As with any database, the data model that you design is important in determining the logic your queries and the structure of data in storage. This practice extends to graph databases, with one exception. Neo4j is schema-free, which means that your data model can adapt and change easily with your business. Need to start collecting a new field and capture new analysis?
Or need to change the way you interpret a customer or other entity and modify its definition? You may have worked for a company where each area or department defines a domain differently. Take, for instance, a generic customer domain. To different areas within the business, a customer can be defined as different types of individuals. These definitions may also change over time or the company may decide to unify the meaning of a customer across departments.
If you have worked with other types of databases, you will already be familiar with the development and administrative work that any of these scenarios entail. However, Neo4j allows you to effortlessly adjust detailed and broad changes across pieces or the entirety of the graph. Whether it is small changes over time or a broad definition that includes a variety of needed information about your entities, the database is able to handle it.
It is simply up to the developers and architects to determine the structure of the data model and how to define entities for queries. In the next few paragraphs, we will introduce a few different ways to look at different data sets and show how each impacts queries and performance for traversing graph data.

Ten years ago, if you asked me to model an online dating site with people, answers to questions, freeform essays, etc, I would have built an attractive, normalized structure like this:. In fact, back in I built and launched an early version of Similarity that had a structure almost exactly like this.
It worked just fine In retrospect, if I ever had real traffic, this schema would not have performed. It requires queries just to fetch a single profile. Rendering 50 match results might have required hundreds of queries. Enough caching, database replication, and clever query optimization might have made this work at scale The load requirements of a modern mass-consumer web application are so severe that traditional database modeling falls apart; there’s so much denormalization and hackery required that your system stops looking like an RDBMS.
