Abstract

An attribute is received for storage. Whether the attribute is searchable or non-searchable in storage is determined. Storing the attribute as a searchable attribute comprises storing the attribute in a database table corresponding to a hierarchical class-based object. Storing the attribute as a non-searchable attribute comprises storing the attribute together with one or more other non-searchable attributes as a set of attributes. The set of attributes is stored in a database location outside the database table corresponding to the hierarchical class-based object, and the database location is accessed before the database table. A unique attribute identifier is associated with the attribute to distinguish between a name of the attribute and a name of one of the one or more other non-searchable attributes in the event that the name of the attribute and the name of the one of the one or more other non-searchable attributes are assigned the same name.
