Introduction

SPD Server 4.5 uses improved architectures that enable features like the ability to support data tables that contain over 2G observations. The new architectures provide functionality that is needed in today's data marts, but the current generation of SPD Server tables use metadata architectures that are not backwards compatible with SPD Server 3.x software.

SPD Server 4.x tables use architectures that use SAS 9 metadata. SPD Server 3.x tables use architectures that use SAS 8 metadata. The two metadata architectures are not compatible. However, SPD Server 4.5 provides a conversion utility SPDSCONV that permits SPD Server 3.x customers to convert existing tables for use with SPD Server 4.x. The SPDSCONV utility is designed to be run by the SPD Server Administrator.
