Indexing in Magento is the process of data conversion. All changes concerning products, categories, prices, catalog search index must be updated. Indexing is carried out with the purpose of improvement of webstore productivity.
Magento stores significant amount of information in many database tables. To optimize site performance, Magento accumulates information with indexes. If you change any product prices Magento should reindex all prices so that the changes are displayed on the website.
