Preface

Chapter 8. The Data Layer

The data layer of the Siebel Repository defines the physical schema of tables, columns, and indexes for storing customer, administrative, and repository data. Developers must understand how the objects of this layer and their relationships establish the physical foundation for the business layer. Configuration activities on this layer are limited to additive changes. This means that developers are only allowed to create new tables or columns but not to modify data layer objects defined by Oracle engineering.

This chapter is structured as follows:

  • Understanding tables, columns, and indexes

  • Considerations for custom schema changes

  • Using preconfigured extension tables

  • Creating custom columns

  • Creating custom indexes

  • Creating custom tables

  • Applying schema changes to local and server databases
