# Example tables and data for use in DynamoDB
The *Amazon DynamoDB Developer Guide* uses sample tables to illustrate various aspects of DynamoDB.
****
| Table name | Primary key |
| --- | --- |
| ProductCatalog | Simple primary key: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AppendixSampleTables.html) |
| Forum | Simple primary key: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AppendixSampleTables.html) |
| Thread | Composite primary key: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AppendixSampleTables.html) |
| Reply | Composite primary key: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AppendixSampleTables.html) |
The *Reply* table has a global secondary index named *PostedBy-Message-Index*. This index will facilitate queries on two non-key attributes of the *Reply* table.
****
| Index name | Primary key |
| --- | --- |
| PostedBy-Message-Index | Composite primary key: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/AppendixSampleTables.html) |
For more information about these tables, see [Step 1: Create a table in DynamoDB](getting-started-step-1.md) and [Step 2: Write data to a DynamoDB table](getting-started-step-2.md).

The following sections show the sample data files that are used for loading the *ProductCatalog*, *Forum*, *Thread* and *Reply* tables.
Each data file contains multiple `PutRequest` elements, each of which contain a single item. These `PutRequest` elements are used as input to the `BatchWriteItem` operation, using the AWS Command Line Interface (AWS CLI).
