A Practical Guide to ICF Catalogs

Book Description

This IBM® Redbooks® publication gives a broad understanding of integrated catalog facility (ICF) catalog environments. It includes suggestions for design, planning, and deployment activities to help you create and maintain a balanced and efficient catalog environment.

Four scenarios are provided to illustrate sample implementations of typical activities associated with an organization's requirements.
