Release 10.1A: OpenEdge Development:
Java Open Clients

> ## Using Java SDO classes to access Property meta data

> The OpenEdge `ProDataGraph` relies on the Java SDO `Type` and `Property` interfaces to encapsulate the base `DataObject` interface meta data for the columns of a `ProDataObject`. This meta data specifies both the list of `Property` objects (properties) that define a `DataObject` and specifies the Java data types that define the individual column properties and whether the properties are single- or many-valued. For a `ProDataObject`, the `ProDataObjectMetaData` then maps the schema information for temp-table fields to the corresponding `Property` objects.

> This section describes the `Type` and `Property` interfaces in terms of base `DataObject` meta data support with reference to the OpenEdge `ProDataGraph`, as appropriate.
