NoSQL And Data ModelingBig Challenges in Data Modeling

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.
