CHAPTER 4Implement data access

A program can use variables to store values as it is running, but it needs a means of persisting data. We have already touched on data storage at several points in this book, in Skill 3.1 in the section “Choose the appropriate data collection type,” we considered how best to map information in our application onto the data types that C# offers. Later in the section “Using JSON,” we saw how data in objects can be serialized. And finally, in the “Use the Entity Framework to design your data storage” section we created classes that were automatically mapped into database tables for use in an application. Before you read this chapter, it is worth going over those topics so that they are fresh in your mind.
