Chapter 4. The SimpleDB Data Model

The entire data model for SimpleDB is comprised of four concepts—domains, items, attributes, and values. We will explore these concepts in detail in this chapter. The conceptual hierarchy of a domain in SimpleDB is like the following chart and shows the relation between the different components.

In this chapter, we will cover:

Interacting with a domain
Metadata for a domain
Interacting with items in a domain
Interacting with the attributes of an item
Storing multiple values for an attribute
SimpleDB constraints on domain, items, attributes, and attribute values
