Sample Schemas

Most of the included accounts are administrative accounts, but Sample Schema accounts are also present. The Oracle Database Sample Schemas are a set of interlinked schemas that enable Oracle documentation, and Oracle by Example Series, to illustrate common database tasks:

The human resources (hr) schema is useful for introducing basic topics. An extension to this schema supports Oracle Internet Directory demos.
The order entry (oe) schema is useful for dealing with matters of intermediate complexity. Many datatypes are available in this schema, including nonscalar datatypes.
The online catalog (oc) subschema is a collection of object-relational database objects built inside the oe schema.
The product media (pm) schema is dedicated to multimedia datatypes.
The information exchange (ix) schemas demonstrate Oracle Advanced Queuing capabilities.
The sales history (sh) schema is designed for demos with large amounts of data. An extension to this schema provides support for advanced analytic processing.
