?
+- How are graphs different from relational models?
+- How is data modeled in a graph?
+- How is data queried from a graph?
+
+Along the way, you might find that a graph is the right fit for the data model
+used by your app. Any data model that tracks lots of different relationships (or
+_edges_) between various data types is a good candidate for a graph model.
+
+Whether this is the first time you are learning about graphs or looking to
+deepen your understanding of graphs with some concrete examples, this tutorial
+will help you along your journey.
+
+If you are already familiar with graphs, you can jump right into our coding
+example for [React](/courses/messageboardapp/react/overview/introduction/).
+
+If you are a SQL user and you'd like to learn how common SQL syntax maps to
+similar GraphQL syntax so you can use your SQL knowledge to jump-start your
+GraphQL learning journey, see
+[Introduction to Dgraph for SQL Users](/courses/datamodel/sql-to-dgraph/overview/introduction).
+
+## Graphs and Natural Data Modeling
+
 Graphs provide an alternative to tabular data structures, allowing for a more
 natural way to store and retrieve data.
