Deploying and Managing Datastore
Chapter 11 described how to initialize a Datastore document database. Now, you will see how to create entities and add properties to a document database. You’ll also review backup and restore operations.
Adding Data to a Datastore Database
You add data to a Datastore database using the Entities option in the Datastore section of the console. The Entities data structure is analogous to a schema in relational databases.
You create an entity by clicking Create Entity and filling in the form that appears. Here you will need to fill in Kind, which is analogous to a table in a relational database, and Properties, as shown in Figure 12.10.
