Chapter 11: Dealing with Data
You should know that no matter what your application does, you will end up dealing with persistence sooner or later. Whether it's a payment, a post on social media, or anything else, information has no value if it's not stored, retrieved, aggregated, modified, and so on.
For this reason, data is very much a point of concern when designing an application. The wrong modeling (as we saw in Chapter 4, Best Practices for Design and Development, when talking about Domain-Driven Development) can lead to a weak application, which will be hard to develop and maintain.
In this chapter, we are taking data modeling a step further and discussing the ways your objects and values can be stored (also known as data at rest, as opposed to data in motion, where objects are still being actively manipulated by your application code).
In this chapter, we will cover the following topics:
- Exploring relational databases
- Introducing key/value stores...
