About Deciding What Data to Import

The Siebel CRM Data Model provides for many possible business needs and configurations. Many of the tables, columns, and indexes provided with Siebel CRM might not be relevant to your business. Because DB2 stores information in all columns, including NULL columns, consider carefully what data you want to import into your Siebel database. Importing unnecessary data increases the size of tables and indexes, which can affect performance. For information on removing columns and indexes and reducing column sizes using Siebel Tools, see Customizing a Development Environment.
