Summary of Database Concepts

At this point, we're ready to dive into the building of our Recruiting app. But first let's recap what we've learned about databases. Whether this was your first introduction to databases or whether you're already an experienced database developer who's new to the Lightning platform, the important things to remember are:

• A database is an organized collection of information.
• A database table stores information about a single type of person, thing, or concept—such as a job position. In the Lightning platform, we use the term object here (even though an object is much more than this, as you'll see).
• A database row, or record in Lightning platform terms, represents a single instance of an object—such as the SW Engineer position.
• A field stores a particular piece of information on a record.
• Relationships define the connection between two objects, and objects are related to each other through the use of common fields.
