Résumé :
This SAP Note discusses the importance of creating database indexes to improve system performance. The note outlines the reasons for requiring indexes due to costly database statements and the steps for creating these indexes in SAP systems. Index creation should start in the development environment followed by a test in the quality assurance environment, before moving it to production. Special attention is given to table operations during index creation, suggesting performance implications related to table size. For larger tables, index creation should occur during periods of low activity or downtime. Factors like parallel processing, use of specific database tools, and updating of cost optimizer statistics post-index creation are also highlighted to ensure efficient implementation.
