Making Sense of NoSQL clearly
and concisely explains the
concepts, features, benefits,
potential, and limitations of
NoSQL technologies. Using
examples and use cases,
illustrations, and plain, jargon-
free writing, this guide shows
how you can effectively
assemble a NoSQL solution to
replace or augment the
traditional RDBMS you have
now.

10 Tips For Modeling in a Hybrid World
1. Models require a modeler
2. Data modeling tools are essential – choose wisely
3. There are many types of data models: know which ones you need
4. Modeling does not have to happen at the same time in every project. It should happen at the right time
5. Modeling is not just schema design. Think outside the boxes and lines

10 Tips for Modeling in a Hybrid World
6. A data model is much more than a diagram
7. You will need training. More than you think.
8. Team members may not understand modeling. They will need training
9. NoSQL is not one thing. Learn many patterns
10.Modern data architectures are likely hybrid solutions. You can’t just support one part.

This book is written for anyone
who is working with, or will be
working with MongoDB, including
business analysts, data
modelers, database
administrators, developers,
project managers, and data
scientists.
